Answer 1

The correct option is D I and II only

An ecosystem is made up of abiotic components or abiotic factors which are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors include water, light, radiation, temperature, humidity, atmosphere and soil.

Biotic components are the living things that shape an ecosystem. Biotic components usually include Producers (vegetation), Consumers and Decomposers. Therefore only temperature and humidity are included under Abiotic factors. Hence, the correct answer is option D.
