D) Amount of precipitation
Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.
Species strategies to survive and successfully reproduce define three basic survivorship curves. <em>The survivorship curve </em><em>type III</em><em> is the one that best represents the Dandelion plants.</em>
------------------------------
According to the species strategies to survive, reproduce, and ensure their reproductive success, we can mention three basic curves,
<u>Type I.</u>
- Mortality often occurs at the end of the cycle, representing species with low mortality.
- Organisms exhibiting this type of survivorship curve have long life cycles and high probabilities to survive until they are old enough.
- These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.
<u>Type II.</u>
- The probabilities of dying are equals all along the cycle, at any age interval.
- The number of dead individuals remains constant from the beginning to the end of the life cycle.
- These species have reduced offspring, and they ensure their reproductive success by providing some significant parental care.
<u>Type III.</u>
- Significant mortality during the early stages of life.
- Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life.
- These species produce large offspring at the same time, but they provide little or no parental care.
- The reproductive success of these species depends on the number of descendants and not on the parenting time spent.
According to this information, and the characteristics of the <em>Dandelions, we might assume that this species is represented by type III curve.</em>
