Explanation:
agar is filled with sugars and basic amino acids that will allow bacterial and fungal agents to rapidly grow and multiply
This is an example le of commensalism.The burdock seeds benefit and the cow is unharmed.
(Initial individuals + newborn individuals) - dead individuals = total individuals
Growth rate = (total individuals/initial individuals) * 100
Population growth rate = new percentage minus 100%
Calculations
(1000 + 500) - 200 = 1500 - 200 = 1300
Growth rate = (1300/ 1000) * 100
= 1.3 * 100
= 130%
Population growth rate = 130% - 100%
= 30% per year if it is uniform
