The two examples of organisms that differ greatly in their biotic potentials are -
1. Humans and orangutans - These have low biotic potential as they produce only one or two off springs at a time. They have long gestation periods and limited time span to produce offsprings.
2. Bacteria and Scorpio- These organisms have high biotic potential as they can produce thousands of offspring at a time. They also have a short gestation time, so throughout their life, they produce more offsprings.
