EVERYDAY SCIENCE

Detailed explanation-1: -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-2: -In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.

Detailed explanation-3: -Logistic growth and carrying capacity In reality, there is simply not enough space or resources for natural populations to continue to grow unchecked. Limiting factors within every ecosystem, such as the availability of food or the effects of predation and disease, prevent a population from becoming too large.

Detailed explanation-4: -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-5: -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.
