This change best illustrates the 3rd answer choice, Loss of Habitat.
The plants aren't migrating, but are rather only surviving in areas where there is enough moisture to support life. The wildflowers are not adapting to grow in dryer conditions, and the species is not going extinct, as there are still some areas where the plants can get enough moisture.
Hope this helped!
Answer:
<u><em>Active Transport</em></u>
Explanation:
<u><em>active transport
</em></u>
During <u><em>active transport</em></u>, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Because gravity pulls towards the center of the earth evenly in all directions, giving earth a spherical shape.
Commensalism is a situation in nature where there is an association between two organisms that benefits one but does not help nor harm the other.
Let's go through each example in order to find one with commensalism.
A). Honey bees that feed on the pollen of cornflowers and help the flowers reproduce.
This is not a form of commensalism as both organisms mutually benefit from the association.
B). Barnacles ride on a gray whale's back to obtain food, and the whale is not harmed.
This is a form of commensalism. The barnacles benefit from riding on the whale's back as they obtain food. The whale is also unharmed in the process.
C). Squirrels and chipmunks eat the same nuts in a forest where food is scarce.
This is not a form of commensalism as neither organism benefits. There is an increased competition for food that harms both of the organisms.
D). Prairie dogs often collect and eat food in groups so they are better protected from enemies.
This is not a form of commensalism as the interaction of the organisms is within the same species. In order for commensalism to take place, two different species must interact.
The best example of commensalism is B.
