Full Answer

An environmental or non-living factor that influences the ecosystem is an abiotic factor. Tropical grasslands or savannahs are very dry during winters, but never get too cold. The summer season is very humid due to rainfall.

Climate determines the type of animals that survive in an ecosystem; it’s the most important abiotic factor. The average climate is normally warm all year. Tropical savannahs fall neither in the desert category nor rain forest category because rainfall is just enough for vegetation in summer. Rainfall is 15 to 20 inches, and summers are notably hot.

Fire is a distinctive characteristic of this region. If there were no fire, tropical savannahs would be just like tropical forests. Air is a basic necessity of life for any ecosystem. Soil is very fertile and porous in summer season due to rainfall and grazing of different animals.

Water is abundant in summer and causes small plants to flourish. In winters, soil is very dry, and there is no vegetation. The average temperature is around 70 degrees Fahrenheit.
