Hey there, thx for posting your question to Brainly, i've posted some information below and an explanation, hope it helps you<3
Carbon moves from the atmosphere to plants. In the atmosphere, <em>carbon is attached to oxygen in a gas called carbon dioxide (CO2)</em>. Through the process of <u>photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.</u>
<u>Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.</u>
<u>Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.</u>

Any infectious diseases can be prevented by vaccinations
<u>Explanation:</u>
- Vaccines defend against infectious diseases that cause severe illness and seldom death.
- It prevents disease in somebody who receives them and protects those who get into contact with unvaccinated individuals.
- Vaccines include the corresponding antigens or parts of it that cause illnesses, but the antigens in vaccines are either destroyed or incapacitated.
- When they are introduced into fatty tissue or muscle, vaccine antigens are not powerful enough to generate the symptoms and signs of the disease but are tough enough for the immune system to build antibodies against them.
