Ecology Review - Day 1

In which eukaryotic organelles does photosynthesis occur?

Only 10% of the energy is passed on from one trophic level to the next. 90% is lost as heat due to cellular respiration or waste.

The fourth trophic level where animals eat secondary consumers or below.

Herbivores--The second trophic level where herbivores eat the primary producers.

Autotrophs--The bottom trophic level where all organisms produce their own food, usually by photosynthesis.

Heterotrophs that get energy and nutrition from dead or decaying organisms or their waste products and recycle nutrients back to the ecosystem.
