How Nature Works in 
Harmony
Elephant Corridor
In several parts of India, elephants often enter farms and villages 
when vegetation is scarce and waterholes dry up in their natural 
habitat.
Shrinking Habitats
Changes in rainfall and temperature affect vegetation. 
Cutting down trees for roads and buildings makes it 
worse.
Wildlife Movement
When forests cannot support wildlife, animals tend to 
move into human habitats.
Wildlife Corridors
Ecologists have identified corridors to allow safe 
movement of animals between large forest areas.

How Do We Experience and 
Interpret Our Surroundings?
What is a Habitat?
A habitat is simply a place where an organism 
lives. It could even be just the bark of a tree.
Different habitats have different kinds of 
plants and animals that interact with each 
other and adapt to survive in the surrounding 
conditions.

Components of a Habitat
Biotic Components
Living beings in a habitat:
Plants (trees, grass, algae)
Animals (fish, birds, insects)
Microorganisms
Abiotic Components
Non-living things in a habitat:
Water
Soil
Air
Sunlight
Temperature

Who All Live Together in Nature?
P o p u l a t i o n
A group of organisms of the same type living in 
a specific habitat at a given time. For instance, 
all the fish of a single species in a pond form a 
population.
C o m m u n i t y
A collection of different populations sharing 
the same habitat. This includes all the plants, 
animals, and microorganisms interacting within 
that habitat.
