5.2 Energy transfers
The biomass lessens as you go up the food chain because;
Ø Herbivores cannot digest all of a plant. Undigested parts are removed from the body through faeces.
Ø Animals and plants respire loosing energy through breathing and photosynthesis.
Ø Animals and plants lose energy through growing.
Ø Movement of animals takes away a large amount of energy because it transfers to kinetic + thermal energy.
Ø Plants, animals use energy to keep their bodies at the same temperature.
