Which was Charles Darwin's contribution to the study of biology? O He was the first person to recognize that organisms change over time.
O He believed that organisms adapted through the inheritance of acquired traits.
He explained how traits are passed from parents to offspring.
O He proposed that natural selection is the primary mechanism of evolution.

He proposed that natural selection is the primary mechanism of evolution.

Explanation:

Lets look at this question like this:

If you have a white deer in a green forest, the wolves who prey on deer would automatically go for that white deer. The white deer is easier to locate rather one who would blend in their environment. (A brown deer) With the theory of natural selection, the survival of the fittest would make it in their environment. Passing their genetics to their offsprings.

He proposed that natural selection is the primary mechanism of evolution.

Explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
