Which part of an ecosystem make up living things.
Biotic
What is true about the organisms found at the top of the food chain?
There are fewer populations of these organisms.
What would most likely result if all plants in an area were destroyed?
consumer populations would increase, decomposer populations would increase, consumer populations would decrease. decomposer populations would decrease.
consumer populations would decrease because plants provide them with energy.
