Carbohydrates

Organisms that get their energy by eating other organisms
Herbivores

Decomposers
consumers that get their food from breaking down dead organisms
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
How is energy transferred?
Plant use energy from sunlight to make sugar and then is then passed on to consumers
Describe one way consumers
depends on producers; cows need to eat grass to get energy
List two types of consumers
