What is a modern human intervention in the phosphorus cycle?

Mining phosphate for use as a fertilizer

Planting crops that release a lot of phosphate

Capturing atmospheric phosphate for use as a fertilizer

Replacing phosphate with magnesium

What is an ecosystem?

Production of a large number of small offspring, each of which receives little parental investment.

How many trophic levels does an omnivore feed on within an ecosystem?

Omnivores feed at all trophic levels.

2

3

None, because the various trophic levels do not apply

A chaparral plant that is usually only seen in the first couple of years after a fire is also called what?

A fire-follower

A fire germinator

Ash vegetation

A smoke germinator

Which of the following is true about amensalism?

Amensalism can happen when a bigger, more established organism out competes a smaller organism for resources.

Which of the following is a density-independent factor that does not become more limiting as the population increases?

Flash flood from a thunderstorm

Available habitat

Water

Reproductive rate

What is a niche?

A role thats played by a particular species in an ecosystem

The type of prey that a predator hunts.

The area where a predator hunts.

A area thats suitable for a particular organism to live in

What type of mimicry occurs when a harmless animal mimics a dangerous or unpalatable animal?

Batesian mimicry

Chemical mimicry

Mullerian mimicry

Coloration mimicry

What is coevolution?

Coevolution occurs when the fitness of two different species is tightly linked and these two species evolve in response to evolutionary changes in each other.

What is niche differentiation?

When more than one species with almost the same fundamental niche adapt to become specialists in different aspects of the fundamental niche.

Environmental factors

What is a population?

The individual organisms belonging to the same species.

All of the ecosystems on the planet combined.
