Energy Flows

What is biomass?

Biomass is the mass of all the living materials found in both plants nad animals.

Energy Flows

What is a pyramid of Biomass?

A pyramid of biomass is a way of representing the biomass of organismism at different stages in the chain.

Energy Flows

Name ways that energy is lost during a food chain

Eneegy is lost through faeces as not all food eaten is digested. Some of the energy is used in respirationand for life processes such as movement and growth.

3 of 14

Energy Flows

What is best short food chain or a long food chain? Why?

A short food chian because less energy is lost through the previously mentioned ways and therefore we can say that eating plants provides more energy then eating meat because it is the first stage on the chain.

Energy Flows

How can meat be artificialy created with more energy?

Meatcan be artificially created by not allowing animals to move therefore energy is not wasted through growth or movement and if there tempertures are kept constant then energy is not used keeping their tempertures correct.

Energy Flows

What are Detrius Feeders?

Detrius Feeders begin the process of decay by eating dead animals and plants and producing waste products. Decay is fastest when it is warm and wet.

Energy Flows

Explain areas of the carbon cycle

The carbon cycle happens in plants as they give off oxygen, which mammels breath in and convert to carbon dioxide that plants use. If an animal or plantshould die then their carbon would be recylced by detrius feeders . If anything is burned it gives of carbon dioxide, which is taken in by plants and when the plant dies detrius feeders recyle this crabon.
