How do you explain plankton to a child?
Plankton are drifting organisms that live in the surface layers of the ocean. They live in the top layer of the ocean, called the epipelagic zone. They are not strong enough to swim against ocean currents. The term is in contrast to nekton, who can control their movements.
What is plankton kid friendly definition?
definition: a mixture of very small plants and animals floating in fresh or salt water. Most kinds of plankton are microscopic. Plankton is an important food source for many animals that live in water.
What is a plankton simple definition?
Plankton are marine drifters — organisms carried along by tides and currents. Plankton are usually microscopic, often less than one inch in length, but they also include larger species like some crustaceans and jellyfish.
What are planktons short answer?
Plankton are the diverse collection of organisms found in water (or air) that are unable to propel themselves against a current (or wind). The individual organisms constituting plankton are called plankters.
Is plankton a plant or animal?
There are two main types of plankton: phytoplankton, which are plants, and zooplankton, which are animals. Zooplankton and other small marine creatures eat phytoplankton and then become food for fish, crustaceans, and other larger species.
Where does the word zooplankton come from?
The term zooplankton comes from two Greek words ‘zoo’ meaning animals and ‘plankton’ meaning drifter. Zooplanktons form an integral part of food chains in aquatic environments from freshwater to seas and oceans.
What kind of animals eat zooplankton plankton?
Plankton is also a major source of food. Zooplankton feeds on phytoplankton. In turn, fish and other larger animals eat the zooplankton. Many types of whale feed on zooplankton. The huge whales catch the tiny plankton by using a series of filters, called baleen, in their mouths.
What’s the difference between a zooplankton and a phyto?
‘Phyto’ refers to ‘plant-like’. ‘Zoo’ refers to ‘animal-like’. Phytoplanktons consist of diatoms, cyanobacteria, dinoflagellates, green algae, and coccolithophores. Zooplanktons consist of organisms like radiolarians, foraminiferans, and dinoflagellates, cnidarians, crustaceans, chordates, and molluscs.
How are zooplankton threatened in the future?
The biggest threats for the survival of zooplankton in the future are climate changes and increased amount of UV radiation (as a result of thinning of the ozone layer). Most animals that belong to the group of zooplankton are microscopically small, 0.01 to 0.16 inches long.
