The wrong statement is C. <em>Individuals with Type Il survivorship exhibit high survivorship throughout
</em>
their life cycle.
Explanation:
Different species have survival curves differently shaped. In general terms, there are three different survival curves.
- Type I. Organisms do not tend to die when they are young or middle-aged, but they do when they are old. These species, in general, have a few descendants and parents provide much parental care to ensure their progeny survival. Typical of K selected species.
- Type II. Organisms that have more or less the same probabilities of dying in each age interval. These organisms can also have a few descendants and they can provide significant parental care.
- Type III. Only a few individuals survive their first period of life or their firsts years. However, the lucky ones to reach a certain age generally have a long life. These organisms have a lot of descendants at the same time, but they do not provide much parental care. Typical of r selected species.
