š¬ Think about it
Look around your classroom. Some things are alive, like you and your friends. Some are not, like the walls and the fan. Nature works the same way. Living and non-living things share every place. Let us see how they fit together.
What are biotic and abiotic components?
- Living beings in a habitat are the biotic components.
- Non-living things are the abiotic components.
- Both are found in every habitat.
Biotic (living)
Abiotic (non-living)
Plants, animals, microbes
Air, water, soil, sunlight, temperature
Fish, frogs, grass, trees
Water, mud, rocks, heat
They grow, eat and reproduce
They do not grow or reproduce
How does a fish survive in a pond?
- A pond gives food, oxygen, shelter and space.
- Fish get food (biotic need) from small plants and animals.
- Fish get oxygen (abiotic need) from the water.
- So a pond offers all the conditions a fish needs.
Example:
A pond is like a home that gives a fish its meals, its air, and its safe space — all in one place.
Why do different organisms live in different places?
- Every organism needs special conditions to survive.
- So some live on land and some live in water.
- Different habitats offer different living conditions.
- A snake active at night and a rodent active by day share one habitat.
Important Points
- Each habitat has its own biotic parts and physical conditions.
- Physical conditions include air, sunlight, water, temperature and soil.
- Different organisms use the same resources in different ways.

Give two abiotic components of a pond.
View Answer
Water and sunlight (also air, mud or temperature). -
From where does a fish get oxygen?
View Answer
From the water, which is an abiotic need. -
Why can a snake and a rodent live in one habitat?
View Answer
One is active at night and the other by day, so they face different conditions. -
Is sunlight biotic or abiotic?
View Answer
Abiotic, because it is non-living.
Important Definitions
- Biotic components — the living beings of a habitat, like plants and animals.
- Abiotic components — the non-living things of a habitat, like air, water and soil.
