A deer eats 25kg of herbaceous material per day. The herbaceous material is approximately 20% dry matter(DM) and has an energy content of 10MJ. (kg DM^-1). Of the total energy ingested per day, 25% is excreted as undigested material. Of the 75% that is digested, 80% is lost to metabolic waste products and heat. The remaining 20% is converted to body tissue. How many MJ are converted to tissue on daily basis? Calculate the percentage of energy consumed that is converted to body tissue. Draw a schematic of energy balance.
