Typically, zooplankton accumulate higher concentrations of DDT in their bodies compared to small fish. This is due to a process called biomagnification, where toxins like DDT become more concentrated at each level of the food chain. Zooplankton, being at the base, absorb DDT from the water and sediments, and when small fish consume them, the concentration of DDT increases in the fish. Thus, while both may contain DDT, small fish generally have higher levels due to their position in the food web.

What do perch fish eat?
Perch fish are carnivorous and primarily feed on zooplankton, insects, small fish, crustaceans, and aquatic invertebrates. They are opportunistic feeders and will consume whatever prey is most readily available in their environment.
What fish does a Garibaldi eat?

Why is the ocean food chain pretty long?
The ocean food chain is pretty long and it contains about 10 links. The primary consumer is the zooplankton, which is the smallest animal in the world, the size of a tiny pencil dot but still can be seen with a naked eye and the apex predator is the whale, which is the novenary consumer. The blue whale is the biggest animal in the world and most scientists estimated that about quintillions of zooplanktons can make up the blue whale size. Ocean Food Chain: Sun>Seaweed>Zooplankton>Plankton>Krill>Shrimp>Small Fish>Medium Fish>Big Fish>Shark>Whale Trophic Level Classification: Seaweed~Producer Zooplankton~Primary Consumer Plankton~Secondary Consumer Krill~Tertiary Consumer Shrimp~Quaternary Consumer Small Fish~Quinary Consumer Medium Fish~Senary Consumer Big Fish~Septenary Consumer Shark~Octonary Consumer Whale~Novenary Consumer or Apex Predator The whales usually eat sharks as their normal food diet. The whale is the ocean's apex predator, not the shark.
Do zoo plankton have legs?
No, zooplankton do not have legs. They are typically small, often microscopic, marine animals that drift in the water column and rely on ocean currents for movement. They may possess structures like cilia or appendages for propulsion, but not true legs.
What is the jellyfishes main diet?
Most jellyfish are passive drifters that feed on small fish and zooplankton that become caught in their tentacles. Jellyfish also eat small animals such as shrimps. Some of the animals Jellyfish eat are microscopic, too small to be seen by the human eye. Jellyfish also eat other Jellyfish of other species. They catch their prey by using nematocysts, small stinging organs present in the tentacles and oral arms.
