Question

drag the labels onto the diagram to identify how chemicals cycle in an ecosystem. ecosystem gas we exhale water photosynthesis (in chloroplasts) cellular respiration (in mitochondria) for cellular work food that plants produce gas produced by photosynthesis sunlight energy o₂ co₂ h₂o glucose atp

Explanation:

In photosynthesis, plants take in carbon - dioxide ($CO_2$) and water ($H_2O$), use sunlight energy to produce glucose and oxygen ($O_2$). In cellular respiration, organisms take in oxygen, break down food to produce ATP for cellular work, and release carbon - dioxide and water. The gas we exhale is carbon - dioxide. The gas produced by photosynthesis is oxygen.

Answer:

Gas we exhale: $CO_2$
Water: $H_2O$
Food that plants produce: glucose
Gas produced by photosynthesis: $O_2$
