Which of the following is expected to happen to a species' population when resources are stable over a long period of time and the species have reached carrying capacity?(1 point)

Question

Responses

The population will stay the same.
The population will stay the same.

The population will decrease.
The population will decrease.

The population will die out.
The population will die out.

The population will increase.

Answer 1

When resources are stable over a long period of time and a species has reached its carrying capacity, the expected outcome is that:

The population will stay the same.

This means that the number of individuals in the population will stabilize around the carrying capacity, with births and deaths balancing each other out.

Answer 2

Which factor may increase a rabbit population?(1 point)
Responses

decrease in predators
decrease in predators

decrease in space
decrease in space

decrease in food
decrease in food

decrease in temperature

Answer 3

The factor that may increase a rabbit population is a:

decrease in predators.

When there are fewer predators, rabbit survival increases, leading to a potential increase in their population.

Answer 4

A group of mountain gorillas has 10 members. How big is the group after 4 females emigrate, 2 females immigrate, 2 gorillas are born, and a male dies?(1 point)

13

Answer 5

To calculate the size of the group after the changes you've mentioned, we can break it down:

1. Starting size: 10 members
2. 4 females emigrate: 10 - 4 = 6 members
3. 2 females immigrate: 6 + 2 = 8 members
4. 2 gorillas are born: 8 + 2 = 10 members
5. 1 male dies: 10 - 1 = 9 members

Therefore, the size of the group after all these changes is:

9.

Answer 6

Predator/prey interactions regulate the populations of both groups. Which chain of events follows from an increase in predators?(1 point)
Responses

increase in prey → decrease in predators → decrease in prey
increase in prey → decrease in predators → decrease in prey

decrease in prey → increase in predators → decrease in prey
decrease in prey → increase in predators → decrease in prey

increase in prey → increase in predators → decrease in prey
increase in prey → increase in predators → decrease in prey

decrease in prey → decrease in predators → increase in prey

Answer 7

The chain of events that follows from an increase in predators is:

decrease in prey → increase in predators → decrease in prey.

This means that as predators increase, they will eat more prey, causing the prey population to decrease. As the prey population decreases, the predators may also face a decrease in their population due to a lack of food.

Answer 8

The population change equation is Population change = (Natality – Mortality) + (Immigration – Emigration). Which equation would create a stable population?(1 point)
Responses

natality - mortality = immigration - emigration
natality - mortality = immigration - emigration

natality + immigration = mortality - emigration
natality + immigration = mortality - emigration

natality + immigration = mortality + emigration
natality + immigration = mortality + emigration

natality + mortality = immigration + emigration

Answer 9

To create a stable population, the population change equation (Population change = (Natality – Mortality) + (Immigration – Emigration)) must equal zero. This can be expressed as:

Natality - Mortality + Immigration - Emigration = 0.

Rearranging this equation leads to:

Natality - Mortality = Emigration - Immigration.

However, writing it in a different way that also reflects a stable population can be:

natality + immigration = mortality + emigration.

So the correct answer is:

natality + immigration = mortality + emigration.
