As a scavenger bat star is important in the ecosystem helping clean dead animals,  and algae from the seafloor, the bat star keeps the seafloor healthy. 4. Phytoplankton are accounted for about half of photosynthesis on the planet, which makes them an important producer of oxygen, and serves as food source for smaller sea organisms, they consume carbon dioxide that would otherwise dissolve in the sea water making it more acidic. 5. Zooplankton are the animal like primary consumers of plankton community they also provide the base for the entire food web also if plankton disappeared it would increase the levels of carbon in our air.

ATP contains a large amount of energy because ______.
Lunna [17]

The right option is; D) It has high-energy phosphate bonds  

ATP contains a large amount of energy because it has high-energy phosphate bonds.

Adenosine triphosphate (ATP) is an organic molecule that performs important roles as an energy transport molecule, a phosphate donor, and a signaling molecule within cells. ATP is made up of adenosine (an adenine ring and a ribose sugar), and three phosphate groups. ATP is an unstable molecule which hydrolyzes when it react with water to form ADP (adenosine diphosphate) and inorganic phosphate. The large amount of energy of ATP comes from the two high-energy phosphate bonds.
