Question

Compared with pure cultures grown in the lab, microbes in nature usually experience a wider range of environmental conditions, more variation in conditions over time, and more contact with other organisms. Therefore, the same organism in nature will __________.
A-carry out completely different metabolisms than in pure culture
B-typically grow slower than in pure culture
C-typically grow faster than in pure culture
D-typically grow only on surfaces

Answer 1

Answer:

The correct answer is B-typically grow slower than in pure culture

Explanation:

In nature, microbes experience lots of challenges like challenges to get space, to live, to get food, to adapt to the changing environment, to get protection from their pathogens and predators, etc. So these all challenges affects the growth rate of microbes.

In pure culture only one type of bacteria is grown on a nutrient-rich media and a steady environment is given to them to grow. In pure culture, there are no predators and competitors for microbes.  

So all this provide favorable condition for a microbe to flourish in a pure culture so the growth of an organism in pure culture is higher than in nature. So the correct answer is B.
