LIFE SCIENCE

Detailed explanation-1: -A limiting factor is anything that constrains a population’s size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.

Detailed explanation-2: -Carrying capacity can be defined as a species’ average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.

Detailed explanation-3: -Some factors affecting human population growth (and other organisms’ population growth) include predation, disease, scarcity of vital resources, natural disasters and an inimical environment.

Detailed explanation-4: -They are (1) keystone species, (2) predators, (3) energy, (4) available space, and (5) food supply.
