Answer:
Oxygen
Explanation:
Because it’s oxygen I don’t know ♀️
(C.) The layers of the Earth are uniform in thickness
This is untrue. The mantle is far large than the crust and there are other large size differences.
D. Polar regions receive less solar energy and heat per unit area than tropical regions
Less direct sunlight means that there is less concentration of direct solar rays. This would influence temperature and would ultimately create weather, and since this pattern continues of switching direct ray latitudes, this would create climate zones all over the Earth, and similar ones with similar latitude and terrain.
Sunlight doesn't reach quite as well in deeper parts of the ocean. Therefore, the autotrophs cannot use photosynthesis to make food.
