Answer 1

The correct option is C biosphere

An ecosystem is defined as a functional unit of nature. In this, living organisms interact with each other as well as with the surrounding physical environment. Ecosystem varies in size from small pond to a big ocean. However, boundaries between one ecosystem and another are indistinct and overlapping therefore, all ecosystems on the earth are joined together to form a single global ecosystem known as biosphere.

Population is a group of organisms (same species) in a well defined geographical area, share or compete for similar resources, and potentially interbreed.

Species is the most basic unit of classification and biodiversity. It constitutes organisms having similar characteristics and can produce fertile offsprings.

Community is an interacting group of various species in a particular location.
