Plants give off oxygen (that we breathe)and breathe in our carbon dioxide that we exhale
In biology, the biotic factors pertain to the living components of Earth while the abiotic factors are those non-living chemicals and physical factors. The only choice that is not an interaction between biotic and abiotic factors is the third choice, "C. male elk fighting over a female".
Q: this picnic table was made from fallen trees in a local forest. is this picnic table a biotic or abiotic factor? explain your answer.
A: the answer would be biotic because the term biotic means that something is living or had lived before. as you can see, the table was made by fallen trees in the local forest. that means it lived before the tree was fallen and carved into a picnic table.
