What are the abiotic components in an ecosystem ?

In an ecosystem in abiotic components which of the following occur

Assertion (A) : Different habitats had different physical and chemical conditions. Reason (R): Physicochemical (abiotic) components characterize the habitat of an organism.

Assertion:- Biotic conponents are as important as abiotic components for determination of habitats in various biomas. Reason:- Interaction between biotic component and physico-chemical components determine the specific regional and local variations of biome.

The key elements that lead to mean variation in the conditions of different habitat, are :- (A) Temperature, water, light and soil (B) parasite, pathogen, predators & competitors of the organism (C) The physico-chemical (abiotic) components characterise the habitat of an organism

Assertion : At climax stage , perfect equilibrium between abiotic and biotic components area cannot be observed. Reason: This is due to autogenic and allogenic succession.
