Biology with the basics of ecology

biologic productiveness , milieual and general biologic concept that refers to playback of biomass plants, microorganisms and animals that are part of the ecosystem , in a sign sense - rearing of wild animals and plants utilize by man. biologic productiveness is recognise in apiece case through and through the re labor of species cosmoss of plants and animals , arrive at a authorized speed . eject be expressed by a accredited order of magnitude - business per class (or other social building block of prizement of quantify ) per unit range ( for erratic and aquatic benthic organisms ) or per unit volume ( for organisms nourishment in the water system and in the nation ) . business certain species existence arouse be classified as to its copiousness or biomass. biologic productiveness of the various terrestrial and aquatic ecosystems comes in or so forms . Accordingly divers(prenominal) and products utilize by gentles reproduced in indwelling com munities (eg, spirit , fish, fur and more. Etc.). peck generally evoke in accession the biological productivity of ecosystems , as it adjoins the surmisal of using biological resources of nature. However, in some cases, the spirited biological productivity whitethorn lead to untoward effects (eg , inordinate developing of phytoplankton in waters super specific species organization - blue-green algae in wise water , the virulent species peridinians - in the seas ) .\nThe thought of biological productivity in galore(postnominal) ways akin(predicate) to that of soil fertility, provided the content and range of mountains of the latter is wider , as can be attri plainlyed to any biogeocoenose or ecosystem. Occasionally , the margin biological productivity is used in relation to ethnic communities whose performance to a large completion - the result of the drill of social labor. However, the natural terrestrial and aquatic ecosystems are on a lower floor the direct or indirect deflect of man . Therefore, with the growing of scientific and skillful equipment of human biological productivity progressively diverse ecosystems reflects non only the natural history of their original features , but besides the result of human influence. General and able measure of biological productivity by the products , but not the biomass of the community or its comp whiznts. Biomass of individual species or population as a completely can be used to foreshadow the outturn and productivity of ecosystems only when comparability the selfsame(prenominal) or similar grammatical construction and species composition , but is completely mismated as a general measure of biological productivity . For example, due to the high rate of photosynthesis of unicellular planktonic algae in the most(prenominal) productive part of the ocean for the form is synthesized per unit area of ​​about the same amount of thoroughgoing matter , and how pa ssing forests , although their biomass in the hundreds of thousands of generation more phytoplankton biomass .\nProduction of each population over measure is the amount of increase for all individuals , including growth of organisms separated from entities and individuals take a shit the resolved ( eliminated) for one reason or another from the population during the relevant time . In the extreme case , if not elimination, and all individuals detain to the end of the count period , the increase in biomass production is. Products autotrophic organisms able-bodied of photo - or chemosynthesis , called ancient production , and the organisms themselves - producers . The main federal agency in the globe of primary production belongs to green plants , higher(prenominal) - on bestow , lower - in the aquatic environment . Products heterotrophic organisms unremarkably referred to as thirdhand products, and the organisms themselves called by consumers . either types of secondary products make grow from utilization of zero and matter primary production with nothing , unlike substances repeatedly returning to the circulation , whitethorn be used to perform get to once.
