What is the main reservoir of nitrogen in the biosphere?
The main reservoir of nitrogen in the biosphere is the atmosphere. Nitrogen gas (N2) makes up about 78% of Earth's atmosphere. Nitrogen is cycled through the biosphere by processes like nitrogen fixation, nitrification, and denitrification.
By which process is oxygen cycled through the biosphere?
photosynthesis
When nitrogen is returned to the soil when dead plants decompose the interaction is between which earth spheres?
When nitrogen is returned to the soil through the decomposition of dead plants, the interaction is primarily between the biosphere (dead plants) and the geosphere (soil). The nitrogen is cycled through these two spheres as part of nutrient recycling in ecosystems.
Is nitrogen cycled through the earth's atmosphere?
Yes, nitrogen is cycled through the Earth's atmosphere through a process known as the nitrogen cycle. This cycle involves various processes such as nitrogen fixation by bacteria, denitrification, and nitrification, leading to the conversion of nitrogen into different forms that can be used by living organisms.
Is nitrogen and carbon used up by the prosses of a biosphere?
In a biosphere, nitrogen and carbon are cycled through various processes such as photosynthesis, respiration, and decomposition. While these elements may be temporarily taken up by organisms, they are continuously recycled back into the ecosystem. Nitrogen is utilized by organisms for growth and energy, while carbon is a key component of organic molecules essential for life.
Describe why nitrogen must cycle through an ecosystem?
Nitrogen must be cycled through an ecosystem so that the nitrogen is available for organisms to make proteins.
What is the recycling of carbon nitrogen in nature?
In nature, the recycling of carbon and nitrogen occurs through various processes. Carbon is cycled through photosynthesis, respiration, and decomposition. Nitrogen is cycled through nitrogen fixation by bacteria, uptake by plants, consumption by animals, decomposition, and denitrification. These cycles ensure that carbon and nitrogen are continuously reused by organisms in the ecosystem.
What of these is not cycled through the earth atmosphere?
Water vapor is not cycled through the atmosphere of the earth. While water does evaporate into the atmosphere and precipitate back to the earth's surface, the water molecules themselves are not cycled through the atmosphere in the same way that gases such as nitrogen and oxygen are.
How nitrogen cycles through the biosphere?
it goes thorugh a pcocess called nitrateisattion
What kind of relationships do plant have with nitrogen fixing bacteria?
It allows nitrogen atoms to continually cycle through the biosphere.
What is the process necessary to convert atmospheric nitrogen to terrestrial forms of nitrogen that can be cycled by organisms?
Atmospheric nitrogen is converted to terrestrial forms by nitrogen-fixing bacteria. These bacteria convert atmospheric nitrogen into ammonium through a process called nitrogen fixation. Plants then take up this ammonium and use it to produce proteins and other nitrogen-containing molecules, which are then consumed by animals. This allows the nitrogen to be cycled through the ecosystem.
How do nitrogen fixing bacteria help cycle nitrogen through ecosystem?
Nitrogen-fixing bacteria help cycle nitrogen through the ecosystems in a variety of ways. With plants, the nitrogen-fixing bacteria help ensure that nitrogen is cycled back into the soil.
