Question 1

When two or more species compete with one another their niches are said to ____________________.

Accepted Answer

The answer of When two or more species compete with...

Question 2

Organisms with clumped distributions are fairly rare.

Accepted Answer

Organisms with clumped distributions are actually quite common, as many species live in social groups or rely on certain resources that are localized in specific areas.

Question 3

A population exceeding its carrying capacity will suffer a(n)____________________ or ____________________, unless the excess individuals can switch to new resources or move to a new area.

Accepted Answer

The answer of A population exceeding its carrying capacity will...

Question 4

The most common form of population dispersion found in nature is ____________________.

Accepted Answer

The answer of The most common form of population dispersion...

Question 5

____________________ occurs when a member of one species feeds directly on all or part of a member of another species.

Accepted Answer

The answer of ____________________ occurs when a member of one...

Question 6

In _______________, two species behave in ways that benefit both by providing each with needed resources.

Accepted Answer

The answer of In _______________, two species behave in ways...

Accepted Answer

The answer of One of the factors determining the rate...

Question 8

The answer of ____________________ is a competitive interaction between species...

Question 11

The southern sea otter has been classified as a(n)____________________ species because in their absence, kelp forests would probably be destroyed.

Accepted Answer

The answer of The southern sea otter has been classified...

Question 12

____________________ is the combination of all factors that act to limit the growth of a population.

Accepted Answer

The answer of ____________________ is the combination of all factors...

Question 13

Humans are exempt from population overshoot and dieback.

Accepted Answer

Humans are not exempt from population overshoot and dieback. It is a possibility if the human population exceeds the carrying capacity of the Earth's resources. So, it is crucial for humans to work towards sustainable living and population control to avoid such a scenario.

Question 14

Bad-tasting, bad-smelling, toxic, or stinging-prey species advertise their characteristics using ____________________.

Accepted Answer

The answer of Bad-tasting, bad-smelling, toxic, or stinging-prey species advertise...

Question 15

The carrying capacity of any given area is not fixed.

Accepted Answer

The carrying capacity can change depending on various factors such as resource availability, environmental changes, and population dynamics. Therefore, it is not fixed or constant.

Question 16

Large mammals, such as elephants and rhinoceroses, are especially vulnerable to extinction because of their reproductive patterns.

Accepted Answer

Large mammals have low reproductive rates and long gestation periods, making them more vulnerable to population declines caused by hunting, habitat loss, and other threats. It takes a long time for them to reach sexual maturity and produce offspring, and the survival rate of their young is often low. This makes it difficult for their populations to recover from declines, and they are therefore at increased risk of extinction.

Question 17

When two different species interact over a long time, changes in the gene pool help both species to become more competitive or avoid competition. This is called _______________,

Accepted Answer

The answer of When two different species interact over a...

Question 18

Some prey species make themselves larger or mimic a predator, both of which are called ____________________.

Accepted Answer

The answer of Some prey species make themselves larger or...

Question 19

The growth rate of a population increases as its size nears the carrying capacity of its environment.

Accepted Answer

The growth rate of a population typically decreases as its size nears the carrying capacity of its environment, due to increased competition for resources.

Question 20

The gradual change in species composition in a given area is called ____________________.

Accepted Answer

The answer of The gradual change in species composition in...
