For humans, population density is the number of people per unit of area, usually quoted per square kilometer or square mile (which may include or exclude, for example, areas of water or glaciers). Commonly this may be calculated for a county, city, country, another territory or the entire world.
Answer:
c.The atmosphere, a plant, a herbivore, a decomposer, then back to the atmosphere.
Explanation:
The carbon cycle is the biogeochemical cycle through which carbon is exchanged between the biosphere, pedosphere, geosphere, hydrosphere and Earth's atmosphere. Together with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that is key to making the Earth capable of sustaining life; describes the movement of carbon when it is recycled and reused by the biosphere, including carbon sinks.
A single carbon atom would more likely go from the atmosphere through being absorbed by a plant and, later, it would enter into the organism of a herbivore that eats the plant. After the herbivore dies, the carbon atom would enter into the organism of a decomposer that would expel it back again into the atmosphere.
A lunar eclipse happens on the moon, when the moon sails through the Earth's wide, fat shadow. Then, for a while, no sunlight can reach the moon, because the Earth is in the way. Anybody on the night side of Earth who looks up toward the moon sees it turn dark, until it sails out of the Earth's shadow after an hour or two.
A solar eclipse happens on the Earth, when the narrow end of the moon's skinny shadow falls somewhere on the surface of the Earth. Then, people who are inside that small spot and look up toward the sun can't see it, because the moon is in the way. The moon is moving so fast, and its shadow is so small, that this can only last for a few minutes at any one place.
