Answer:

pressure gradient

Explanation:

The correct answer would be pressure gradient.

<em>A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.</em>

In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.

Which of the following would have the greatest ecosystem diversity? Group of answer choices a lake a prairie the land an organic
miv72 [106K]

Options:

  • a lake
  • a prairie
  • the land an organic farmer uses to raise crops to feed his dairy cattle
  • a large island in the tropics that has snowcapped mountains

Answer:

a large island in the tropics that has snowcapped mountains

Explanation:

The land a farmer uses is likely to be quite highly regulated in order to ensure that his dairy cattle thrive. That means the growth of certain plants will be controlled, and this will likely impact diversity.

A lake and a prairie could have diverse and balanced ecosystems. However, due to the limited habitat are likely only to harbour specific organisms. E.g. the lake will only harbor organisms that thrive in water environments.

A large island will, first of all, have a lot of space to support diversity. It is in the tropics, meaning it will have species suited to a hot and wet environment. Since it is an island, there will also be the involvement of sea/ocean dwelling creatures. However, there is also mountainous habitat that has snow, meaning it is high up and cold. This provides a habitat for even more species adapted to different environments.

Therefore, the island will be the most diverse.
