what are the biogeochemical cycles of nutrients?

In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth.

Answer and Explanation: The phosphorus cycle differs from the nitrogen cycle and the carbon cycle because phosphorus doesn't have a gas phase as a part of the cycle.

The water cycle is the endless process that connects all of that water. It joins the Earth's oceans, land, and atmosphere. The Earth's water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans.

Sources of Essential Nutrients for Microorganisms Microorganisms (or microbes) vary significantly in terms of the source, chemical form, and amount of essential elements they need. Some examples of these essential nutrients are carbon, oxygen, hydrogen, phosphorus, and sulfur.

What is the Nitrogen Cycle? Overview: The nitrogen cycle involves three major steps: nitrogen fixation, nitrification, and denitrification. It is a cycle within the biosphere which involves the atmosphere, hydrosphere, and lithosphere. Nitrogen is found in several locations, or reservoirs.

The phosphorus cycle. Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. ... Once in the plant or animal, the phosphate is incorporated into organic molecules such as DNA.

Which of the following statements is true about chemical nutrients in an ecosystem: ... they cycle within the ecosystem and are constantly reused; they can be converted to energy; they depend on sunlight as their source; they cannot be obtained from decomposition?

Nutrient recycling and energy flow. Which substance is NOT recycled but rather lost from ecosystems? energy.

Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.

Along with energy, water and several other chemical elements cycle throughecosystems and influence the rates at which organisms grow and reproduce. The most important biogeochemical cycles affecting ecosystem health are the water, carbon, nitrogen, and phosphorus cycles.

The global carbon cycle, one of the major biogeochemical cycles, can be divided into geological and biological components. The geological carbon cycle operates on a timescale of millions of years, whereas the biological carbon cycle operates on a timescale of days to thousands of years.

Fish play an important role in nutrient cycles because they store a large proportion of ecosystem nutrients in their tissues, transport nutrients farther than other aquatic animals and excrete nutrients in dissolved forms that are readily available to primary producers.

The phosphorous and the carbon cycles are both biogeochemical cycles on earth that are crucial to how our world functions. The two cycles include two different elements. The other large difference between these two cycles is that carbon cycles through the atmosphere whereas phosphorus does not .

Which one of the following is not a gaseous biogeochemical cycle in ecosystem? B. Phosphorus cycle is a sedimentary biogeochemical cycle. It describes the lithosphere, hydrosphere and biosphere and the main reservoir pool is lithosphere.

What is a fundamental difference between the water cycle and other nutrient cycles? The difference is that the nitrogen cycle, and the carbon cycle include chemical changes, which is when it changes and does something else, but the water cycle doesn't.
