Answer: The rock is 2000785 years old.
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = initial amount of the reactant = 800
x = amount of daughter isotope = 600
a - x = amount left after decay process = amount of parent isotope = (800-600) = 200
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
The rock is 2000785 years old.

In addition to this, the high abundance of rainfall also allows the number of predators to increase as a result of which it becomes difficult for them to survive.
From the above condition, it can be generalized that the population of lizard will increase at a much higher rate.
