NEET BIOLOGY

Detailed explanation-1: -According to the logistic growth model, a population first grows exponentially because there are few individuals and plentiful resources. As the population gets larger and approaches the environment’s carrying capacity, resources become more scarce and the growth rate slows.

Detailed explanation-2: -If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive. If the population exceeds the carrying capacity for a long period of time, resources may be completely depleted. Populations may die off if all of the resources are exhausted.

Detailed explanation-3: -As resources are depleted, population growth rate slows and eventually stops: This is known as logistic growth. The population size at which growth stops is generally called the carrying capacity (K), which is the number of individuals of a particular population that the environment can support.

Detailed explanation-4: -Overshoot. A population is in overshoot when it exceeds available carrying capacity. A population in overshoot may permanently impair the long-term productive potential of its habitat, reducing future carrying capacity.

Detailed explanation-5: -The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds. Explore carrying capacity with these curated classroom resources.
