Dear public, our ecosystem is being ruined and we need to stop it, i think you should do something about the littering and loitering in our community and in the U.S. it would help a lot of people if you made a law against it or if we went out and all did community service and helped pick up. if you don't like these ideas we could protest, but all me and my fellow people ask is that you help our <span><span>ecosystem for better lives for everyone! yours truly, citizen</span></span>
Answer:
A.The weak force acts within protons and neutrons, and the electromagnetic force has an infinite range.
Explanation:
Weak force explanis the interaction among subatomic particles (e.g. protons and neutrons) and is directly involved in the radioactive decay of the atoms. This is the reason that it has been well studied to understand nuclear fission reactions. Its range is very limited and does not exceeds beyond subatomic particles.
On the other hand, electromagnetic force is a very strong force that holds atoms together. It has infinite range. Once can assume the strength of this force from the basic understanding that, within an atom, electrons and protons exist together despite of their opposite charges. Nevertheless, the integrity of atom is not disturbed.

The correct option is this: BREAKING CARBON BONDS RELEASE ENERGY THAT ORGANISMS USE FOR LIFE PROCESSES.
The food that are eaten by living organisms are composed of carbon element which bond in various ways with other elements. Chemical energy are stored inside this bonds and released for the organisms use when they are broken.
