As with virtually all habitats, a number of different biotic and abiotic factors affect temperate grasslands. Abiotic factors include the soil chemistry, temperature, winds, precipitation and pollution, while biotic factors include the plants, animals, bacteria, fungi and diseases in the habitat.Know More
The biotic factors affecting a grassland can change quickly. For example, a bacterial disease may spread through the local vegetation, drastically altering the species that can survive. Alternatively, an invasive weed could spread through the habitat, competing against the native flora. Animals may affect ecosystems even more quickly, as a swarm of insects may strip a grassland completely of food in a matter of days.
The biotic factors influencing a grassland may change as well, but most often, they occur over extended periods of time. This may allow the habitat to adapt to the changing conditions gradually. For example, erosion from rain and wind may gradually change the shape of the land. By contrast, pollution is an abiotic factor that may change a grassland very quickly. If humans cause pesticides, herbicides or insecticides to cover a grassland, the habitat may suffer immediate, long-term damage. Even substances such as fertilizers and antibiotics may cause an ecosystem to go into swift decline.Learn more about Biology
The abiotic, or non-living, factors that affect an ecosystem include the local temperature, light intensity, geology and presence of pollutants. Additionally, factors such as the pH of the soil and the types of gases that are dissolved in a body of water are non-living factors to which living organisms must adapt. The weather conditions of an area are abiotic factors that influence the functioning of ecosystems.Full Answer >
Abiotic factors are non-living things or conditions that affect or influence ecosystems and the organisms within the ecosystems. Abiotic factors play a huge role in which organisms survive in an environment, according to Dictionary.com.Full Answer >
Abiotic factors in the arctic tundra include frozen soil not far below the surface that is of poor quality. Strong winds are common, and there is very little rainfall, though there is usually enough moisture to grow some short plants.Full Answer >
Common abiotic factors include temperature, light, moisture and pH. In a standard ecosystem, abiotic factors represent any non-living elements of that system. Therefore, determining abiotic factors is specific to the ecosystem in question.Full Answer >
