Coral reefs form in warm, shallow waters.
Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.

The sporophyte generation produces spores that grow into a GAMETOPHYTE.
Molecules in food contains chemical energy that cells use to produce MORE CELLS. This energy is gotten from the chemical bond energy in food molecules, which in this way serve as fuel for cells. The particles in food additionally give the atoms that animals need to develop new living matter.
