A city is planned to replace a pond, grassland, and trees with a park featuring playground equipment, shrubs, and paved paths. Which of the following consequences best reflects the impact on the local ecosystem?
Loss of aquatic habitat leading to reduced biodiversity in the area
A pond, natural grassland and trees together support many species — aquatic plants, fish, frogs, insects, birds and soil organisms.
Replacing them with a park of shrubs, paved paths and play equipment removes the pond completely, so the aquatic habitat and the organisms depending on it are lost.
With fewer habitat types and a few planted shrub species, the number of species the area can support falls — biodiversity is reduced.
Not all animals disappear, since birds, insects and some small animals still use parks; planted ornamental shrubs do not raise plant diversity enough to make up for the loss; and this human alteration disturbs rather than improves the ecological balance.
Hence, the answer is Loss of aquatic habitat leading to reduced biodiversity in the area.
