Answer:
50% is the birth rate of the Hydrilla plants population.
Explanation:
Number of Hydrilla plants that are available in the pond is 20
Number of new Hydrilla plants that were added in a year is 10
The birth rate of the population can be calculated with the help of formula
Birth rate=New plants/Old plants * 100
=10/20*100
=50%
Thus the birth rate of the population becomes 50%
