Question

1. what does it mean to be a carbon sink?

Explanation:

In environmental science, carbon sinks play a crucial role in regulating the amount of CO₂ in the atmosphere, which affects climate change. They act as a "sink" by taking in more carbon than they release.

Answer:

A carbon sink is a natural or artificial reservoir that accumulates and stores some carbon - containing chemical compounds for an indefinite period. It removes carbon dioxide (CO₂) from the atmosphere through processes like photosynthesis in plants, absorption in the ocean, or geological sequestration.
