What is a primary characteristic of Type II growth curves?

Type II growth curves are primarily characterized by a steady, constant growth rate until limited by environmental factors. This type of growth follows a linear pattern where the population increases at a consistent rate, reflecting a balance between reproduction and mortality under relatively stable environmental conditions.

In contrast to exponential growth seen in some populations (as noted in the second choice), Type II growth does not grow exponentially but rather increases in a more predictable and controlled manner. The growth pattern is not marked by rapid oscillations, which would involve fluctuations and instabilities. Additionally, while predation factors may influence a population's growth (as mentioned in the fourth choice), Type II growth is focused on situations where these limiting factors are balanced, allowing for a more stable growth rate. Thus, the primary characteristic revolves around the consistent linear growth under stable ecological circumstances.
