1 of 8
Give the equation for photosynthesis and an example of a producer that carries out this process?
6CO2 + 6H2O + light energy --> C6H12O6 + 6O2 Green Plants
2 of 8
What is a consumer?
An organism that obtains energy by 'eating' another.
3 of 8
Organisms feeding on producers / plants are known as ___ ___, and the organisms feeding on these are known as ___ ____?

What are detritivores?
Animals such as earthworms that carry out the same work as decomposers.
