The Energy Connection
Organisms can be divided into 3 groups based on how they obtain energy;
this process is called Photosynthesis
Producers include plants, algae, and some bacteria
2) CONSUMERS – are organisms that eat producers and other organisms to obtain their energy.
There are several kinds:
a) Herbivores – consumers that only eat plants
b) Carnivores – consumers that only eat animals
c) Omnivores – consumers that eat both plants and animals
d) Scavengers – consumers who eat dead animals
3) Decomposers – are organisms that get their energy by breaking down the remains of dead organisms
