Solution

The correct option is A True
Energy accumulated by plants or the producers in an ecosystem is called primary production. The total energy produced during photo synthesis is the Gross primary production and is represented by PG or A and energy left after respiration and stored as organic matter in the producers is the Net primary production represented by PN. Net primary consumers actually represent food potentially available to primary consumers which feed upon plants. The primary consumers, therefore, take in chemical potential energy in the form of plant food.
