Sunlight, soil, water, and pollution, for example, are all important abiotic factors of an environment that affect life. The biotic environment, on the other hand, is composed of all the living organisms in an ecosystem, and includes factors such as disease, predators, prey, and human activity.
Abiotic factors are non-living components that influence the biotic or living organisms that thrive in a specific biome. The presence and amount of abiotic factors in the Amazon are essential to the cycle of life of plants, animals and the decomposition of once-living things. They also affect the adaptation of plants and animals in the rainforest biome.
