Answer
A is true but R is false.
Reason — A is true as an ecosystem indeed has two components: biotic and abiotic. Both are interdependent, meaning they depend on and affect each other for survival and functioning.
R is false as biotic components depend not only on abiotic factors, but also on other biotic components.
Therefore, A is true but R is false is the correct option.
