The BoP is essentially the overall ledger of how much rupee was demanded by the rest of the world and how much foreign currency (that is, currencies of all countries) was demanded by Indians. The BoP is divided into two “accounts” — current and capital. Current account refers to all transactions that are related to current consumption; capital account refers to transactions for investment purposes.
Each bucket is sub-divided into smaller buckets. This allows policymakers and analysts to better understand the dynamics of the relative demand for rupees (by foreigners) and forex (among Indians). All transactions involving export or import of goods (cars, gadgets etc) are logged under the “trade account” within the current account.
But people also trade in “invisibles”. Essentially, this refers to export and import of services (such as an Indian company selling software to an American firm, or a European bank providing financial services to some Indians, or simply Indians working abroad sending back money to their families in India). The capital account, on the other hand involves investments (such as an Indian buying land in the US, or a Japanese firm investing in the Indian stock exchange) as well as exchange of loans between India and other countries.

Ecotone is a zone of junction between two or more diverse ecosystems. For e.g. the mangrove forests represent an ecotone between marine and terrestrial ecosystem. Other examples are – grassland, estuary and river bank.

Characteristics of Ecotone
o It may be very narrow or quite wide.
o It has the conditions intermediate to the adjacent ecosystems. Hence it is a zone of tension.
