NEET BIOLOGY

Detailed explanation-1: -The common limiting factors in an ecosystem are food, water, habitat, and mate. The availability of these factors will affect the carrying capacity of an environment. As the population increases, food demand increases as well. Since food is a limited resource, organisms will begin competing for it.

Detailed explanation-2: -Immigration is the permanent inward movement of some individuals coming from outside into an existing population. This increases population density and would not limits growth.

Detailed explanation-3: -Resources. Resources such as food, water, light, space, shelter and access to mates are all limiting factors. If an organism, group or population does not have enough resources to sustain it, individuals will die through starvation, desiccation and stress, or they will fail to produce offspring.

Detailed explanation-4: -Limiting factors to population growth can be biotic or abiotic. Biotic factors are living factors such as plants and animals as food sources. Abiotic factors are physical factors such as temperature and water resources. Food, water, and living space are three of the most important limiting factors to populations.
