Question

here is a very simple model of part of the carbon cycle. place the applicable labels where they should go, then click \submit response.\ respiration photosynthesis fossil fuel formation decomposition combustion score: 0% submit response

Explanation:

To solve this, we analyze the carbon cycle steps. The left box (connected to the arrow towards CO₂) should be a process that releases CO₂ (like Respiration, Decomposition, Combustion). The right box (connected to the arrow from CO₂ to the plant) should be Photosynthesis (as plants take in CO₂ for photosynthesis). Let's assume the left process is Respiration (organisms release CO₂) and the right is Photosynthesis (plants use CO₂).

Answer:

Left box: Respiration
Right box: Photosynthesis

(Note: Other valid left - side processes could be Decomposition or Combustion, but Photosynthesis is the key process for the plant - CO₂ intake side.)
