food web
each step in the transfer of energy through a food chain or food web
trophic level
plant uses energy from the sunlight to make sugar and then is passed on to consumers
how is energy transfered
describe one way consumers
depends on producer: cows need to eat grass to get energy
list two types of cunsumers
