Study Notes

The ocean is home to a diverse food web, where every living thing plays a role in the food chain, from tiny algae to enormous whales.

Apex predators are at the top of the food chain, with no natural predators, and contribute to the food chain when they die and their bodies feed phytoplankton.
Secondary consumers are eaten by tertiary consumers and need to consume a large amount of prey to gain energy, examples include larger fish like tuna and swordfish, and smaller whales and sharks.
Primary consumers eat phytoplankton, using the energy from it as fuel, and have developed ways to avoid predators, examples include small fish, turtles, and rays.

Phytoplankton, such as algae, corals, and bacteria, are primary producers that use sunlight to grow, similar to plants on land, and are at the bottom of the food chain.
Plankton, including krill and shrimp, are tiny crustaceans that eat phytoplankton and are primary consumers, being the first animals in the chain to eat something else.
