Grass is the dominant vegetation in temperate grasslands. According to the University of California, climates with annual rainfall averages of 25 to 75 inches are home to temperate grasslands. Most of the rainfall occurs in late spring and early summer. Temperatures range from as low as 0 degrees Celsius in the winter to more than 25 degrees Celsius in the summer. Vegetation found in temperate grasslands varies according to rainfall.
"The biome is made up of great, rolling tracts of land comprising grasses, herbs and flowers. Shrub growth is virtually absent in the biome, while trees only grow along the streams and rivers. The annual rainfall these grasslands receive ranges between 10-30 inches - which is apt as more than it is likely turn these grasslands into forestlands, and less is likely to turn them into deserts. Grasslands, in fact, acts as a transition zone between the desert and the forest. They are known by different names in different regions." (Putunda, 2013)
Since the grasslands have such a steady flow of rainfall it is ideal for vegetation. When there is plenty of growing vegetation, it can make way for a large primary consumer population. The large number of consumers tend to be food for the other levels of consumers. All of the above of course are nutrients for decomposers. All of these parts working together make for a great cycle of life with in the ecosystem.
It seems like precipitation does not really have an effect on temperature. You can have a place dry and hot like the desert or wet and hot like the rainforest to even an ecosystem like the tundra which is both cold and dry. It does seem however to have an effect on plant and animal life which is great for the ecosystems ability to sustain life. (Forseth, 2012)
