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
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 >
The abiotic factors present in a forest include precipitation, soil chemistry, temperature, water chemistry, sunlight and moisture level. All these factors have an affect on the living things in the forest ecosystem.Full Answer >
Abiotic factors in a tropical savannah include climate, air, weather, water availability, soil and fire. Topography is also an important abiotic factor and is regulated by elevations, slops and aspects.Full Answer >
