Which of the following is not a feature of typical r-selected species ?

Options

A. High rate of reproduction
B. Large number of offsprings in a single mating
C. Small sized offsprings
D. Long life span

Answer

To determine which of the following is not a feature of typical r-selected species, let's analyze each option based on the characteristics of r-selected species:

1. **High rate of reproduction**: R-selected species are known for their high reproductive rates. They produce many offspring in a short period of time to increase their chances of survival in unstable environments. This is a feature of r-selected species.

2. **Large number of offspring in a single mating**: R-selected species typically produce a large number of offspring during each reproductive cycle. This characteristic is also true for r-selected species.

3. **Small sized offspring**: R-selected species usually have small-sized offspring. This allows them to produce more offspring and increases their chances of survival. This characteristic is consistent with r-selected species.

4. **Long life span**: R-selected species generally have a short life span. They tend to mature quickly and reproduce early in their life cycle, but they do not live long. This characteristic is not typical of r-selected species.

Based on this analysis, the option that is not a feature of typical r-selected species is:

**Long life span**.
