What is the niche of plankton?
The fundamental niche is the full set of environmental conditions under which a species can persist, and for phytoplankton, this is typically defined in the laboratory.
What is the role of plankton in aquatic ecosystems?
Marine plankton, found in all ocean ecosystems, play a critical role in maintaining the health and balance of the ocean and its complex food webs. The oxygen, nutrients, and biomass they produce also sustain terrestrial life—from the food we eat to the air we breathe.
What is zooplankton niche?
The zooplankton community is an important element of the aquatic food chain. These organisms serve as an intermediary species in the food chain, transferring energy from planktonic algae (primary producers) to the larger invertebrate predators and fish who in turn feed on them.
What are niches in the ocean?
The fundamental ecological niche is the environment that permits sustained growth of a species (Hutchinson 1957), that is, it is a hypervolume in environmental space defined by favorable conditions in critical physical and chemical factors such as temperature, nutrients, and light.
What does plankton need to survive?
Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water.
What is plankton and why is it important?
Phytoplankton are some of Earth’s most critical organisms and so it is vital study and understand them. They generate about half the atmosphere’s oxygen, as much per year as all land plants. Phytoplankton also form the base of virtually every ocean food web. In short, they make most other ocean life possible.
What is zooplankton do?
How do plankton adapt to their environment?
Plankton avoid sinking through increased surface area. Flattened bodies and appendages, spines, and other body projections slow sinking by adding surface area without increasing density. Some phytoplankton also avoid sinking by forming large chains.
Are plankton consumers or producers?
Primary producers — including bacteria, phytoplankton, and algae — form the lowest trophic level, the base of the aquatic food web. Primary producers synthesize their own energy without needing to eat.
