To solve this, we analyze each option:

• "Ecosystem" is defined as a system where biotic (living) and abiotic (non - living) factors interact.
• "Zoo" is a place for keeping animals, not a system of biotic and abiotic factors.
• "Species" is a group of similar organisms, not a system of factors.
• "Microscope" is a tool for viewing small objects, not related to this system.

So the correct term is "Ecosystem".
