Answer:
The correct answer is option d.
Explanation:
Chemical cycling illustrates the systems of concurrent circulation of elements between other states, compounds, and substances, and then return to their original state, which takes place in space, and on many objects in space comprising the Earth.
Chemical cycling of the nutrients (inorganic) is needed to maintain the conservation of nutrients on Earth. The chemical cycling of nutrients in a natural system requires a pool for the elements, the activities done by human beings, the biotic community and its food chains, and an exchange pool from which producers extract their nutrients. All the mentioned factors are associated with affecting a chemical cycling in exception to the input of geothermal energy.
Quaternary or fourth order consumers are those who occupy the fourth position in the trophic level or food chain, that is, they are species or organisms that feed on tertiary consumers
Must be a comet I believe
The movement of ions across the cell of a membrane of higher regions of concentration.
So it's going to be obviously oxygen XD ....so that's one
Next, it's going to be carbon dioxide, since it has to exit the cell, because it is a waste product ...so that's two
Finally, it's also going to be something you drink everyday.
*whispers* it's water XD because of osmosis
So recap:
1) Oxygen 2) Carbon Dioxide 3) Water
hope that helps!! :D
