Q

Can something be 100% efficient

A

No bc friction causes heat, which causes you to lose enegry bc it “goes away”

Q

What are the 4 steps that biogeochemical cycles usually have?

A

1) Producers incorporate chemicals from the abiotic reservoirs into organic compounds
2) Consumers feed on the producers, incorporating some of the chemicals into their bodies
3) Both producers and consumers release some chemicals back into the environment in the form of waste products
4) Decomposers break down complex organic molecules in detritus

20
Q

What are the 2 main types of biogeochemical cycles?

A

Local and Global Cycles

21
Q

Local Cycle

A

A cycle whose nutrients can only be cycled in a local environment

22
Q

Local Cycle example

A

an example is the soil being the main reservoir for nutrients in a cycle

23
Q

Local Cycle

A

A cycle whose nutrients can only be cycled in a local environment

24
Q

Global Cycle

A

cycles whose nutrients can be cycled with the same nutrients in different environments

25
Q

What form of chemicals is usually cycled globally

A

gaseous forms of chemicals

26
Q

Global Cycle example

A

Carbon because the carbon a plant acquires from the air may have been released into the atmosphere by the respiration of an organisms on a different continent
