earth oxygen cycle
the oxygen cycle begins with the process of photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere, which humans and animals breathe in oxygen and breathe out carbon dioxide
what is atmosphere biosphere
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
what is photosynthesis
Nitrogen fixation is the process by which nitrogen is taken from its molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other biochemical processes. Fixation can occur through atmospheric (lightning), industrial, or biological processes.
what is nitrogen fixation
Oceans cover more than 70 percent of the Earth's surface, making them the biggest part of the hydrosphere. The hydrosphere is simply the total of all the water in Earth's atmosphere.
what is atmosphere hydrosphere
Plants constantly exchange carbon with the atmosphere. Plants absorb carbon dioxide during photosynthesis and much of this carbon dioxide is then stored in roots, permafrost, grasslands, and forests. Plants and the soil then release carbon dioxide when they decay.
what is exchange
This is the conversion of organic forms of nitrogen (e.g. in dead organisms and their excretions) into inorganic nitrogen. A wide range of soil fungi and bacteria, called the decomposers, carry out the ammonification process.
what is ammonification
The four spheres are the geosphere (all the rock on Earth), hydrosphere (all the water on Earth), atmosphere (all the gases surrounding Earth), and biosphere (all the living things on Earth). To better understand how the 4 spheres of the Earth work
what is biosphere hydrosphere
When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals. Some of this sediment might form fossil fuels, such as coal, oil, or natural gas, which release carbon back into the atmosphere when the fuel is burned.
what is sedimentation
is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Ammonia is present in drinking water through either naturally-occurring processes or through ammonia addition during secondary disinfection to form chloramines.
what is Nitrification
The blank, also called the blank, is a complex chemical procedure that takes nitrogen from the air and under high pressures and temperatures combines it with hydrogen to produce ammonia. This ammonia is the base of the synthetic nitrogen fertilizers increasingly used around the world today.
