Now look at figure given alongside where one simple feeding
rela onship is shown:
Grass → Hare → Leopard
This is a food chain– a direct link showing
"who eats whom."
Another example of a food chain using the
same ecosystem could be:

Grass → Grasshopper → Chameleon → Snake
→ Eagle

A food chain is a simple, straight-line
sequence that shows the transfer of food
energy from one organism to another in an
ecosystem. Another food chain in grassland

A food chain is a straight sequence showing who eats whom. A food web is a
more realistic picture, showing how different food chains are

interconnected in an ecosystem. In a food web, one organism can be part of
multiple food chains, which helps maintain the balance in nature

All living organisms grow, reproduce, perform various life activities, and
eventually die. During their life processes, they also produce waste, such
as:

• Dead bodies
• Leftover food

• Other organic waste
This waste becomes part of the ecosystem and is broken down by

decomposers, playing a vital role in recycling nutrients.
