Living components of an ecosystem The cycle of Energy

Energy Cycling Energy travels through an ecosystem It enters as sunlight and become low energy detritus. It passes through organism to organism. Many different organisms carry the same energy. It is passed by being eaten (consumed)

Decomposers Decomposers enter the energy cycle at nearly all levels. They consume dead organisms and intern are eaten. They recycle potentially wasted energy.

Primary producers Also called autrotrophs. Convert solar energy (sunlight) into chemical energy. May be plants algie or types of bacteria. Provide chemical energy to those who consume them.

1st order Consumers Consume primary producers. Called herbivores. Use only 10% of the energy provided by the plants.
