The environment forces things to evolve so they can survive
If the farmer wants the pond to be more sustainable, he has to have a greater diversity of living organisms in the pond.
<h3>What is an ecosystem?</h3>
The term ecosystem means a self supporting unit in which there is an exchange of materials and energy. The ecosystem is expected to be self sustaining.
When the farmer adds young individuals from two species of algae-eating fish to the ponds and plants some reeds around the edge of the pond, if the farmer wants the pond to be more sustainable , he has to have a greater diversity of living organisms in the pond.

SN2 reaction proceeds with inversion of configuration at the reacting carbon atom. The product has a different configuration at this carbon atom from the product.
SN2 reaction is a short form for substitution nucleophilic bimolecular reaction. It is a synchronous reaction in which the leaving group departs at the same time as the nucleophile attacks in a single transition state.
Recall that SN2 reaction proceeds with inversion of configuration hence the product has a different configuration at the reacting carbon atom from the product. The inorganic product in this reaction is HI. The organic product is shown in the image attached to this answer.
