The Science of Tropical Savannas

Savannas are part of the Grassland biome, and are generally found in regions dominated by the "Wet-Dry Climate." Tropical Savannas encompass almost one half of the entire continent of Africa as well as many parts of Australia, India, Mexico, and South America. The Tropical Savannas in Australia take up over one-third of the country, and provide natural resources that contribute much of the money that supports the national economy. The Climate is the most important factor in creating a savanna. Tropical Savannas are always found in hot weather with a mean temperature of among eighty-five to ninety degrees Fahrenheit, where the annual rainfall is from about twenty to fifty inches per year. Yet the rain

A few notable species of trees in the savanna are Acacia tree and the baobab tree. Plants in the savanna have to adapt to the long dry season in a number of ways. The Baobab tree stores water in its trunk , drawing on the moisture and then go into a state of dormancy. Grasses turn brown and trees turn their leaves to reduce transpiration. Transpiration is the loss of water by evaporation through pores in the shoot system of the plant. These plants need to adapt because if they don't then their species would eventually become extinct. In every biome the Abiotic and biotic factors interact with one another. The sunlight helps with the photosynthesis of the trees and the vegetation who then take in the carbon dioxide in the air, and produce oxygen for the animals and other oxygen in taking organisms. The soil is also a breeding ground and living shelter for many small creatures. These creatures such as the earthworm and African termite and beetle need the soil to shield and conceal them. Energy, the capacity to do work and transfer heat is necessary to obtain, in order to survive in any environment. Energy comes in many forms. The sun is the main origin of energy. It provides the nutrients needed for plant growth or the producers, which provides food for the primary consumers, the herbivores. The carnivores being the secondary consumers feed on the primary
