At the bottom of the food chain are microscopic plants and at the top are well-known predators like sharks and seabirds. Producers create their own food. These single-celled, microscopic plants float on top of the ocean, take in energy from the sun and use it to convert carbon dioxide and other nutrients into carbohydrates, which nourish other ocean life. Other types of phytoplankton are technically protists like diatoms and algae. They make up 95 percent of the primary producers on earth. Zooplankton are small, floating animals. They include fish larvae, jellyfish, microscopic copepods and small, bottom-dwelling animals.

Sharks play a very important role in the oceans in a way that an average fish does not. Sharks are at the top of the food chain in virtually every part of every ocean. In that role, they keep populations of other fish healthy and in proper proportion for their ecosystem. How do sharks keep the oceans healthy? Sharks have evolved in a tight inter-dependency with their ecosystem. They tend to eat very efficiently, going after the old, sick, or slower fish in a population that they prey upon, keeping that population healthier.

But the sea is so vast that a million or more as yet unknown species may live in its waters. Most of these aquatic species are tied together through the food web. The foundation of the sea's food chain is largely invisible.

Sharks' Role in the Oceans
Found in the North Palace at Ninevah, stone panels depicting the Royal Lion Hunt of the last Assyrian king, Ashurbanipal, are as violent as any video game: A female lion flies upside down, arrows protruding from her back and belly. Beneath her, a male rears back, arrows piercing his nasal passages while another male drags his hindquarters behind him. The panels are two-and-a-half thousand years old, and the story they tell is nearly over. The tiger is near extinction. While no one disputes the importance of photosynthesis and nutrient cycling, experts on predation have become increasingly convinced that ecosystems are ruled from the top.
The Crucial Role of Predators: A New Perspective on Ecology
Sharks play an important role in the ocean food chain. If sharks decline to seriously low numbers, commercial fisheries could be threatened. In Australia, one lobster fishery is threatened, because the declining number of sharks cannot control the lobster eating octopuses. Photo by J. Maragos Photo by J. Sharks reproduce similar to mammals in that they have a low rate of reproduction and do not spawn like fish which have a thousands or millions of larvae, hoping for a certain percentage to sustain the species.
Apex predator. Great white sharks are apex predators, on top of their food chain. Sharks are at the top of the food chain. Phytoplankton or aquatic vergetation. I dont know what the food chain is but i know what the diet is. Piranha are up on the food chain.
