Carbon Sources: Carbon sources are nutrients which provide the carbon required for cellular biosynthesis. Some examples of carbon sources are people breathing, people sticking their tongue out, and a factory.
Release Agents: Release agents are chemicals used to get slip effects. Some examples of release agents are people jumping rope, people making peace signs, and volcanic activity.
How Carbon Sources can be Harmful:
When forest fires happen, this is bad for the environment. This is because smoke is bad for the plants, animals, and humans. Some creatures that live underwater can get affected by smoke too. It can choke these living organisms to death, or just sicken them.
Also, when a factory is working, the smoke coming out of the chimney is very bad for the environment. It has the same effect on living organisms as a forest fire does, but the smoke is not natural like smoke coming out of fire that affects forests.
