The right answer is ISOTONIC contraction (not isometric)
During an isotonic contraction, the length of the muscle varies but not the tension. For example, an athlete achieves (approximately) isotonic contraction when he lowers an extremely heavy weight, at a slow and constant speed, against maximum resistance.

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.
