The food we eat acts as a fuel to provide us energy to do work. Thus the interactions among various components of the environment involves flow of energy from one component of the system to another. The autotrophs capture the energy present in sunlight and convert it into chemical energy. This energy supports all the activities of the living world.1. Energy is first absorbed by  ________.a. autotrophsb. heterotrophsc. decomposersd. None of these2. What is the ultimate source of energy in an ecosystem?a. Sunb. Waterc. Aird. Food3. In an ecosystem, the energy flow is alwaysa. Always bidirectionalb. Always unidirectionalc. In any directiond. Always down directional4. How can we indicate the accurate energy passed at each trophic level?a. By the help of pyramid of numberb. By the help of pyramid of biomassc. By the help of pyramid of energyd. By the help of pyramid of food web5.
