Which example describe biotic and abiotic factors interacting with the environment?
a

oxygen circulating in the atmosphere
b

sunlight shining through a window
c

a valley filling up with rain water
d

dolphins communicating with each other

Greetings!

First and foremost, let's define abiotic & biotic factors.

Abiotic factors are materials in an ecosystem that are non-living.

ex) rocks, wind, water, sunlight, etc.

Biotic factors are living organisms, anything with cells that can interact with it's environment.

So the correct answer would be A. Oxygen circulating throughout the atmosphere.

Hope this helps, have a nice day!

D) dolphins communicating with each other

The reason I got this answer is because if you look on the assignment it says, "dolphins communicating with each other by using sound waves through the water." Dolphins are biotic while water is abiotic.
