Answer:
The correct answers are: biology & botany.
Explanation:
Natural resources are those that exist without the actions of humans and are elements that help and contribute to the development of different living species (for example, the trees that give us the oxygen we need in order to breath).
For this particular reason, I think that careers in natural resources would be biology (the science that study living organisms) and botany (the science that study plants). Economics and English do not relate to natural resources.
