question 7
all living organisms contain carbon. as organisms grow, they require large quantities of carbon to carry out life processes and make new cells. what is the source(s) of the most often used of earth’s readily available short term carbon stores?
a new carbon atoms are constantly being created by the process of photosynthesis.
b carbon atoms are constantly transferred from the sun to earth along with sunlight.
c carbon is constantly transported from the mantle to the crust by volcanic eruptions.
d carbon is constantly recycled from dead and living organisms back into the soil, water and atmosphere.

Explanation:

For Question 6: Plants perform photosynthesis, a process that actively removes carbon dioxide (a major atmospheric carbon form) from the air to produce organic molecules, far more than the other listed organisms which are mostly heterotrophs that release or cycle carbon rather than removing large amounts from the atmosphere.
For Question 7: Short-term carbon stores rely on the constant recycling of existing carbon from dead and living organisms back into accessible reservoirs like soil, water, and atmosphere. Photosynthesis does not create new carbon atoms, carbon does not come from the Sun, and volcanic eruptions move carbon from long-term deep Earth stores, not short-term accessible ones.

Answer:

Question 6: d. Plants
Question 7: d. Carbon is constantly recycled from dead and living organisms back into the soil, water and atmosphere.
