Short Answer Questions Describe what occurs in the carbon cycle? (3)

Answer 1 The carbon cycle happens in a number of steps: 1. plants take carbon dioxide and release oxygen. The carbon dioxide is then converted into carbon compounds. 2. Then animals give out carbon dioxide. Carbon stored in plants that are not eaten by animals eventually decomposes after the plants die and goes back.

Answer 2 The amount of carbon on the earth and in the earth’s atmosphere is fixed, but that fixed amount of carbon is dynamic, always changing into different carbon compounds and moving between living and non- livings. Carbon is released to the atmosphere from what are called “carbon sources” and stored in plants, animals, rocks, and water are called “carbon sinks”. This process occurs in a number of steps:

Answer 2 1. Through photosynthesis, plants take carbon dioxide out of the atmosphere and release oxygen. The carbon dioxide is converted into carbon compounds that make up the body of the plant, which are stored in both the above ground parts of the plants (shoots and leaves) and belowground parts of the plants (roots).

Answer 2 2. Then animals eat plants, breath in oxygen and exhale carbon dioxide. The carbon dioxide created by animals is then available for plants to use in photosynthesis. Carbon stored in plants that are not eaten by animals eventually decomposes after the plants die, and is either released into the atmosphere or stored in the soil.
