Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Biodiversity loss negatively impacts ecosystems' ability to sequester carbon. When diverse plant and animal species are lost, the ecosystem's capacity to absorb and store carbon dioxide is reduced, leading to an increase in atmospheric carbon levels.
