Question

1. why is biodiversity important in maintaining ecological balance?

a. it decreases the need for natural resources

b. it ensures a variety of species interactions that stabilize ecosystems

c. it limits the spread of native species

d. it reduces the number of predators in an ecosystem

Explanation:

• Option a: Biodiversity doesn't decrease the need for natural resources; organisms still rely on resources, so a is incorrect.
• Option b: Biodiversity means more species, leading to various interactions (like food webs, symbiosis) that make ecosystems stable. This matches the role of biodiversity in ecological balance.
• Option c: Biodiversity promotes the spread and survival of native species (and others) through diverse niches, so c is wrong.
• Option d: Biodiversity includes predators, and it doesn't aim to reduce them; predators are part of stable ecosystems, so d is incorrect.

Answer:

b. It ensures a variety of species interactions that stabilize ecosystems
