Explain why an increase in precipitation and in the number of nearby factories has a greater impact on the occurrence of the mariflowers than changes in temperature, length of day, and invasive species.

An increase in precipitation and in the number of nearby factories has a greater impact on the occurrence of the mariflowers than changes in temperature, length of day, and invasive species. This is because the increase of precipitation helps the plants grow all the more sinceprecipitation helps plants to grow.  Water is very important to plant growth. Water helps the plant move nutrients from the soil up through its stems and leaves. Water keeps the plant moist, flexible, and helps the plant make its own food.
