Carbon dioxide can be trapped by:
Use of carbonates by marine animals to make their shells
Breakdown of glucose by eukaryotes using oxygen
Burning of fuels
Respiration
Marine animals can use carbon dioxide to make their shell.
Consider the following statements regarding the ways in which carbon dioxide is “fixed” and choose the correct option.
1. Green plants convert carbon dioxide into glucose in the presence of sunlight.
2. Marine animals use carbonates dissolved in sea water to make their shells.
