Question

The force in an ecosystem which opposes the unchecked growth of population is :

• A. Mortality
• B. Fecundility
• C. Biotic control
• D. Environmental resistance

Answer 1

The correct option is D Environmental resistance

The environmental factors which can check the growth of population size constitute the environmental resistance. These include predators, food, water, nesting sites, similar competitors, etc. All living things tend to reproduce until the point at which their environment becomes a limiting factor. No population, human or otherwise, can grow indefinitely; eventually, some biotic or a biotic variable will begin to limit population growth.

So, the correct option is 'Environmental resistance'.
