The student makes the claim that decreasing the size of forests will cause Earth to run out of oxygen. Does the student’s research support the concern?
es. Plants and cyanobacteria are mostly found in forests and are harmed by its decreasing size.
Yes. Farms and housing developments constructed in forests decrease nutrients available to freshwater and saltwater ecosystems
No. Oxygen is evenly produced by three kingdoms of organisms, if the destruction of forests decreases the population of one kingdom, then other two will increase
No. Most of Earth’s oxygen supply comes from saltwater organisms, and destruction of forests will have little effect on those organisms.

Which can be inferred from the information in the diagram?
Factories, plants, and animals all give off about the same amount of carbon dioxide to the atmosphere and absorb roughly equal amounts of oxygen.
Factories take in as much carbon dioxide from the atmosphere as they release through combustion of fossil fuels and have no impact on the carbon cycle.
Plants absorb more carbon dioxide from the atmosphere than they produce from cellular respiration and use less oxygen than they produce from photosynthesis.
Animals produce more carbon dioxide during cellular respiration than the oxygen they absorb from the atmosphere and disrupt the carbon cycle.
