A rabbit has ingested 1000 kilocalories of grass. He egest 400 kc of waste, and uses 300 kilocalories of energy for cellular respiration and 100 kilocalories is lost as heat. Does this show the law of conservation?
yes the energy input is the same as the energy output
no the energy input is the same as the energy output
A rabbit has ingested 1000 kilocalories of grass. He egest 400 kc of waste, and uses 300 kilocalories of energy for cellular respiration and 100 kilocalories is lost as heat. What is missing from this equation?

100 kilocalories of biomass
200 kilocalories of biomass
200 kilocalories of heat loss
200 kilocalories of cellular respiration
