Question

In an ecosystem there was loss of biodiversity due to some project in that area.

How will biodiversity be affected?

Answer 1

• Loss of species richness and abundance (fewer species and smaller populations). For example, removing key groups (e.g., all producers) reduces primary productivity and removes food/energy for higher trophic levels.
• Local extinctions and secondary extinctions (species that depend closely on lost species hosts, pollinators or specialist predators may also disappear).
