Question

Energy decreases along a food chain in an ecosystem. How is this explained by the law of conversation of energy? (A) living things change energy into matter (b) the energy is changed to a different form (c) only small amounts of energy can be destroyed at a time (d) energy is used up when living things conduct life processes

Answer 1

B. the energy is changed into a different form

...because the law of conservation of energy states that energy cannot be created or destroyed, it only changes form. Energy can't just disappear, therefore, it is converted into a different form as it passes through the food chain.
