Hello!
I am not given any options, but I can explain the question to you.
A biotic factor is anything that is living in the ecosystem, such as animals, plants, fungi, and bacteria.
An abiotic factor is anything that is not living but the ecosystem needs to thrive, such as sunlight, oxygen, good temperature, living space, etc.
For example, let's say we had options below.
A. Sunlight
B. Living Space
C. Moss
D. Oxygen
As you can see, all of our options are beneficial to an ecosystem, but moss is the only one that is living. In this scenario, our answer would be C. Moss, as it is a biotic but not an abiotic factor.
I hope this helps!
