Question

A population _____ follows a period of ______.
A.) decline, overshoot
B.) increase overshoot
C.) increase scarcity
D.) scarcity, dieback
​

Answer 1

Answer:

The correct option is A. decline, overshoot

Explanation:

Carrying capacity can be described as the maximum number of a particular population size that an ecosystem can hold. The resources such as food, water, space etc are enough for a specific number of species. Sometimes, when a population diebacks, there are more number of resources present than the consumers, so the consumers start to reproduce and expand. The population of these organisms then might overshoot the carrying capacity.

Answer 2

A population increase follows a period of overshoot.

Explanation:

Population is the number of living people that live together in the same place. Whereas overshoot or Human overpopulation (or population overshoot) is occurs when the ecological footprint of a human population exceeds the carrying capacity. The overshoot occurs when the population temporarily exceeds the long-term carrying capacity of its environment. Rapid population growth leads to the environmental change. The consequence of overshoot is called a collapse, a crash or a die-off where there is a decline in population density. This population crash is a sudden decline in the numbers of members in a population, species or group of organisms

The increase in a population occurs when the birth rate is higher than the death rate, also when immigration exceeds emigration and when a combination of these factors is present. Other three main processes of change of population are birth rates, death rates and migration.

A population grows very quickly and exceeds its environment's carrying capacity is said to overshoot its environment's capacity. A catastrophic dieback when the population plummets to well below its maximum usually follows an overshoot. In many cases the populations undergo repeated the overshoot-dieback cycles.
