Alexxx [7]

While the pink flowers tripled because some factors in the environment were favorable for its growth.

From the question, it was mention that the botanist noticed at first purple flowers had more population than the pink flowers and that changed after 10 years when the population of the pink flowers tripled and purple flowers were nearly gone. Some of the causes that could be responsible are:

1. Disease and pest attack on the purple flowers.

2. The pink flowers developed a good survival mechanism even in adverse conditions.

3. Environmental stress could also come into play on the purple flowers.

4. Climate which initially supported the growth of the purple flowers had changed. Because variations exist in plants and the ideal conditions necessary for plant growths and proliferation varies among plants.
