Answer:
Carbon, hydrogen, oxygen, nitrogen, phosphorous, and sulfur.
Explanation:
Macromolecules such as carbohydrates or lipids are made of a selection of these six elements. Carbohydrates are made out of carbon, hydrogen, and oxygen--or "CHO" for short. Lipids are made out of carbon, hydrogen, and oxygen as well. Proteins are made out of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur (CHONs, the s is lowercase because sulfur does not usually appear in proteins). Nucleic acids are made out of carbon, hydrogen, oxygen, nitrogen, and phosphorous (CHONP).

allows them to control all of the variables involved.
Explanation:
Ecologists often use modelling instead of field studies because it allows them to control all of the variables involved.
It is very difficult or nearly impossible to control the variables when we carry out field studies.
Ecology is a science that studies the relationship between organisms and their environment.
- A model is an abstraction of the real world.
- It helps us take a part of the real world and understand them better.
- Since we are in control of a model, it is possible to change some parameters to help better understand their controls on others.
- Models are simply flexible because they be controlled and better understand the complex realities posed during a field study.
