Categories of plants, "Useful" and "Harmful," etc., are yet another well-known example. Indeed, in recent years there has been a vogue usage of the term ethnotaxonomy limiting it to ethnobotany and ethnopharmacology , because of the "rediscovery" of the medicinal and commercial value of plants disclosed by examining the botanical ...
Planktology is the study of plankton, various small drifting plants, animals and microorganisms that inhabit bodies of water. Planktology topics include primary production, energy flow and the carbon cycle. Plankton drive the "biological pump", a process by which the ocean ecosystem transports carbon from the surface euphotic zone to
The plankton can either be collected from a body of water or cultured, though the former method is seldom used. Phytoplankton is used as a foodstock for the production of rotifers, [62] which are in turn used to feed other organisms. Phytoplankton is also used to feed many varieties of aquacultured molluscs, including pearl oysters and giant clams.
Phytoplankton; Zooplankton; However, there is a simpler scheme that categorizes plankton based on a logarithmic size scale: Macroplankton (200–2000 μm) Micro-plankton (20–200 μm) Nanoplankton (2–20 μm) This was even further expanded to include picoplankton (0.2–2 μm) and fem-toplankton (0.02–0.2 μm), as well as net plankton ...
Classification of fungal races can be difficult because host plants' responses to particular populations of fungi can be affected by humidity, light, temperature, and other environmental factors; different host plants may not all respond to particular fungal populations or vice versa; and identification of genetic differences between ...
Zooplankton feed on bacterioplankton, phytoplankton, other zooplankton (sometimes cannibalistically), detritus (or marine snow) and even nektonic organisms. As a result, zooplankton are primarily found in surface waters where food resources (phytoplankton or other zooplankton) are abundant. Zooplankton can also act as a disease reservoir.
Freshwater phytoplankton is the phytoplankton occurring in freshwater ecosystems. [1] It can be distinguished between limnoplankton (lake phytoplankton), heleoplankton (phytoplankton in ponds), and potamoplankton (river phytoplankton). [2] [3] They differ in size as the environment around them changes. They are affected negatively by the change ...
