Biology B1.5.1 Energy in Biomass

Biomass is mass of living material. It decreases along a food chain.

An example:

Only 10% of the sun's energy is used for growth in a plant. The rest is either reflected into the atmosphere, passed through the leaf or heats the leaf up.

Again., only 10% of energy from the plant or other animal is used for growth. The rest is lost in respiration, in waste products, in heat to the atmosphere, in movement, and when the animal dies.
