Por ejemplo, la ecología podría estudiar la manera en que un venado interactúa con su entorno: cual es su principal fuente de alimento, el rol que juega en el ecosistema, las adaptaciones que ha desarrollado para vivir en dicho entorno, etc.
Debido a que la materia inerte es considerada un factor abiótico o no vivo, esto no correspondería al área de la ecología. Por ende, este enunciado <u>es falso</u>.

LUCA the last universal common ancestor; it is exist in 3.5 billon years ago in the paleoarchean era, a few hundred million years after the earlier fossils evidence of life.
<u>Explanation:</u>
It is the single celled bacteria like organisms living in volcanic era. The three domain of the life are Archaea, bacteria, Eukaryotas. The observation that member of the single gene family are found in the all three domain of life.
It is suggested that the progenitor gene that give rise to the family member existed in the LUCA , before the time that the three domain diverged.
