- Secondary consumers
- Phosphorus cycle
- Net Primary Productivity (NPP)
- Sulfur cycle
- a Cyclic movement of phosphorus in different chemical forms from the environment to organisms and then back to the environment
- b Process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches.
- c Rate at which all the plants in an ecosystem produce net useful chemical energy; equal to the difference between the rate at which the plants in an ecosystem produce useful chemical energy (gross primary productivity) and the rate at which they use some of that energy through cellular respiration. Compare gross primary productivity.

5 True/False questions
Hydrologic (water) cycles → Continuous movement of water on, above and below the surface of the Earth.
Fermentation → A catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end product, such as ethyl alcohol or lactic acid.
Nutrient (biogeochemical) cycles → The pathways by which chemicals circulate through ecosystems that involve both living (biotic) and nonliving (geological) components.
Carbon cycle → Cyclic movement of carbon in different chemical forms from the environment to organisms and then back to the environment.
Organisms → An animal or plant with organs that function together to maintain life; a living thing; anything that resembles a living thing in structure or function
