Indicate whether the following would increase or decrease the amount of co2 in the atmosphere: a) increasing the number of plants – b) burning fossil fuels – c) increasing the number of animals – d) deforestation –

a). Decrease.

Plants can absorb carbon dioxide from the air in the process of photosynthesis, where they make food using carbon dioxide and sunlight. Therefore, the carbon dioxide in air would decrease.

b). Increase.

Burning of fossil fuels, or combustion, releases not only carbon dioxide, but also other greenhouse gases like nitrous oxides. That's why people nowadays recommend renewable energy like solar energy instead of nonrenewable energy produced by burning of fossil fuels. So, the answer is increase.

c). Increase

During respiration, animals release carbon dioxide and breathe in oxygen. Carbon dioxide are waste to the body. Therefore, the more animals there are, the more carbon dioxide we exhale each and every day.

d). Increase.

Deforestation is the removal of large scale of forest and trees. As we already said in part a, plants (or trees) absorb carbon dioxide for photosynthesis. Therefore, if the trees are removed, there would be less carbon dioxide being absorbed and removed from the atmosphere.

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.

biology is the study of life. it is the study of living organism.
