What is the role of abiotic factors in the formation of biomes? Solution A biome is a large terrestrial region characterized by a specific type of climate and dominant plant life. There are a variety of terrestrial biomes contributing to the biodiversity on the earth. The living components of a biome include the organisms with life such as plants, animals, microbes and all living organisms. The non living components or abiotic factors include the components without life such as water, air, nutrients, heat and solar energy. For example, biomes like tropical rain forests are found at the equator with hot, moisture air rises dumping the moisture in the land. These forests have warm temperatures, high humidity and heavy rain fall daily. The forests are dominated by broad leaf ever green plants and much of animal life specifically large insects, bats and birds are abundant. Tree climbing animals and decomposers are heavily populated in tropical rain forests. These forests show great biodiversity with suitable climatic conditions for survival of all type of animals. The abiotic factors such as warm temperatures, moist air and rainfall daily keep the vegetation of the forest growing to provide nutrition for all kinds of organisms live in the biome. The sunlight helps the plants to synthesize nutrients and to provide them to plant dependent organisms. Thus, abiotic factors like temperature, sunlight, air and nutrients influence the growth, reproduction and survival of organisms in the ecological food chain in a biome..
