Who eats phytoplankton?


Phytoplankton produce their own food by lassoing the energy of the sun in a process called photosynthesis. So for sunlight to reach them they need to be near the top layer of the ocean. So must zooplankton which feed on the phytoplankton. Plankton have evolved many different ways to keep afloat.

Are zooplankton consumers?

Zooplankton are the animal-like primary consumers of plankton communities. In turn zooplankton then become food for larger secondary consumers such as fish. Zooplankton include microscopic and macroscopic organisms.

What organisms do phytoplankton eat?

Plankton are microscopic living things that drift around in the world’s oceans. Some live like plants and are called phytoplankton. They make food from simple chemicals and live in the oceans’ upper zone to get sunlight. The phytoplankton are eaten by swarms of tiny animal plankton called zooplankton.

What do krill eat?


Antarctic krill are filter feeders that eat tiny phytoplankton (pelagic algae). They use their small hair-like legs to filter out these microscopic algae that bloom in the nutrient-rich waters around Antarctica. These blooms are densest at the ice edge so Antarctic krill are often also densest near that system.

Are Penguins omnivores?

Penguins are carnivores they eat only meat. Their diet includes krill (tiny crustaceans) squid and fish. Some species of penguin can make a large dent in an area’s food supply.

Does plankton eat algae?

What is phytoplankton food web?

The food web

The microalgae are also nourishment for krill and zooplankton. Fish then get sustenance from the organisms that have fed on the phytoplankton including baleen whales which strain the plankton out of the water and into their mouths.

Does phytoplankton eat?

What is phytoplankton zooplankton?

Difference Between Phytoplankton and Zooplankton

Phytoplanktons are plants while zooplanktons are animals this is the main difference between them. Other Crustaceans krills are examples of zooplanktons algae and diatoms are examples of phytoplanktons. These two types of planktons float on water surfaces.

Do krill eat zooplankton?

Krill are considered an important trophic level connection – near the bottom of the food chain. They feed on phytoplankton and (to a lesser extent) zooplankton yet also are the main source of food for many larger animals.

Are zooplankton Autotrophs or Heterotrophs?

Overview. Zooplankton are the animal component of the planktonic community (“zoo” comes from the Greek word for animal). They are heterotrophic (other-feeding) meaning they cannot produce their own food and must consume instead other plants or animals as food. In particular this means they eat phytoplankton.
