The Energy Pyramid Producer – a plant that makes food

1st Consumer – an animal that eats that plant

2nd Consumer – an animal that eats that animal

The Energy Pyramid (cont.)I. No energy conversion is 100% efficient

A. 10% rule of thumb – only about 10% of the energy passes from one level to the next

B. There is more energy available at the bottom of the energy pyramid (producers) then at the top (consumers)

The Energy Pyramid (cont.)II. Size of organisms

A. As you travel up the pyramid organisms get larger

The Energy Pyramid (cont.)III. Humans

A. Humans started eating lower on the food chain to deal with increasing energy needs

The Energy Pyramid (cont.)IV. Facts

A. With the population increasing worldwide, humans need to do the following:

1. Improve agricultural techniques2. Eat lower on the pyramid3. Genetically modify plants (food)4. IDEAS???

B. It takes about 10 kg of grain to make 1 kg of beef (10% rule)
