A_______ is the smallest unit that can carry on all the processes of life
--------------
"In looking at nature, never forget that every single organic being around us may be said to be striving to increase its numbers."- CHARLES DARWIN, 1859
ANSWER BRIEFLY
1. How can natural selection reduce competition between species?(2-3 sentences).
2. How do communities and ecosystems respond to changing environmental conditions? (Answerable only by a scientific terminology (two words) I don't need sentences or paragraph for 2).
3. How do species interact (in the context of ecology ha, so scientific term)?
Misconception: Humans can’t negatively impact ecosystems, because species will just evolve what they need to survive.
