Food Chain
a sequence where energy is transferred from one organism to the next as each organism eats another organism
Food Web
a diagram that shows many feeding relationships in an ecosystem
Trophic level
Each step in the transfer of energy through a food chain or food web

Plant uses energy from sunlight to make sugar and then is then passes on to consumers
Describe one way consumers
depends on producers: cows need to eat grass to get energy
List two types of consumers
