|
|
|
It continues to grow higher and higher.
|
|
|
The population starts to die off and returns to the carrying capacity.
|
|
|
The population will go extinct due to lack of resources.
|
|
|
None of the above
|
Detailed explanation-1: -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: -Carrying capacity can be defined as a species’ average population size in a particular habitat. 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.
Detailed explanation-4: -For populations which grow exponentially, growth starts out slowly, enters a rapid growth phase and then levels off when the carrying capacity for that species has been reached. The size of the population then fluctuates slightly above or below the carrying capacity.
Detailed explanation-5: -Housing and feeding so many people has accelerated the destruction of natural habitats, while higher levels of consumption, particularly in some richer parts of the world, have also increased the exploitation of natural resources and led to growing levels of pollution.
