False. To determine population size, you would need to send out letters requesting you write down how many people are living in your household. Have a great/nice day :)

Correct answer: True

It is better to determine population by direct observation because it gives the exact population count. It this method of observation each organism is counted. It will take a longer time period to count the population by direct observation, but it give exact and correct count.

For example- Direct method, which could be used to know population size are how much food they ate or by knowing the sample of the population.
