Answer:
Mutualism
Commensalism
Parasitism
Explanation:
In mutualism, both organisms benefit.
<em>Ex</em>. Sea anemone and clownfish. Clownfish gives the anemone food, the anemone allows the clownfish to use it as a home.
In commensalism, one organism benefits, while the other is neither harmed nor benefited.
<em>Ex</em>. Sharks or whales and remora fish. The remora rides along the belly of whales or sharks and when it eats, the pieces that float around, the remora eats the excess.
In parasitism, one organism is benefited, while the other is hurt.
<em>Ex. </em>Dogs and fleas. The fleas are constantly biting and feeding off of the dog's skin. The dog gets bitten and itches a lot.
Mutualism and commensalism are similar because at least one organism is benefited.
Parasitism and commensalism are different because instead of one organism not getting hurt, like in commensalism, that happens in parasitism.

How is meiosis related to natural selection
Meiosis creates genetic variability in a population, this means that more and more organisms have different traits. Some of these traits make an organism better adapted to survive in its environment. Those with these traits are more likely to survive (natural selection).
