Question

a bog is considered a carbon sink because:

it stores carbon in peat

it releases carbon

it has no plants

it is dry

Explanation:

A carbon sink is a reservoir that stores more carbon than it releases. Bogs accumulate partially decomposed plant material (peat) which stores carbon. Releasing carbon would mean it's a source, not a sink. Bogs have plants (like mosses), and they are wet, not dry. So the correct reason is it stores carbon in peat.

Answer:

A. It stores carbon in peat
