Ecosystem I
One factor that is not necessary for an ecosystem to be self-sustaining is the presence of humans or human intervention. While some ecosystems thrive with minimal human impact, others can be significantly altered or degraded by human activities. Therefore, an ecosystem can maintain its balance and resilience through natural processes like nutrient cycling and energy flow, independent of human presence.
Burning of fossil fuels, such as coal, is the human activity that has had the greatest impact on increasing mercury levels in the environment. When coal is burned, mercury is released into the atmosphere and can then be deposited into bodies of water where it accumulates in fish.
