Organisms and Environment

Learning Objectives

By the end of this lesson, students will be able to:

Simple and Detailed Lesson Notes

1. What is Environment?

The environment is everything that surrounds us.
It includes living things and non-living things.

Living Things (Biotic Components)

These are things that have life.
Examples: plants, animals, humans, birds, insects, microorganisms.

Non-living Things (Abiotic Components)

These are things that do not have life.
Examples: sunlight, air, water, soil, rocks, temperature.

Both living and non-living things together make our environment.

2. Components of the Environment

(a) Sunlight

Sunlight provides light and heat.

Plants need sunlight to make food through photosynthesis.

Animals and humans get energy by eating plants or plant-eating animals.

Sunlight also helps maintain temperature on Earth.

(b) Air

Air contains oxygen, carbon dioxide, nitrogen, and other gases.

Humans and animals breathe oxygen to live.

Plants use carbon dioxide to make food and release oxygen.

(c) Water

All living things need water to survive.

Plants need water to grow.

Animals drink water for survival.

Water helps in digestion, cleaning, and regulating temperature in our bodies.

(d) Soil

Soil provides a place for plants to grow.

Soil contains minerals, nutrients, air, water, and tiny organisms.

Soil supports animals like earthworms and insects.

(e) Other Organisms

Living things depend on each other.

Example:

Cow eats grass.

Tiger eats other animals.

Humans eat both plants and animals.

Plants depend on animals for carbon dioxide.

3. Interrelationship Between Components of the Environment

All components of the environment are connected and depend on each other.

Examples:

Sunlight helps plants make food.

Plants release oxygen needed by animals.

Animals release carbon dioxide needed by plants.

Soil provides minerals to plants.

Water helps plants and animals survive.

This connection forms a balanced environment.

—

4. How Organisms Get What They Need to Survive (Objective 2)

Every organism gets its basic needs from its environment:

Plants get:

Sunlight for making food

Air (carbon dioxide)

Water from soil

Nutrients from soil

Animals get:

Food (plants or other animals)

Water from rivers, ponds, lakes

Oxygen from air

Shelter from trees, caves, or houses

Humans get:

Food from plants and animals

Water from nature

Air for breathing

Resources like wood, fuel, medicines, metals

Thus, organisms cannot live without their environment.

—

5. Population Growth and Its Impact on the Environment (Objective 3)

Population means the number of people living in a place.

When population increases very fast, it causes problems:

(a) More Use of Natural Resources

More people = more food, water, and land needed

Forests are cut down for farming and houses

(b) Pollution Increases

More waste is produced

More vehicles release smoke

Water sources get polluted

(c) Loss of Wildlife

Animals lose their homes because forests are destroyed

Some animals may become endangered

(d) Less Clean Air and Water

Factories and vehicles make air dirty

Rivers and lakes get polluted

(e) Soil Problems

Too much farming can reduce soil nutrients

Soil can become dry and less fertile

Conclusion:

Population growth should be controlled and resources should be used wisely to protect the environment.

—

Summary

The environment has living and non-living components.

Sunlight, air, water, soil, and other organisms are all connected.

Every living organism gets its basic needs from the environment.

Population growth can harm the environment by causing pollution, deforestation, and resource shortage.
