What is a food Chain?

FOOD CHAIN The food chain shows us what eats what in a

community.

They show the movement of FOOD ENERGY from one organism to the next.

FOOD CHAIN

From the food-web above, name:a) Two primary consumersb) One secondary consumerc) Explain why all food chains begin with green plantsd) If the Owls and Snakes were killed what would happen to numbers

of: Mousee) If the snakes were killed what would happen to the population of

kite?

What is a food Chain?

Every living thing needs energy in order to live. Animals get energy from the food they eat, and all

living things get energy from food. Plants use sunlight, water and nutrients to get energy (in a

process called photosynthesis).

FOOD CHAIN

A food chain is the sequence of who eats whom in a biological community (an

ecosystem) to obtain nutrition.
