Question

What are abiotic factors? how can they affect the population dynamics? give some examples?

Answer 1

Abiotic factors are things that aren't living that effect an environment, like pH (how acidic the soil is), the temperature, amount of light, and so on. These can effect a population by making it more difficult to survive, perhaps creating more competition over available resources and so on. So for example, if the soil is really acidic in an area, a population of plants may not be able to grow well in that environment.
