• B. Matter only
• C. Biotic factors only
• D. Matter and energy only

Answer 1

The correct option is D Matter and energy only

A living being or an organism acts as an open system. It exchanges energy and matter constantly with its surroundings to sustain its living. A part of energy is either utilised, converted or transferred through an organism's action or interaction. Organisms feed and consume matter either directly or indirectly. The surrounding offers food and shelter to the organism. As a result, if it is taken out of its surroundings, the organism will perish. In other words, both the organism and its surroundings influence each other to sustain life. Ecology is the study of this mutual interaction.
