Biology

AnnZ [28]4 years ago

A LOSS OF DISSOLVED OXYGEN IN THE WATER is the primary and direct cause of death of aquatic animals during eutrophication or what is also known as hypertrophication. This is the enrichment of a water body with excessive chemical nutrients which can be a problem in marine habitats, as it can cause algal blooms. With this is the occurrence of dense growth of plant life and death of animal life from lack of oxygen.

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.
