|
State why biomass and energy are reduced at each successive stage of a food chain. |
Energy is lost by each animal through; excretion, keeping warm and movement. |
|
|
Explain why energy is transferred in movement and heating the surroundings. |
Energy is required for organisms to move and they use energy also to remain warm in the colder climates/seasons. |
|
|
Explain in detail why energy transfers by heating are particularly large in warm-blooded organisms (mammals and birds). |
Warm-blooded animals do not keep themselves warm by the heat of the sun, they use their own energy to remain warm. This means they need more energy to keep warm since they loose more than cold-blooded animals. |
