Slade · Answer 1

Ans. Option (B).

Biotic factors are defined as all the living things found in an ecosystem. All animals, microbes, insects, and plants are grouped as biotic factors. On the other hand, non-living things or environmental factors, sun, water, rocks, and air are abiotic factors.

Fishes, sea anemones, and crustaceans are animals, so they are abiotic factors. Thus, the correct answer is option B). fish, sea anemones, and crustaceans.

Luis · Answer 2

Answer: B) fish, sea anemones, crustaceans.

Explanation: Biotic factors are the living components of an ecosystem. They include all types of plants and animals.

Fish, sea anemones, and crustaceans are all living, or biotic, factors that can be found in marine ecosystems. Sunlight, salt water, and rocks are all abiotic, or nonliving, factors.
