Which of the following best describes gross primary productivity in an ecosystem quizlet?

Which of the following best describes gross primary productivity in an ecosystem? Gross primary productivity is the total amount of solar energy captured by producers through photosynthesis over time.

Which of the following best describes the net primary productivity of an ecosystem quizlet?

Which of the following best describes the net primary productivity of an ecosystem? Net primary productivity is the amount of energy lost through respiration by producers subtracted from the gross primary productivity of an ecosystem. You just studied 13 terms!

What is the gross primary production of an ecosystem?

Gross primary production (GPP) is the total amount of carbon dioxide “fixed” by land plants per unit time through the photosynthetic reduction of CO2 into organic compounds.

Which of the following best explains why decomposers in soils and water are important to ecosystems?

Explanation: The main role of the decomposer in any ecosystem is to recycle nutrients once organisms die and recycle nutrients in waste. These nutrients are then released into the ecosystem and are available again for use.

What is net primary productivity quizlet?

net primary production. the available energy in the form of organic material that is available for transfer to the next level of the food chain. This is equal to the gross primary productivity of an organism minus the energy used by that organism. niche. the role an organism has in an ecosystem.

Which of the following best describes gross primary productivity?

Which of the following best describes gross primary productivity in an ecosystem? Gross primary productivity is the total amount of solar energy captured by producers through photosynthesis over time.

Which of the following best describes the net primary productivity?

Which of the following best describes the net primary productivity of an ecosystem? Net primary productivity is the amount of energy captured by producers through photosynthesis over time.

What does gross primary and net primary production mean?

Gross primary production (GPP) is the total rate at which material is produced and net primary production (NPP) is the rate at which material is accumulated in excess of respiration. In other words, NPP is GPP minus respiration. … Net primary production is directly related to ecosystem conditions.

What is an example of gross primary productivity?

For example, studies of an oak-pine forest in New York found that the total fixation of solar energy by vegetation (i.e., the gross primary productivity) was about 48.1-thousand kilojoules per hectare per year. This fixation rate was equivalent to less than 0.01% of the input of solar radiation to the forest.

Why gross primary productivity is important?

The productivity of the primary producers ( gross primary productivity ) is important to ecosystems because these organisms bring energy to other living organisms.

Which of the following best explains the primary role of decomposers in ecosystems decomposers?

Why are decomposers an important part of ecosystems? They break down dead organisms to return nutrients to the soil. They produce their own food for survival. They play a role in preventing weathering and erosion.

What is the process of primary productivity?

Primary productivity is the process by which organisms make their own food from inorganic sources. … These organisms are known as autotrophs, since they can use inorganic substrates and solar energy to carry out metabolic processes and build cellular material.

Which of the following best describes why decomposers are needed in an ecosystem?

Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

What is the primary productivity of an ecosystem quizlet?

Terms in this set (12)

Primary productivity is the rate at which energy is converted by photosynthetic and chemosynthetic autotrophs to organic substances.

What is the definition of gross primary production quizlet?

Primary production is the amount of light energy converted to chemical energy by autotrophs in a given time period. … Gross primary production is the amount of energy from light converted to chemical energy per unit of time.

How do you calculate gross secondary productivity?

​Gross secondary productivity(GSP): is gained through absorption in consumers. Net secondary productivity(NSP): The gain by consumers in energy or biomass per unit area per unit time remaining after allowing for respiratory losses. Secondary productivity: NSP = GSP – R.
