What is the difference between gross primary productivity and net primary productivity?

• Gross primary productivity includes energy used in respiration, net does not.

• Net primary productivity includes energy used in respiration, gross does not.

• Gross primary productivity is measured in kcal, net is measured in joules.

• There is no difference between the two.

What is net primary productivity?

• The total energy captured by photosynthesizers in an area.

• The energy stored by photosynthesizers after subtracting respiration losses.

• The energy used by herbivores in an ecosystem.

• The energy lost to the atmosphere during photosynthesis.

Which of the following factors does not directly affect net primary productivity?

• Temperature

• Soil nutrients

• Wind speed

• Water availability

How does net primary productivity differ from secondary productivity?

• Net primary productivity is the energy stored by plants, while secondary productivity is the energy stored by animals.

• Net primary productivity is the energy used by animals, while secondary productivity is the energy stored by plants.

• Net primary productivity is measured in joules, while secondary productivity is measured in watts.

• There is no difference between the two.
