Ecosystem ecology. the study of energy flow and the cycling of chemicals among the various biotic and abiotic components in an ecosystem ... photosynthesis by plants and phytoplankton removes substantial amounts of atmospheric CO2 each year; this quantitiy is approximately equaled by CO2 added to the atmostphere through celular respiration by ...
Zooplankton are heterotrophic organisms that consume phytoplankton. According to the biochemist Alfred J. Lotka, this makes them secondary consumers, as their energy is obtained from consuming the primary producers of energy in their environment.
In the ecosystem, phytoplankton functions as producers. Phytoplanktons are marine plants and are food for aquatic animals. They are autrotrophic components. Hope this answers the question. Have a nice day. Feel free to ask more questions.
Diagram of two food chains showing producers: plants and phytoplankton. The correct answer is C. Producers. An ecosystem consists of a group of organisms that all interact with one another in some way and interact with the physical environment. A hallmark of ecosystems is the presence of food chains.
What Roles Does Plankton Play in the Ecosystem? Plankton exist near the bottom of the ocean's food chain and provide nutrition for whales, shrimp, snails and jellyfish. Plankton also play an important role in the carbon cycle by removing inorganic carbon dioxide due to photosynthesis.
Phytoplankton is the base of several aquatic food webs. In a balanced ecosystem, they provide food for a wide range of sea creatures including whales, shrimp, snails, and jellyfish. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and ...
Phytoplankton Definition. Phytoplankton are a type of microscopic plankton capable of photosynthesis found in oceans, seas, and freshwater, and an essential component of aquatic ecosystems. Phytoplankton can range in size and shape, and since they are photosynthesizing autotrophic organisms, they inhabit waters exposed to sunlight.
Phytoplankton. Phytoplankton are the main contributors to total primary production in marine ecosystems (Duarte and Cebrián, 1996) and support strongly size-structured food webs where most predators are larger than their prey (Boudreau et al., 1991).
Marine ecosystem productivity depends on the amount of primary production by phytoplankton, unicellular photosynthetic algae and cyanobacteria suspended in the water column that form the base of the marine food web. Measurements of the primary photosynthetic pigment, chlorophyll a (CHL), are commonly used as a proxy for phytoplankton biomass.
