Which if the following best describes the movement of energy in an ecosystem?

Which of the following best describes the movement of energy in an ecosystem? Energy is harnessed by producers, and available energy decreases with each trophic level transfer.

How do you describe the movement of energy in an ecosystem quizlet?

Energy flows through an ecosystem in a 1-way stream, from primary producers to various consumers. Energy is said to flow in a “1-way stream” through an ecosystem. … Pyramids of energy show the relative amount of energy available at each trophic level of a food chain or food web.

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.

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. In a given ecosystem, producers convert solar energy into 15,000kcal of chemical energy stored in organic compounds.

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

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.

How do energy move through an ecosystem?

Energy is transferred between organisms in food webs from producers to consumers. … This energy is available for higher order consumers. At each stage of a food chain, most of the chemical energy is converted to other forms such as heat, and does not remain within the ecosystem.

What describes the movement of energy and nutrients in an ecosystem?

Energy flow is the flow of energy through living things within an ecosystem. All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain. Each of the levels within the food chain is a trophic level.

Which of the following best describes the movement of energy?

Which of the following best describes the movement of energy in an ecosystem? Energy is harnessed by producers, and available energy decreases with each trophic level transfer.

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

Terms in this set (39) Which of the following best explains why decomposers in soils and water are important to ecosystems? They recycle nutrients.

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.

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

Gross primary productivity is the amount of carbon fixed during photosynthesis by all producers in the ecosystem. However, a large part of the harnessed energy is used up by the metabolic processes of the producers (respiration).

Which ecosystem has the lowest net primary productivity?

The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.

What is net primary productivity?

They show net primary productivity, which is how much carbon dioxide vegetation takes in during photosynthesis minus how much carbon dioxide the plants release during respiration (metabolizing sugars and starches for energy).

What equation best represents net primary productivity?

Net Primary Production (NPP) = GPP – RA The amount of organic carbon produced by plants that is not consumed by their own respiration. It is the increase in the plant biomass in the absence of herbivores.

What factors affect net primary productivity?

In addition to solar radiation, the main abiotic factors that affect rates of photosynthesis and NPP are water, temperature, carbon dioxide concentration, and nutrients.

Which of the following major storage reservoirs of carbon stored in the form of carbon dioxide is not represented in the diagram?

Which of the following major storage reservoirs of carbon, stored in the form of carbon dioxide, is not represented in this diagram? D: The ocean (Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean; the ocean stores large amounts of carbon dioxide.)
