Question

16: Ecosystem is formed only with biotic components true or false​

Answer:

False

Explanation:

Ecosystems contain biotic parts as well as abiotic factors.

Answer 2

Answer

Environmental resistance factors are all the things that keep a population of organisms from endlessly increasing. They lower the chances for reproduction, affect the health of organisms, and raise the death rate in the population. Environmental resistance factors include factors that are biotic (living) and abiotic (non-living). Biotic factors are things like predation, parasitism, lack of food, competition with other organisms and disease. Abiotic factors include drought, fire, temperature, and even the wrong amount of sunshine. 

So the given statement is true.
