3. The mechanism in which organisms best suited for their environment survive<br> and reproduce.
lys-0071 [83]

The mechanism in which organisms best suited for their environment survive

and reproduce <u>NATURAL SELECTION.</u>

<u></u>

Explanation:

When individuals in a population compete for resources or live in their environment, the individuals with the slightest advantage over the others have an increased chance of reaching maturity and  reproducing to passing down their genes to the next generations.

Natural selection works on the variations of the population to ‘select’ the best alleles of genes in the population that offer an advantage in ‘survival for the fittest’. This how natural selection fits a population to its environment. The greater the variation within a population, the higher its capacity to adapt to changes in the environment.

To answer this question you must break apart the words given on the right.
“Eco” means life and production. So an ecologist would be someone who studies life and it’s processes. So the correct answer for the first blank would be C. Life Science.

A chemist is one who interacts with day to day elements and sciences that is tactile. So the most appropriate answer would be B. Physical science.

A geologist is someone who studies the earth. As the part of the word “geo,” meaning earth, suggests. So the correct answer here would be A. Earth science.

Finally, “Astro” means space .Astrology is the study of the stars and the sky, for example. So, D. Space science would be the best answer for an astronaut.

I hope all of these are helpful. :)
