FOOD CHAIN

Page 2: Kilapio, john darius

FOOD CHAIN

Linkages of organisms within an ecosystem, in which each link feeds on the one before it and is fed on by the one after it.

Page 3: Kilapio, john darius

Food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals.
