The statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.
<h3>What is eutrophication?</h3>
Eutrophication is the ecosystem's response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.
Eutrophication is one major effect of the anthropogenic activities that release inorganic nutrients such as phosphate, nitrate etc into aquatic ecosystems.
However, eutrophication has its negative impacts on biogeochemical cycle as it alters the cycling of these nutrients.
Therefore, the statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.

Answer:
Option-4
Explanation:
In the given question, S. alterniflora grows in the seaward marsh whereas S. patensis grows in the high marsh. When S. alterniflora is removed, the S. patensis grows to a smaller portion whereas if S. patensis is removed, the S. alterniflora covers all the land.
This shows that although both are different species but they share a niche and the marsh land is the fundamental niche of the S. alterniflora as it can grow in all parts and therefore its distribution is limited by only a realised niche.
Thus, Option-4 is correct.
