4.4 Trophic Levels

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

Trophic level=feeding level
producers eg. carrot (photosynthesis)=> carrotfly (primary consumer)=>flycatcher (secondary consumer)=> sparrow (tertiary consumer)
at some point, these living organisms die.
Decomposers such as fungi and bacteria recycle molecules of the living organism into nutrients.
