The prairie community is dominated by the grass and vegetation cover. Thus the lower most trophic level in the prairie ecosystem are the short and tall grasses. They produce major source of biomass for the herbivores of the food chain. They consume the grasses can be designated as primary consumers of the food chain. Also the producers which are grasses which make up the large amount of biomass will provide a source of food for the consumers. They will receive 100 percent energy from the sun and they will utilize 90 percent of it to make their food by the process of photosynthesis.

Small intestine
Nutrients are absorbed into the bloodstream through small finger-like nodules on the wall of the small intestine called villi.
The small intestine is a long hollow tube situated between the stomach and the large intestine. It is the part of the digestive system where the end absorption of food occurs. The small intestine is divided into three distinct regions which are the duodenum, jejunum and ileum. The ileum region contains villi (small finger-like structures) which help to absorb digested food and nutrients such as vitamin B12 and bile acids.
