Question

students are creating a model to show how plants and animals are involved in carbon cycling. what is the role of each component in the carbon cycle? move the correct answer to the box to show how carbon moves between systems.
(image of a model with boxes labeled air, plant, plant or animal and descriptions: oxygen source, breaks down glucose with water, carbon dioxide source, produces oxygen, stores carbon in glucose, produces carbon dioxide)

Explanation:

1. Air: Acts as the main reservoir of carbon dioxide, which plants take in, and also receives carbon dioxide from organisms.
2. Plant: Uses carbon dioxide from air to perform photosynthesis, making glucose (storing carbon) and releasing oxygen.
3. Plant or animal: Performs cellular respiration, breaking down glucose with oxygen to release carbon dioxide back to the air.

Answer:

• Air box: carbon dioxide source
• Plant box: stores carbon in glucose, produces oxygen
• Plant or animal box: breaks down glucose with water, produces carbon dioxide, oxygen source
