Juanita is planning a scientific experiment to observe and record her community’s daily activities that release carbon dioxide into the atmosphere. She will use the data collected to construct a model. This will help make informed decisions on how best to reduce emissions and protect the environment. Which of the following activities would increase the amount of carbon dioxide in the atmosphere? Choose the three that apply.
A. plants conducting photosynthesis
B. eating a sandwich
C. a deer dies along the road
D. cutting down trees in a forest
E. driving a car to the store

C, D, E

Explanation:

A: When plants photosynthesize, they actually use carbon dioxide in the process. Therefore, that would decrease the amount of carbon dioxide, so this choice is wrong.

B. Eating a sandwich has no effect on carbon dioxide levels.

C. If an animal dies, they are broken down by decomposers. During this process, any carbon in the animal's body is released into the atmosphere as carbon dioxide. This would increase the amount of carbon dioxide.

D. As stated before, plants photosynthesize. If we cut down trees, there will be fewer plants to take in carbon dioxide during photosynthesis. This will increase carbon dioxide levels.

E. When a car converts fuel into energy to move the car, carbon dioxide is released. Driving a car will increase carbon dioxide in the atmosphere.

C, D and E are correct.
