Energy Flow in Ecosystems. Components of an Ecosystem. living and non-living things interact with each other in an ecosystem biomass – total mass of all living matter in an area abiotic factors – non-living things biotic factors – living things. Abiotic Factors.
The four major abiotic components are: a. climate b. soil, dead material, and rock c. topography d. natural disturbances
Biotic factors are anything that is living: a. plants b. animals c. microscopic organisms
Once an organism dies, decomposers take over and break down the material it was made of
These nutrients are put back into the soil
Plants then use those nutrients along with sunlight to recycle that energy back into the food chain
Composting – helping the natural decomposition process break down waste
Using a compost bin, we can recycle food scraps and return those nutrients to the soil
