Photosynthesis

Multiple Choice

Why is carbon considered a central building block for all living things on Earth?

• Because it is the most abundant element in the atmosphere

• Because it is present in both living and non-living matter and cycles through different reservoirs

• Because it is only found in living organisms

• Because it never changes its location
