Question

7 why is biodiversity important to ecosystems? a biodiversity allows ecosystems to adapt to a changing climates. b biodiversity establishes the separate ecosystems within a biome. c biodiversity provides each organism with one specific role to ensure there is no competition. d biodiversity has created antibiotic resistant bacteria and super pests which has prevented extinction of some spec

Explanation:

Biodiversity refers to the variety of life in an ecosystem. A diverse ecosystem with many different species is more resilient. When the climate changes, having a wide range of species means that there is a higher chance that some species will be able to adapt and survive. This helps the ecosystem as a whole to continue functioning.

• Option B: Biodiversity does not establish separate ecosystems within a biome. Biomes are large - scale ecological areas, and ecosystems within a biome are more about physical and environmental factors rather than just biodiversity.
• Option C: In an ecosystem with biodiversity, there is competition. Organisms compete for resources like food, water, and space. The idea that biodiversity ensures no competition is incorrect.
• Option D: Antibiotic - resistant bacteria and super - pests are more of a negative consequence of human activities (such as over - use of antibiotics and pesticides) rather than a positive aspect of biodiversity for the ecosystem's well - being in a general sense.

Answer:

A. Biodiversity allows ecosystems to adapt to a changing climates.
