🗑
|
||||
| Water Cycle | The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

||||
| Nitrogen Cycle | The series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms.
🗑
|
||||
| Phosphorus Cycle | A biogeochemical cycle that describes the movement through the lithosphere, the hydrosphere, and biosphere.
🗑
|
||||
| Abiotic Factors | Non-living factors that impact the ecosystem.

🗑
|
||||
| Decomposer | an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
🗑

|
||||
| Secondary Consumers | Omnivores and herbivores.
🗑
|
||||
| Tertiary Consumers | Carnivores.
🗑
|
||||
| Food Pyramid | A graphic representation of predatory relationships in the food chain, in which various forms of life are shown on different levels, with each level preying on the one below it.
🗑
|
||||
| Symbiosis | interaction between two different organisms living in close physical association, typically to the advantage of both
🗑
|
||||
| Mutualism | the doctrine that mutual dependence is necessary to social well-being.
🗑
|
||||
| Parasitism | the practice of living as a parasite in or on another organism
🗑
