Answer: False
Step-by-step explanation:
The population growth rate is dependent on how many organisms of the SAME species are added, not how many NEW species. A population, according to biologydictionary.net, is "the number of organisms of the same species that live in a particular geographic area at the same time, with the capability of interbreeding."
There are human populations, bird populations, apple tree populations, etc. Remember, a population is a group of the SAME species living in the SAME area.
