Explanation:
biotic factors are the living components of an ecosystem (producers, consumers, decomposers). They all have some effect on population dynamics, producers (plants) are eaten and can make clean air, consumers (ex. ants, badgers, bears, fish, humans) rely on producers for food, and decomposers (bacteria, earthworms, fungi, flies) decompose things like dead plants and animals.
The first one is atoms cause they are all the same type of particles. The blue one is the molecules that is not compound cause they aren't connected to each other. The other two are compound cause two atoms of two different elements are bonded together.

The other options refer more to Romanticism than to Realism. </span>
