Explanation:

Symbiosis has three main types. Mutualism is when both organisms benefit. Commensalism is when one benefits and the other is unaffected. Parasitism is when one benefits and the other is harmed.

1. Mutualism: In mutualism, both organisms benefit. The example of an ostrich and gazelle shows that they both gain (watching for predators while feeding).
2. Commensalism: In commensalism, one organism (barnacle) benefits (hitching a ride) and the other (whale) is neither helped nor harmed.
3. Parasitism: In parasitism, one organism (flea) benefits (getting blood meal) and the other (dog) is harmed.

Answer:

1. Mutualism; both; benefit
2. Commensalism; helped; harmed
3. Parasitism; benefits; harmed
