Krill primarily eat phytoplankton, microscopic, single-celled plants found near the ocean's surface.
Krill's Diet: A Closer Look
Krill are small crustaceans that form a vital part of the ocean's food web. Their diet consists mainly of:
- Phytoplankton: As the primary food source, phytoplankton are microscopic plants that produce their own food through photosynthesis. This process requires carbon dioxide and sunlight.
Phytoplankton and Photosynthesis
Phytoplankton, like plants on land, uses photosynthesis to create energy. This involves:
- Absorbing sunlight.
- Taking in carbon dioxide.
The Importance of Krill
Krill play a crucial role in the marine ecosystem. They are a major food source for larger animals, including whales, seals, penguins, and fish. Because krill feed on phytoplankton, they transfer the energy produced by these tiny plants up the food chain.
