To estimate the time it takes for the population of a microorganism to reduce by half, which is given as 0.000027503 of a year, we can convert this quantity into more familiar units, such as seconds, to better understand the duration.
First, let's convert years to seconds:
1 year ≈ 365 days 1 day ≈ 24 hours 1 hour ≈ 60 minutes 1 minute ≈ 60 seconds
Therefore, the total number of seconds in a year is:
\[ 1 \text{ year} \approx 365 \times 24 \times 60 \times 60 = 31,536,000 \text{ seconds} \]
Now, we can convert the given time:
\[ 0.000027503 \text{ years} \times 31,536,000 \text{ seconds/year} \approx 0.866 \text{ seconds} \]
To summarize, the best estimation of the time it takes for the population of this microorganism to reduce by half is approximately 0.87 seconds.
