  (iv) Population

Answer 1

The correct option is B (i) Organism
(ii) Population
(iii) Community
(iv) Biomes

An ecosystem is an integrated functional unit that consists of many successive levels of organization, which can be called the ecological hierarchy. The basic component or the lowest level in this hierarchy is the organism. An interbreeding group of organisms of the same species is called a population. A group of interacting populations forms a community. A community and its physical environment together forms the ecosystem. When many ecosystems that are similar to each other interact with each other on a large scale, it is called a biome. Hence, Biomes are ecological areas with similar fauna and flora adapting to similar conditions.
