IMMUNOLOGY

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: -Biotic or biological limiting factors are things like food, availability of mates, disease, and predators.

Detailed explanation-3: -Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.

Detailed explanation-4: -These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.

Detailed explanation-5: -Abiotic factors, such as light intensity and water availability, affect population size because when these conditions are ideal then organisms can grow and reproduce successfully.
