Question

Quizplus · Accepted Answer

The fact that only 1% of tadpoles survive to reproduce indicates that the bullfrog population is experiencing low levels of recruitment. This means that the population growth is limited by factors that prevent new individuals from joining the population, such as predation, disease, competition, or environmental conditions. It does not imply low environmental resistance, unlimited growth, or exponential growth.
