The statement that would best keep the world's oxygen supply from decreasing:
a.Planting trees in forests that have been harmed
Trees decrease the urban heat island effect via evaporation cooling and lessening the amount of sunlight that reaches parking lots and buildings.
<span>Pteridophytes (ferns) have true roots and vascular tissue that allows water to move farther
through the plant so that they don't depend on absorption of water held
on the plant as a mass of moss plants would.
Hope this helps!

The snowshoe rabbit will no longer be able to camouflage itself, thus resulting in a decline in its population due to death by predation.
What are abiotic factors?
Abiotic factors are nonliving components of an ecosystem, such as temperature, light, wind, and moisture. They are the physical and chemical elements of an environment that influence the structure and function of ecosystems. Abiotic factors shape the biotic, or living, components of an ecosystem, which include plants, animals, and microorganisms. Abiotic factors determine what species of life can live in a particular ecosystem. For example, a cold, wet climate will support different species of plants and animals than a hot, dry climate. Abiotic factors also determine the carrying capacity, or the number of organisms that can be supported, of a given environment. Abiotic factors are essential to the functioning of all ecosystems and are constantly changing due to natural processes and human activities.
