Living organisms also interact with one another. This include getting food,
breathing, and reproducing. So, both kinds of interactions between living

organisms and between living and non-living components – are important
for survival in any habitat.

What is an Ecosystems?
An ecosystem includes all the living organisms and non-living elements of a
habitat and how they interact. Organisms rely on non-living components

for food, shelter, and protection. In every ecosystem, communities of living
organisms interact closely with non-living factors.

There are two major types of ecosystems:
• Aquatic ecosystems: These include ponds, rivers, and lakes.
• Terrestrial ecosystems: These include forests, farms, grasslands and

even a single large tree like a banyan or mango tree.
• Ecosystems can be small or large, and sometimes, they overlap.

• Every ecosystem stays balanced only when living and non-living
components support one another.
