EVERYDAY SCIENCE

Detailed explanation-1: -Animals obtain their carbon by eating plants; they release carbon in respiration. Micrororganisms (such as fungi and bacteria) return carbon to the environment when they decompose dead plants and animals.

Detailed explanation-2: -When animals eat food, they get carbon in the form of carbohydrates and proteins. In animals, oxygen combines with food in the cells to produce energy for daily activity and then gives off carbon.

Detailed explanation-3: -Animals get carbon by eating plants or by eating other animals. Different products produce differing amounts of greenhouse gases. Common greenhouse gases include carbon dioxide, carbon monoxide and methane.

Detailed explanation-4: -Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle.

Detailed explanation-5: -Animals obtain carbon through plants. Note: The process in which the plants take up carbon dioxide, prepare food which later is consumed by animals and when both die, their remains makes up the carbon in soil and eventually goes into the atmosphere, is termed as carbon cycle.
