Lesson 4: Mass and Energy  Flow

Mass in the ecosystem

Biomass refers the weight or mass from living tissue

This can be any living tissue

• Plant

• Animal

• Fungal

• Bacterial

Mass Transfer

Mass gets transfered though the ecosystem.

Producers will take abiotic factors and make food.

Consumers will eat the producers

Any dead remains gets eaten by the decomposers

Energy in Ecosystsms

In an ecosystem energy is stored inside food.

All energy in an ecosystem comes from an inorganic source

Normally the sun

Energy Transfer

The transfer of energy is never 100% effective.

Some energy from an organism is lost due to heat through the metabolism of the organisms.

Producers will take in the suns light and convert 10% into stored energy. Consumers will digest 10% of the producers energy and use it in their bodies
