What are two roles prokaryotes play in the cycling of elements in an ecosystem
Illusion [34]
Prokaryotes have a significant role in decomposition of organic matter, bringing back key nutrients into the trophic network. By decomposing dead plant or animal parts, they enable the circulation of elements like phosphorus and sodium.
On the other hand, specialized bacteria have a role in transforming nitrogen compounds in the soil, converting them into chemical forms that are suitable for other organisms to use.

Savatey [412]

<u>Answer</u>:

"It increases the mutation rate"  is an advantage of  sexual reproduction

<u>Explanation</u>:

The basic thing of evolution is fundamental, as it helps in generation of genetic variation on which the selection can act. Sexual reproduction leads to genetic diversity, and this genetic diversity leads to increase the mutation rate. Genetic diversity occurs because of two various cells which are combining together and biological assortment which happens at the time of cell division. Neutral genetic diversity in the population leads to high mutation rate.
