Question

question 25 (multiple choice worth 4 points) (03.04r mc) how do coral reefs help with climate stability? they need small amounts of carbon dioxide for energy. they use less carbon than mangroves and seagrasses. they are habitats for species that build exoskeletons from carbon. they release extra carbon dioxide into the atmosphere.

Explanation:

Coral reefs host organisms like corals which use carbon - based compounds to form their exoskeletons, sequestering carbon and thus helping with climate stability. Other options are either incorrect (corals don't release extra CO₂ for climate stability, and the comparison with mangroves/seagrasses isn't a main climate - stability factor here) or not the key way they contribute to climate stability (needing small amounts of CO₂ for energy isn't the main mechanism).

Answer:

They are habitats for species that build exoskeletons from carbon.
