Cassava or tapioca is a popular crop plant across Asia. There are two types of cassava. One type cannot grow in very dry conditions. The other type is drought resistant. If farmers plant the two types of cassava during the rainy season, both types grow.

Predict what will happen to the numbers of the two types of plants if the rainy season arrives regularly for the next three years.
