Science:  Habitat and communities

We are lucky in Delta to have access to many different types of habitats.  We are learning about our habitat through a variety of activities.  We are using a simplified Science Unit available from Davies and Johnson Associates to begin reading concept area text.   It may be helpful to preview or review the lessons below at home.

Lesson 1 — Introduction to Habitats

There are three words which fit together.  They are environment, habitat, and niche.  The environment is everything around where something grows — air, plants, soil, water.  A habitat is a special area in the environment where a living thing such as an animal, plant, fish, bird or insect can grow and survive.  Examples of habitat are oceans and the rain forest.  A niche is the part of a habitat where a certain living thing can grow and survive.  

Lesson 2 — Habitat

Why are animals, plants and insects not the same all over the world?  The answer is that depending on their different habitat they need different characteristics to survive.  Living things called organisms interact with other organisms in their habitat.  They depend on each other for food, shelter, safety and new growth or reproduction.

Lesson 3 — Help and Competition in a Habitat

All organisms interact with things in their habitat.  Organisms either help each other or compete with each other.  An organism such as a plant may help animals by providing food, shelter or protection.  Animals assist plants by carrying their seeds to a new location either on their body or in their droppings.  Organisms compete with each other when they need the same things for survival.  This could be space to live and grow, food, water, reproduction or safety.   If an organism cannot meet its needs due to competition it may die or move to a better habitat.  When an organisms has found a place that has everything it needs to stay alive and grow, it has found its niche.

Lesson 4 — Dangers to Habitat

Smithsonian’s National Zoological Park

In this lesson we learn that humans and other animals and organisms all depend on their habitats.  They all need food, water, shelter and space to survive.  If any parts of a habitat are lost, the animals may be harmed.
There are a number of dangers to habitat including chemical use, hunting, drought and extreme weather, pollution, mining and forestry and climate change.  We will determine which of these are natural dangers and which are caused by humans (Habitat Dangers).  To finish the lesson we will go on an Adventure to save Panda habitat in China.

Lesson 5 — habitat research project

To finish this unit each student will choose a habitat they are interested in, research it and complete this research organizer.  You will then present your findings to the class using a method of your choice — poster, powerpoint presentation, video, model, diorama or ?  You will use this marking guide to determine your grade.  As each student presents their findings you will gather information on this worksheet.

There are a few very important ecosystems that provide optimal habitat and will be vitally important to sustaining wild turkey numbers in the future.

Here are the types of habitats on which we should focus our efforts to ensure these critical components are provided for decades to come.

Habitats around rivers and streams (riparian zones)

What is it? Vegetation near river or stream banks

What’s the problem? Water availability is the greatest limiting factor in many areas

Why does it matter? Streamside habitats provide critical travel corridors and ribbons of high-quality mast-producing trees and shrubs

What the NWTF is doing: Protects and restores vital riparian habitats through conservation easements, removal of invasive species, establishing native plant species, and timber stand improvement.

Oaks and grasslands

What is it? Open canopies create lush ground cover with plenty of grasses, broadleaf plants and shrub

What’s the problem? A lack of active forest management and habitat conversion to agriculture and development have diminished them to less than 1 percent of their original amount

Why does it matter? Lightly forested grasslands, with oaks to provide roosting areas and food for wild turkeys

What the NWTF is doing: Works on public and private lands to remove some of the trees using selective herbicides and prescribed fire to restore oak savannas

Pine savannas

What is it? Open forested canopies dominated by pine trees, lush ground cover and interspersed grassland openings
What’s the problem? A lack of fire and conversion to other land uses has led to a dramatic loss of these habitats, experts estimate less than 1 percent still exists today

Why does it matter? Critical to wild turkeys and other upland wildlife, providing food, cover, brood habitat and nesting areas

What the NWTF is doing: Works on public and private lands to restore pine savannas through timber thinning, prescribed fire and reestablishing native grasses and forbs

Wildlife openings (often called, forest clearings, meadows, pastures)

What is it? Young stages of grass, forb, tree and shrub growth

What’s the problem? A lack of mowing, prescribed fire, disking or selective herbicide treatments, amounting to less than 2 percent of its habitat is open on in early growth stages

Why does it matter? Small 1-to-5-acre openings are best for wild turkeys, since they tend to use the forested edges of the openings

What the NWTF is doing: Creates and maintains thousands of acres of wildlife openings with the help of our partners each year

4 habitats of living organisms and their characteristics (general table)

The first habitat of organisms was water. It was in her that life was born. With historical development, many organisms began to populate the Earth’s ground-air environment. As a result, terrestrial plants and animals appeared, which evolved, adapting and getting used to the new conditions of existence. During the life of organisms on earth, the surface layers of the lithosphere gradually turned into soil, according to Vernadsky V.I., “the bio-inert body of the planet” — a substance that arose during the joint activity of living organisms and their habitat. Bio-inert bodies are natural mineral compounds processed through the vital activity of plant and animal organisms.

Aquatic and terrestrial organisms began to populate the soil, creating a special complex of its inhabitants. Probably, the formation of parasites and symbionts proceeded in parallel, the environment of which in water, on land and in soil became other organisms — hosts and cohabitants. At the moment, 4 habitats of organisms are distinguished: aquatic, terrestrial-air, soil and living organisms.

4 habitats of living organisms table

4 habitats


Adaptations of organisms to the environment

Example organisms


High density, thermal conductivity, transparency, strong pressure drops, poor aeration, illumination decreases with depth, relatively uniform (homogeneous) in space and stable in time

Streamlined, oblong body shape, buoyancy, presence of mucous membranes, development of air cavities, osmoregulation

Small plants and animals, jellyfish, algae, active swimmers — fish, dolphins, seals.


Abundance of light and oxygen, low air density, sharp fluctuations in temperature, high atmospheric mobility, moisture deficiency, heterogeneous. The most complex both in terms of properties and diversity in space

Development of the supporting skeleton, mechanisms of thermoregulation, economical use of water, high efficiency of redox processes, developed organs for the assimilation of atmospheric oxygen

Terrestrial plants, animals, protozoa, bacteria, fungi

Soil habitat

Lack or complete absence of light, high density, lack or excess of moisture, lack of oxygen, relatively high content of carbon dioxide, loose substrate structure filled with a mixture of gases and water. Created by living organisms

Rolled body shape, small size, strong body integument, skin respiration, reduction of the organs of vision, some have a digging apparatus, developed muscles

Bacteria, fungi, worms, beetles, ants, protozoa, insect larvae, other arthropods, some large animals (mole, shrew)


Presence of easily digestible food, constancy of temperature, osmotic, salt conditions, no threat of desiccation, protection from enemies, lack of oxygen, limited living space

Simplification of all organ systems, reduction of some of them, appearance of attachment organs, high fecundity, complex developmental cycles with a change of one or more hosts

Parasites — lice, fleas, helminths, fungus, protozoa and bacteria, symbionts — bacteria

Paragraph 4. Habitats of organisms

Question 1. What is the biosphere?

The biosphere (from the Greek words «bios» — life and «sphere» — a ball) is a special shell of the Earth, within which life spreads.

Question 2. What habitats of organisms do you know?

Habitats: ground-air, water, soil, and some living organisms can be a habitat for others.

Question 1. What habitats of living organisms do you know?

Habitats: Ground-air environment, water, soil, as well as living organisms themselves can be a habitat for other organisms.

Question 2. What properties are characteristic of the aquatic habitat?

Water has a buoyant force, its density is greater than that of air. Water is able to accumulate and retain heat. Salt composition of water is of great importance for aquatic organisms.

Question 3. Why is it considered that the ground-air environment is more complex and diverse than the water?

The properties and composition of air masses are of the greatest importance for organisms living in the ground-air environment. The density of air is much lower than the density of water. Air temperature can change very quickly and over large spaces. The chemical composition of the air is important for terrestrial organisms. And also in the ground-air environment, living organisms live in conditions of different humidity.

Question 4. What is soil?

Soil is the upper loose fertile layer of land.

Question 5. What is the role of soil in plant life?

The soil has a special property — fertility, the ability to provide plants with nutrients and moisture, to create conditions for their vital activity. The more minerals and humus in the soil, the more fertile it is. The yield of cultivated crops and wild plants depends on soil fertility.

Question 6. What are the main features of organisms that use the bodies of other organisms as a habitat?

The conditions of life inside another organism are characterized by greater constancy compared to life in other environments. Therefore, organisms that find a place for themselves in the body of plants or animals often completely lose the organs and even organ systems necessary for free-living species.

Question 7. What organisms do you know that live inside other organisms? Have you felt the influence of such inhabitants on yourself?

Bacteria, viruses, flatworms (liver fluke, tapeworm, bovine tapeworm, tapeworm), subcutaneous mites, etc. All such organisms that live and multiply inside other organisms, in particular in the human body, cause a variety of diseases. Symptoms include disruption of the gastrointestinal tract, pain in the abdomen, nausea and bouts of vomiting, in some cases itching is observed in the anus. Weakness, fatigue, irritability. Uncontrolled changes in weight. Similar symptoms can be supplemented by sleep disturbances.


Why are organisms that live in the terrestrial-air environment more diverse than the inhabitants of the aquatic?

The ground-air environment was mastered by spiders, insects, reptiles, birds, animals, and plants. A wide variety of conditions (temperature indicators, pressure, high oxygen concentration, altitudinal zonality, climate, etc.) of the ground-air environment led to the presence of a wide variety of living organisms from the earth’s surface to the ozone layer and from the north pole to the south. The living conditions of animals in the aquatic environment are very different from the land-air environment: the density of water is almost 1000 times greater than the density of air, there are stronger pressure drops in water, less oxygen, more active absorption of sunlight than in air.
