Question

Deserts, tropical forests, prairie grasslands, and coniferous forests have distinct climates and certain species, and are all examples of ____. Question 3 options: 1) different species 2) ecosystems with the highest biodiversity 3) ecosystems with low genetic biodiversity 4) biomes 5) populations

Question 4 (1 point)

The role a species plays in its ecosystem is its ____.

Question 4 options:

trait

Question 5 (1 point)

Species with broad niches are described as ____ species.

Question 5 options:

generalist

Question 6 (1 point)

In 1957, Brazil imported wild African honeybees to help increase honey production, but the bees displaced some native honeybee populations, which led to a reduced honey supply. These African honeybees could be described as ____.

Question 6 options:

endemic

Question 7 (1 point)

Species that provide early warnings of environmental change in a community or an ecosystem are called ____.

Question 7 options:

native species

Question 8 (1 point)

In a population of wild bees, a mutation resulted in slightly larger wingspan in some of the bees. This larger wingspan made the bees more efficient in their flights to flowers to collect nectar. Thus, these bees became more successful. This trait was passed on to offspring, and eventually the larger wingspan variety of bee replaced their smaller-winged relatives completely.

Because this mutation produced a specific wing trait that was passed onto offspring, the mutation must have occurred ____.

Question 8 options:

because of the type of pollen the bee collected

Question 9 (1 point)

It could be said that ____ favored the bee with the larger wingspan, and so the ____ evolved.

Question 9 options:

mutation; population

Question 10 (1 point)

____ are species whose roles have a large effect on the types and abundance of other species in an ecosystem.

Question 10 options:

Keystone specie

Question 11 (1 point)

Which characteristic must be true in order for a trait to be impacted by the forces of natural selection and then play a role in the process of biological evolution?

Question 11 options:

The trait must be a behavioral characteristic of the organism.

Question 12 (1 point)

The American alligator is a(n) ____ because it plays a number of important roles in the ecosystems where it is found in the southeastern United States.

Question 12 options:

keystone species

Question 13 (1 point)

We can say that on a long-term basis, the ____ principle of sustainability has especially helped life on the earth to adapt to drastic changes in environmental conditions.
