Ammonium; nitrates; nitrites
Organic matter is produced by producers, such as plants, through the process of photosynthesis. Once organisms die, decomposers, like bacteria and fungi, break down the organic matter into simpler compounds, releasing nutrients back into the environment.
Free nitrogen produced by bacteria is eventually incorporated into plant and animal tissues through the process of nitrogen fixation. This cycle continues as nitrogen is passed through the food chain and returned to the soil through decomposition of organic matter. Some nitrogen is also released back into the atmosphere through denitrification by bacteria.
The chemical formula for methane is CH4. It is a simple hydrocarbon gas that is the main component of natural gas and is produced by the decomposition of organic matter.
Heterotrophic bacteria rely on organic compounds produced by other organisms as a food source, as they are unable to produce their own through photosynthesis or chemosynthesis. These bacteria obtain nutrients by consuming or decomposing organic matter from their environment.
The gas produced by the breakdown of organic matter in the absence of oxygen is called methane. This process, known as anaerobic decomposition, occurs in environments such as wetlands, landfills, and digestive systems of some animals. Methane is a potent greenhouse gas and is a significant component of natural gas.
water
Biomass energy is produced through burning organic matter.
Organic matter decays into simpler compounds such as carbon dioxide, water, and organic molecules. This decomposition process is carried out by microorganisms like bacteria, fungi, and other decomposers.
Energy from organic matter is typically referred to as bioenergy. It is produced from biomass sources such as wood, crop residues, and organic waste through processes like combustion, fermentation, and anaerobic digestion. Bioenergy is considered renewable because the organic matter used to produce it can be replenished through natural processes.
Organic matter is produced by producers, such as plants, through the process of photosynthesis. Once organisms die, decomposers, like bacteria and fungi, break down the organic matter into simpler compounds, releasing nutrients back into the environment.
The main gas produced by rotting organic matter is methane. Methane is a potent greenhouse gas that is released during the decomposition of organic material in anaerobic (oxygen-deprived) environments.
H2O and CO2
Biogas is produced through the anaerobic digestion of organic materials like animal manure, food waste, or agricultural residues by bacteria in an oxygen-free environment. During this process, the bacteria break down the organic matter, releasing methane gas that can be collected and used as a renewable energy source.
Because fossil fuels are produced from dead organic matter. Then the fossil fuels are burnt, and they release carbon.
Primary productivity measures the rate at which energy is captured and converted by photosynthetic organisms through the process of photosynthesis. It quantifies the amount of organic matter produced by autotrophs in an ecosystem, forming the basis of the food chain for all organisms in the ecosystem.
Organic matter is matter that is from living sources, such as animal manure, leaves, grass clippings etc. As the organic matter breaks down, worms, grubs and microorganisms incorporate it into the soil.
Biofuels are fuels used in powering machinery such as automobiles that are produced from organic matter, such as corn. They differ from fossil fuels which may have originally been organic matter but have changed chemically.
