Explanation:
In ecology, allogenic succession is mediated by the abiotic components of the ecosystem, while the autogenic succession refers to the succession, which is mediated by the biotic components of an ecosystem.
A volcanic eruption wiping out an entire island is an example of allogenic succession.
A soybean crop helping in nitrogen fixation, leading to the development of other species is an illustration of autogenic succession.
A tsunami devastating all the living organism in a habitat is an example of allogenic succession.
Oak trees preventing the growth of smaller sun-seeking shrubs is an example of autogenic succession.
<span>One test might be the acid content of the water. Water that does not have a neutral pH might be less conducive to life. Another water quality test might be oxygen levels in the water. Inadequate oxygen levels may also reduce the amount of aquatic life. The presence of pollutants might be a third test. Chemicals that poison the water would negatively impact the number and variety of organisms present.</span>
The answer is Redshift in electromagnetic spectrum. hope this helps, have an amazing day :)
