Answer:
The environmental resistance factors are all the factors or things that keep a population of the organisms from endlessly increasing i.e. keep a check on it. . They reduce the chances for reproduction, affect the health of organisms/individuals, and raise the death rate in the population.
The environmental resistance factors include the factors that are biotic and abiotic.
• The biotic factors are things like a predation, a parasitism, lack of food, competition with other organisms and disease.
• Abiotic factors include factors like drought, fire, temperature, and even the wrong amount of sunlight could affect it.
