An orange roughy fish eats squid and small fish. it also is eaten by predators like dolphins and sharks. where would the orange roughy most likely appear on a food web?
1. it is a primary producer because it provides food for the dolphins and sharks.
2. it is a tertiary consumer because most of the things it eats are secondary consumers.
3. it is a secondary consumer because it eats two types of things.
4. it is a primary consumer because it has both predators and prey.
just found ou the answer is the 2nd one.

The correct answer is 2. It is a tertiary consumer because most of the things it eats are secondary consumers.

Explanation:

In food chains, there are different levels this includes primary producers such as plants that produce own energy; primary consumers that are those feeding on primary producers and are herbivores; secondary consumers that feed on primary consumers and are carnivores; and tertiary consumers that feed on primary and secondary consumers.

In the case presented, the orange fish can be classified as a tertiary consumer because it eats squids that commonly feed on small fishes or shrimps and therefore squids are a secondary consumer; also the orange fish feeds on small fish that are either primary or secondary consumers. Besides this, the orange fish is eaten by dolphins and sharks which are at the top of the food chain and are quaternary consumers.
