An organism is d. a group of organ systems working together.
An atom goes into a molecule which goes into a cell which goes into a tissue which goes into an organ which goes into an organ system which goes into an organism.
Organs working together with other organs create a system of organs or an organ system. Something like this helps keep a human body, for example, functioning since everything relies on each other.

Answer:
Reduce, Recycle, and Reuse.
Explanation:
Reduce your use of single-use, disposable, and non-biodegradable items. By doing that, you may be able to decrease the amount of waste you produce on a daily basis.
Recycle your items wherever possible. Separate your items depending on those that can actually be recycled, and those that may not. Before you throw something in the bin as trash, make sure to think about whether the item can be recycled in its entirety or perhaps a part of it can.
Reuse your items as much as possible before you end up replacing them. Only buy essential necessities and choose your products wisely (preferably those with less packaging). Always look for items in your surrounding that can be reused.
Those three ways are very crucial when it comes to achieving sustainable living. At the same time, it helps humans reduce the amount of waste released into the environment.
