Study Notes
Ocean Food Chain
- 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.
Food Chain Hierarchy
- 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 and Primary Producers
- 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.
