Biotic and Abiotic Components of EnvironmentNatural environment includes all the living and non-living components occurring naturally on Earth. The biological components of the ecosystem that is the biotic components interact with the physical entities (abiotic components). The scientific study of the interaction of biotic community with each other and with abiotic components is known as Ecology.

Biotic components are the living things that shape an ecosystem. A biotic factor is any living component that affects another organism, including animals that consume the organism in question, and the living food that the organism consumes. Biotic factors include human influence.
Biotic components are contrasted to abiotic components, which are non-living components of an organism's environment, such as temperature, light, moisture, air currents, etc.
Biotic components usually include:
- Producers, i.e. autotrophs: e.g. plants; they convert the energy (from the sun, or other sources such as hydrothermal vents) into food.
- Consumers, i.e. heterotrophs: e.g. animals; they depend upon producers for food.
- Decomposers, i.e. detritivores: e.g. fungi and bacteria; they break down chemicals from producers and consumers into simpler form which can be reused.

Answers:Transpiration from the leaves of plants have a cooling effect and raise the humidity levels within a forest. The leaves falling to the ground and decomposed increases the nutrient levels in the soil, improves water retention and helps insulate the soil against freezing temperatures. The tree canopy helps moderate the soil temperature and decreases the evaporation of water from the soil. The root systems of plants slows soil erosion from wind and water.
Answers:Pollution (human activity) causes a change in climate (abiotic component) which causes glaciers to melt (abiotic) and polar bears to die (biotic). Hope this helped!
Answers:The earth has different environments / habitats, but I don`t know what d environment should be. Might be you find, what you are looking for, on this site with the best known biomes: http://www.enchantedlearning.com/biomes/ Abiotic components are the nonliving components of the biosphere. Chemical and geological factors, such as rocks and minerals, and physical factors, such as temperature and weather. http://www2.pwsd76.ab.ca/biodiversity/photo.htm Biotic factors are those factors which are living > animals, plants, decomposers, including fungi and bacteria. Biotic factors are rather specific to each biome, but in abiotic components weather is weather and minerals are minerals, they are more generalized.
Answers:Nitrogen fixing bacteria can convert nitrogen in the atmosphere into nitrates. (Biotic factor-bacteria...abiotic factors-nitrogen gas in the air and nitrates in th soil) In this case, the bacteria can affect the amt of nitrates in the soil as well as, to a lesser extent, the nitrogen in the air. Two other similar bacteria are nitrifying bacteria (which convert nitrogen cmpds into nitrates) and denitrifying bacteria (which convert nitrogen cmpds into nitrogen gas) All animals also contribute to the amount of carbon dioxide in the air by respiration. If you want to take it to the extreme, you probably can say that in forests (and even streams in which eutrophication is an issue) the taller plants affect the amount of light available to the smaller/shorter plants beneath. Temperature of an area (eg in a rainforest vs a dessert) is affected by the degree of sheltering from trees. I can think of a bunch of similar examples but I don't want to bore you with too many words. l.o.l. Hope this helped!
