The food chain is the sequence of organisms through which food and its contained energy pass in an ecosystem with members at one step becoming the food of the later step of the sequence. Phytoplankton is the primary producers that trap solar energy for food production during the process of photosynthesis which is then used by the small free-floating aquatic animal i.e., zooplanktons.

Phycol., 1990, (26), 278-288. And creatures at the bottom of the food chain known as phytoplankton had declined globally, according to observations from.
For plankton, both quantity and quality - in terms of nutrients - affect life up the food Researchers found that the extirpation of large fish has even impacted the base of the food chain, and caused a decline in phytoplankton, the microorganisms in charge of fueling the entire marine food web. What are phytoplankton ? Phytoplankton are microscopic plants that live in the ocean. These small plants are very important to the ocean and to the whole planet! They are at the base of the food chain. Many small fish and whales eat them.

In a balanced ecosystem, they provide food for a wide range of sea creatures. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Phytoplankton are a key food item in both aquaculture and mariculture. Both utilize phytoplankton as food for the animals being farmed. In mariculture, the phytoplankton is naturally occurring and is introduced into enclosures with the normal circulation of seawater. In aquaculture, phytoplankton must be obtained and introduced directly.

Hence, phytoplankton is a component of pond ecosystem present at the first trophic level. Zooplankton occupies the second trophic level.
Phytoplankton are autotrophs, so they make their own food and are producers. They are eaten by zooplankton, which are consumers. America has a few hidden gems in the fast-food world, and you might have walked right past them without knowing.

Phytoplankton Ecology . Why people should care about phytoplankton ecology. They provide the basis for much of the aquatic food chain; Substantial impact on global environmental balance Global phytoplankton primary productivity is estimated at 10 15-10 16 g carbon/year; They can form nuisance blooms Sheer abundance can lead to anaerobic
Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow. Phytoplankton are the foundation of the marine food chain. All other marine creatures depend on them directly or indirectly for food or oxygen . Krill , for example – arguably the most important link between plankton and larger marine creatures – is heavily dependent upon phytoplankton for its main source of food.

Phytoplankton are autotrophs, so they make their own food and are producers. They are eaten by zooplankton, which are consumers.
The zooplankton are then eaten in vast numbers by fish and other marine creatures. Plankton are the first link in the oceanic food chain, vital to all ocean life.
