AP BIOLOGY

Detailed explanation-1: -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-2: -Thus, organisms tend to compete for their limited availability in the ecosystem. Different limiting factors affect the ecosystem. They are (1) keystone species, (2) predators, (3) energy, (4) available space, and (5) food supply.

Detailed explanation-3: -In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations.

Detailed explanation-4: -Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor.

Detailed explanation-5: -Limiting factors are things that can limit the size of a population such as food, water, shelter, disease, nesting sites, predation, and parasitism.
