Q.2	An environmental organisation has embarked on a project aimed at restoring a degraded river ecosystem. The project involves reintroducing native fish species that have declined due to habitat degradation and water quality issues. Additionally, efforts are being made to improve overall water quality by implementing measures to reduce pollution and restore natural habitat. What could be an anticipated outcome of this restoration effort in the degraded river ecosystem?
	a) Increased biodiversity with the recovery of native fish populations and the return of other aquatic species.		b) Further degradation due to competition among reintroduced fish species and disruption of the existing ecosystem balance.
