What are macromolecules that contain carbon, hydrogen, oxygen, and nitrogen, needed by the body for growth and repair?

I'm sorry to hear that. i will try to answer your other questions if it is within my ability. : )answers: my favourite colour is black.my favourite food is pasta.my favourite school subject is english, but i do also like lunch time.my least favourite subject is history as well as geography. i have currently garnered a quite equal hatred for both of the subjects.what about you? well, you for the points. : )

It's either -limiting factors or -scarce resources but i'd go with my first answer since the food and water are abundant they really aren't scarce
