C. Secondary consumers

Explanation:

Organisms in food web are group into producer, primary consumer, secondary consumer, terrier consumer and or decomposer.

The kelp are the producers, usually in green plants form and they starts the trophic level first this is followed by the sea orchins which are herbivores and they feed on the kelp in abundance of quantity.

The otters are carnivores animals that feeds on the herbivores(primary consumer) they are called the secondary consumer and they feed on primary consumer to get their energy. Tertiary consumers are usually the last on the food trophic level for this family and the feed on the secondary consumer (otter).

C. Secondary consumers

Explanation:

This is because, in the kelp community, sea otters are secondary consumers because the feed on sea urchins. The kelp is a producer because they are plants and the photosynthesized to produce food. Sea urchins are herbivores that feed on kelp plants, therefore they are primary consumer and sea otters are secondary consumers because they feed on sea urchins.

its like this, "if i give a plant an unlimited amount of sunlight,then the plant will grow to its largest possible size."

what do the different brain waves do?
