what are biogeochemical cycles and what important role do they play in ecosystems?
283
These cycles are called biogeochemical cycles, because they include a variety of biological, geological, and chemical processes. Many elements cycle through ecosystems, organisms, air, water, and soil. Many of these are trace elements.

Why Conserve Plants? Plant diversity underpins the functioning of all ecosystems, which in turn provide the fundamental support systems upon which all life depends. Services provided by ecosystems include carbon sequestration, climate regulation, nutrient cycling and pollination.

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 .

The water cycle , also known as the hydrologic cycle, describes the continuous movement of water as it makes a circuit from the oceans to the atmosphere to the Earth and on again. Most of Earth's water is in the oceans. The sun, which drives the water cycle, heats water in the oceans.

In an ecosystem, numerous interactions between organisms result in a flow of energy and cycling of matter. Food chains, the nitrogen cycle, and the carbon cycle are examples of these interactions. A food chain is the sequence of steps through which the process of energy transfer occurs in an ecosystem.

The water cycle uses plants for uptake of water and transpiration from the surface, so that water can be sent to the atmosphere. Carbon cycle uses plants for uptake of CO2, by which it is removed from the atmosphere (and sent back to atmosphere when the plant is dead).

Answer: Biogeochemical cycles are a combination of biological, geological and chemical pathways. It is also known as an inorganic-organic pathway. Explanation: In this pathway, chemical elements move through living biological spheres or non-living/ abiotic spheres like atmosphere, hydrosphere or lithosphere in a cycle.

The important thing about ecosystems is that the organisms within them exchange energy and nutrients among themselves and with the environment. Energy and matter transfer from one organism to another organism through consumption.

Water cycle, also called hydrologic cycle, cycle that involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.

Energy must be continually added to the biosphere in the form of sunlight. ... In other words, the energy flow is one way. Matter, on the other hand, cycles through the living and non-living parts of the biosphere in what are termed biogeochemical cycles.

The nitrogen cycle. ... Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.

An ecosystem is a community of living organisms interacting with one another and their non-living environment within a particular area. ... The biosphere is that part of the earth inhabited by living organisms, including land, ocean and the atmosphere in which life can exist.

The carbon cycle. ... Carbon is a major component in carbohydrates, fats and proteins. The carbon cycle involves the exchange of carbon between living organisms (biotic) and their atmosphere (abiotic). In the carbon cycle, carbon is constantly removed from, and returned to, the environment.

An ecosystem is composed of biotic communities that are structured by biological interactions and abiotic environmental factors. Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow.

It is the interaction of the abiotic and biotic factors that describe a biome and ecosystem. In aquatic biomes, abiotic factors such as salt, sunlight and temperature play significant roles. For example, a hot dry biome is going to be completely different from a moderate wet biome.

There seems to be an ecological balance between all animals in nature. Some animals help to bring out the nutrients from the cycle while others help in decomposition, carbon, and nitrogen cycle. All animals, insects, and even micro organisms play a role in the ecosystem.
