Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills.

There are many reasons on how human activities can lead to he imbalance of biochemical cycling. In reality anything that the can cause damage to our natural environment, change the imbalance, or that our natural environment is not familiar with can damage the balance. Cultural eutrophication and fish kills are mainly caused due to the lack of oxygen also known as anoxia. Although eutrophication is naturally occurring, it is a slow and inevitable process. Yet human when humans speed up that process by adding pollutants into our ecosystem, this will cause the death and premature aging of bodies of water due to the contamination with sewage, chemicals, and fertilizers. This will then cause the slow death of that body of water due to anoxia killing all living things within it.

The comparison between opportunistic versus equilibrium populations are as follows: opportunistic species use the “r-strategy” and the equilibrium uses the “k-strategy”. In the Opportunistic species, the “r” defines the species instrinsic rate of increase. This species produces millions of sperms and eggs mainly because only a minimal amount will actually become offspring. Whereas, in the equilibrium species, the “k” defines the carrying capacity of the environment. This species, in contrast, produces a small amount of sperm and eggs, thereby, producing less offspring. Both species also have different mannerisms in which they care for their offspring. Where opportunistic spawn and fertilize their eggs in water and equilibrium nest their eggs and brood over them. Examples of opportunistic versus equilibrium are insects or coral versus birds or mammals Biodiversity provides both indirect and direct values, which benefit humans and animal
