bacteria and fungi

5

Consume their food

heterotrophs

Each step in a food chain or a food web is known as a

Trophic leve

6

Series of feeding relationships is known as a 

food chain

7

Alternate name for a heterotroph

consumer

8

Ecosystems with similar climates and dominant communities are know as 

biomes

8

What is passed between organims in a food chain or food web?

energy (only 10%)

nutrients/organic matter
