course hero which of the following statements about biogeochemical cycles is true?

Which of the following statements are correct about the biogeochemical cycles?

[b] Regarding biogeochemical cycles, statement (i), (ii), and (iv) are correct. Biogeochemical cycle is the flow of chemical elements and compounds between living organisms and the physical environment.

Which of the following has the greatest effect on the rate of chemical cycling within an ecosystem?

The rate of decomposition, the right of big composition has the greatest effect. It's the great test you think, on the rate of on the the rate of chemical cycling chemical cycling in an because the steam thanks a lot.

What factors make phosphorus a nutrient of concern in most ecosystems?

Too much phosphorus can cause increased growth of algae and large aquatic plants, which can result in decreased levels of dissolved oxygen– a process called eutrophication. High levels of phosphorus can also lead to algae blooms that produce algal toxins which can be harmful to human and animal health.

Which of the following processes cycles matter through different parts of an ecosystem?

The carbon cycle is the biogeochemical cycle in which carbon moves through the biotic and abiotic components of ecosystems. The carbon cycle is represented by the diagram in the figure below. In the carbon cycle, carbon moves from one carbon store to another. Carbon cycles quickly between organisms and the atmosphere.

Which statement best describes what ultimately happens to the chemical energy that is not converted to new biomass in the process of energy transfer B?

Which statement best describes what ultimately happens to the chemical energy that is not converted to new biomass in the process of energy transfer between trophic levels in an ecosystem? It is undigested and winds up in the feces and is not passed on to higher trophic levels.

Which of the following best describes the importance of biogeochemical cycles?

Which of the following best describes the importance of biogeochemical cycles? They show how certain elements and compounds move through the environment and are continually used and recycled.

How does the biogeochemical cycle work?

The biogeochemical cycle involves external transfers of elements among different components of a forest system. Uptake of nutrients from the soil and return of these nutrients in leaf fall, branch shedding, root growth and death, or through tree mortality is a major component of the biogeochemical nutrient cycle.

What problem can phosphorus lead to in nearby habitats when it is applied to agricultural fields?

Even small amounts of phosphorus runoff from farms and sewage are enough to fuel algal blooms that fill waterways with festering green scum. Sometimes, like in Lake Erie, they produce toxins that can foul drinking water and use up dissolved oxygen, killing fish and other aquatic life.
