What do zooplankton feed on?
phytoplankton
How do zooplankton get food?
Phytoplankton get their energy directly from the sun using photosynthesis, just like plants. Zooplankton then feed on phytoplankton, and are then eaten by larger zooplankton, fish, larger fish, and so on. Plankton are at the base of a complex aquatic food web.
Are zooplankton autotrophic or heterotrophic?
Zooplankton are heterotrophs that get their energy from feeding on phytoplankton, bacteria, other zooplankton, or even non-living material in the ocean. Zooplankton include single-celled protists (that are sometimes referred to as microzooplankton).
What is the most abundant kind of zooplankton?
A very broad range of animals live their entire lives in the plankton and are referred to as holoplankton. Among these are the copepods, which are small (1-2 mm long) aquatic crustaceans, and are generally the most abundant zooplankton species (Figure 1).
What percentage of zooplankton poo reaches the bottom of the ocean?
Most of this carbon that is absorbed by the ocean later returns to the atmosphere (about 90 percent). The rest is recycled within the twilight zone, and just 1 percent falls to the sea floor.
Where does all the poop in the ocean go?
Chemicals are added to kill as many germs as possible. Then the treated water is released into a local river or even the ocean. If you live near the coast your treated sewage probably goes into the ocean. The treated sewage is cleaned to make sure that it does not cause environmental problems.
How much of the ocean is poop?
Why Scientists Just Ran Numbers on All The Fish Poop in The World’s Oceans. Fish poop is full of carbon, and the ocean is full of fish poop. A new study estimates up to 16 percent of all the carbon in the world’s oceans come from fish faeces, fish breath, and other fish excretions.
Do fishes poop?

Most of the time, you’ll barely notice this mucus coating because of what your fish eats. The mucus is stretched thin and you’ll see a mush similar in color to the pellets you feed. If your fish has not been eating, you will only see the mucus. This is the “stringy, white fish poop” in fish.
Do fish know they’re in a tank?
So they learn the tank, but they don’t really understand the tank. Fish don’t have much higher level thought, most of what they do is more instinctive than cognitive.
