usually eat animal material (carnivores) |
|
|
predators |
secondary, tertiary |
|

decomposers |
feed on dead and decaying organisms |
|

Law of Conservation Matter |
Matter is neither created nor destroyed, can only be transferred from one place to another (must be recycled) |

|
|
the carbon cycle |
the continued availability of carbon in ecosystems depends on carbon cycling through the abiotic and biotic components of an ecosystem |
|
|
nitrogen cycle |
nitrogen gas is converted to nitrate which is taken in by plants. Heterotrophs obtain their nitrogen by feeding off other organisms |
|
|
parasitism |
exploitation - host is harmed, parasite benefits |
|
|
mutualism |
benefit off of each other |
|
|
commensalism |
one benefits, other remains the same |
