4.4

4.4 Recall the names given to different trophic levels to include producers, primary, secondary and tertiary consumers and decomposers

Trophic: feed

Photosynthesis (Producer: turns light energy into chemical energy) à Herbivore (Primary consumer: chemical energy of plant into chemical energy of the fly) à Carnivore (Secondary consumer: chemical energy from one form to another)à Top Carnivore (Tertiary consumer: chemical energy from one form to another)

At some stage, they die. They are broken down by decomposers (fungi & bacteria). They break down complex molecules into nitrates and phosphates.
