Rhizobium
Coal is formed due to the process of dead plant matter being buried and subjected to high pressure and heat over millions of years. This process, known as carbonization, converts the plant material into coal.
Decomposers are organisms that break down dead organic matter into simpler substances, like bacteria and fungi. Detritivores are organisms that consume those decomposed materials, such as earthworms and millipedes. Both play important roles in recycling nutrients in ecosystems.
Saprophytism is a type of nutrition in which an organism feeds on decaying organic matter. Fungi like mushrooms and bacteria are examples of organisms that exhibit saprophytism, playing a vital role in the decomposition of dead plant and animal material.
Coal is formed from dead plant matter, including trees, that was buried under layers of sediment millions of years ago. Over time, the plant material underwent heat and pressure, transforming it into coal through a process called coalification. This process converts the organic material into different forms of coal, such as lignite, bituminous coal, and anthracite, based on the depth of burial and heat applied.
Decomposers :)
Nitrogen fixation occurs in1 free living bacteria and archaea e.g. Azotobacter, Klebsiella, Clostridium, and Methanococcus,2 bacteria living in symbiotic association with plants such as legumes e.g. Rhizobium3 cyanobacteria e.g. Nostoc, Anabaena, and Trichodesmia.
Bacteria that feed on dead organisms are called decomposers. I will explain how it works with plants. When plants are eaten by an animal or have died there are called ammonium compounds. Then ammonium compounds are decomposed by bacteria called decomposers and turned into nitrites. Then they get nitrified by bacteria called nitriying bacteria and turned into nitrates. Then the nitrates are absorbed by the roots of plants and the cycle starts again. There is a cycle that includes this that might help. Its called the nitrogen cycle.
Nitrates
It is used for three main reasons:1 - To keep the tank physically clean: for viewing (clearer water, removes fish poo, removes excess food)2 - Biological filtration - this is key to successful fish keeping. All waste - fish poo, dead fish and decaying food release toxins (ammonia and nitrites) this is lethal to fish, the biological filter turns the ammonia into nitrites (also poisonous to fish). Finally the biological filter turns the nitrites into nitrates (which isn't poisonous to fish in small amounts) you keep the nitrates in check by partial water changes. For more info Read up on the Nitrogen Cycle.3 - Water movement and aeration - a fish needs oxygen to survive.
okay heres the nitrogen cycle nitrogen from atmosphere it taken in by 1)lightning( its energy causes nitrogen to react with oxygen n rain to the soil) 2)nitrogen- fixing bacteria in nodules ( plant roots which take it directly form the atmosphere ) NITROGEN FROM SOIL to organisms 1)nitrogen fixing bacteria in soil - breakdown of dead plants n animals releases nitrogen to the soil 2)fertilizers - which contain nitrogen compounds eg NPK OR natural fertilizers i,e dead plants n animals release nitrogen , animal urine and faeces release nitrogen as well to the soil 3)nitrogen fixing bacteria in nodules get nitrogen from its compounds in the soil 4)nitrifying bacteria - converts compounds of ammonia into nitrates .. for the plant nodules NITROGEN TO ATMOSPHERE 1) denitrifying bacteria in soil - changes nitrates to nitrogen gas and its released back to the atmosphere
If plants and animals lived forever, the nitrates in Earth's soil would continue to cycle through the ecosystem indefinitely. Nitrates are essential for plant growth and are constantly recycled by decomposers breaking down dead matter. Without the natural turnover of plants and animals, nitrates may become more abundant over time, potentially leading to nutrient imbalances in the soil.
Fungi convert dead and decaying matter into simpler compounds through a process called decomposition. This helps in nutrient cycling and enriching the soil with essential elements like carbon, nitrogen, and phosphorus, making them available for other organisms.
No, it does not feed off of dead plants and animals directly (as what certain types of fungus would). As with most plants they absorb the nutrients which are available in the soil after the decomposition process has taken place (fungi, bacteria etc). Clover (as with most legumes) is often used as a "green manure" as it is able to "fix" or convert nitrites into nitrates, which other plants can absorb.
When dead organisms decay, decomposer organisms break down their tissues and release nitrogen in the form of ammonium. This ammonium is further converted into nitrates by nitrifying bacteria in the soil. These nitrates can then be taken up by plants as nutrients, completing the nitrogen cycle.
Possible sources of nitrates in soil include fertilizers (both synthetic and organic), animal manure, sewage sludge, agricultural runoff, and atmospheric deposition. Nitrate can also be naturally present in soil due to nitrogen-fixing bacteria, decomposition of organic matter, and weathering of rocks.
1. Bacteria that nitrifies ammonium compounds in the soil (called "nitrifying bacteria"). Example: Nitrosomonas. 2. Bacteria that nitrifies nitrites (NO2-) in the soil (also called "nitrifying bacteria"). Example: Nitrobacter. 3. Bacteria that denitrifies nitrates (NO3-) in the soil (called "denitrifying bacteria"). Example: Pseudomonas denitrificans. 4. Bacteria that "fixes" nitrogen (called "nitrogen-fixing bacteria"). Examples: Rhizobium (which is symbiotic) and Azotobacter (which is free-living). 5. You also have bacteria that putrefies nitrogenous waste (like urea) and the protein in dead organisms. This type of bacteria is called putrefying bacteria.
the dead organic matter is overtaken by new plants.
