NEET BIOLOGY

Detailed explanation-1: -Limiting factors are resources or other factors in the environment that can lower the population growth rate. Limiting factors include a low food supply and lack of space. Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off.

Detailed explanation-2: -Limiting factors are sometimes helpful because they can keep the population from getting too large.

Detailed explanation-3: -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-4: -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. These limiting factors determine an ecosystem’s carrying capacity, or maximum population size the environment can support given all available resources.

Detailed explanation-5: -Density-dependent limiting factors cause a population’s per capita growth rate to change-typically, to drop-with increasing population density. One example is competition for limited food among members of a population.
