Climate is an abiotic factor - think about how many individual abiotic factors make up something as large as a climate. Natural disasters, such as earthquakes, volcanoes, and forest fires, are also abiotic factors. These types of abiotic factors certainly have drastic effects on the ecosystems they encounter.
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.
