<h2>Answer:</h2>
Soil bacteria are mainly involved in four steps in nitrogen cycle.
- Nitrogen fixation
- Nitrification
- Ammonification
- Denitrification
<h3>Explanation:</h3>
- First of all atmospheric nitrogen is fixed by soil bacteria (N2 to NH3/ NH4+, NO3-)
- Nitrification: The conversion of ammonium to nitrate is performed primarily by soil-living bacteria and other nitrifying bacteria (NH3 to NO3-)
- When a plant or animal dies or an animal expels waste, the initial form of nitrogen is organic. Bacteria or fungi convert the organic nitrogen within the remains back into ammonium (NH+4), a process called ammonification.
- Denitrification is the reduction of nitrates back into nitrogen gas (N2), completing the nitrogen cycle. This process is performed by bacterial species such as Pseudomonas and Clostridium in anaerobic conditions.
Understandable, have a great day
If a invasive species were to intervene in the food web then it would break the web because it if were to kill the species it attacked then the web would be broken and a native species might also do the same.
The correct answer is : Light energy is captured by plants; light energy is converted to chemical energy.
In the process of photosynthesis, special pigment molecule called chlorophyll can capture the energy of the light, more specifically the photon. When a particle of light (a photon) with a specific energy reaches this pigment in the leaves of plants, the energy is transferred from the particle to the molecule, and the molecule becomes excited. This is the phase where the energy of the light is captured and transformed into chemical energy that can later be used to make sugars.
All of the later chemical processes that transfer the energy from the excited chlorophyll to the sugar molecules are not dependent on the light and can happen during the night as well.
