1. Zooplanktons
2. Small fish
3. Sea urchins
4. Crustaceans
1. Zooplanktons: Zooplanktons derive their energy from the sun indirectly by consuming phytoplanktons (single-celled photosynthetic organisms) and other smaller zooplanktons. They are considered herbivores.
2. Small fish: Small fish consume zooplanktons, other small fish, and marine invertebrates. They can be categorized as omnivores or even carnivores depending on their specific diet.
3. Sea urchins: Sea urchins primarily graze on algae and other plant material found on rocks and other surfaces. They are herbivores, consuming primarily plant-based food.
4. Crustaceans: Crustaceans, which include animals like shrimp, crabs, and lobsters, have a varied diet. Depending on the specific species, they can be herbivores, omnivores, or even carnivores. Some crustaceans feed on detritus and plant matter, whereas others prey on smaller animals.
