abiotic factors definition biology
Back to Top. Abiotic facotrs are the non-living components of the ecosystem. The chemical, geological factors like soil, minerals, rocks and physical factors like temperature, wind, water, sunlight are defined as abiotic factors. The abiotic factors effect the ecosystem and play a vital role in the biology of the ecosystem. Biotic and abiotic factors affect the organisms in an ecosystem. Biotic factors may include things like predation, disease, competition, parasitism, consumption, and symbiosis. And certainly abiotic factors, like the weather, can also impact living things. Abiotic components are and ecological factor that acts of living components during any part of their life. Abiotic factors are the factors that are either physical or chemical factors that are the characteristic of the environment being studied. Abiotic factor examples include temperature, wind speed, and humidity. An abiotic factor is any component that is not a living organism that affects the organisms in the ecosystem. Abiotic factors related to climate include temperature, wind speed, humidity, amount of sunlight, and shade. Abiotic factors can also be in the soil and include things such as pH and mineral content. Biotic and abiotic factors both impact ecosystems by limiting the quantities of the organisms that can live there. The carrying capacity, or the largest number of individuals of a species in a particular ecosystem, is set by the ever-changing play between biotic and abiotic factors. The biotic factors of an ecosystem are all the living organisms that affect other organisms in an ecosystem and include animals, plants, microorganisms, dead organisms, and even animal waste. The parts of an ecosystem that are not alive, like rocks, weather, and sunlight, are the abiotic factors. Population (level of organization) a group of individuals that belongs to the same species and live in the same area. Community (level of organization) an assemblage of different populations that live together in a defined area. Anything living in an ecosystem is a biotic factor. This is in contrast to abiotic factors, which are non-living factors of an ecosystem. Examples of biotic factors include and are not limited to, mammals, birds, reptiles, trees, grasses, microorganisms, flowering plants, fish, bacteria, and so forth. 020 - Biotic and Abiotic Factors. Biotic and Abiotic Factors. Paul Andersen differentiates between biotic and abiotic factors. He explains how both abiotic and biotic factors can affect organisms at the level of the cell, the population and even the ecosystem. The complexities of biofilms, predator-prey relationships, and food webs are given as illustrative examples. Biotic factors, as well as abiotic factors, have more to do with how those parts of an ecosystem affect one another than the specific living or non-living thing itself. Biotic factors in an ecosystem are the living things that affect other living things in that ecosystem. Competition, consumption, predation, parasitism, disease, even symbiosis are all ways a biotic factor could have an effect on the other creatures they encounter.
