Option (B) Interdependent is the correct answer.
How do organisms live in an ecosystem?
An ecosystem comprises two components ie. living and non-living. Living components include all the organisms such as animals, humans, plants, etc., and nonliving components include soil, air, water, etc. All the organisms which live in the same ecosystem are interdependent, as well as dependent on nonliving components too.
