Which of the following in the lower atmosphere is of little use to man,plants and animals?
Answer Details
Argon in the lower atmosphere is of little use to man, plants, and animals. Argon is an inert gas and it makes up about 0.93% of the Earth's atmosphere. It is colorless, odorless, and non-reactive with other elements, so it has no significant role in supporting life or other natural processes. Carbon dioxide is used by plants during photosynthesis, oxygen is vital for respiration and nitrogen is essential for the growth and development of plants.
