Question

how do organisms use energy, according to the first law of thermodynamics? animals have more energy than plants because they generate more heat. heterotrophic organisms, or consumers, create energy using the food they consume. all organisms break down molecules to convert chemical energy into kinetic energy. plants transform light energy into chemical energy by photosynthesis. plants destroy energy when they produce fruits, so the energy is no longer available in any form.

Explanation:

The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another. Organisms break down molecules (such as glucose) through cellular respiration to convert the stored chemical - energy into kinetic energy for movement, growth, and other life - processes. Photosynthesis in plants is also a form of energy conversion from light to chemical energy. Energy is not created by heterotrophs or destroyed by plants producing fruits. Comparing energy amounts between animals and plants based on heat generation is not related to the first law in this context.

Answer:

All organisms break down molecules to convert chemical energy into kinetic energy.
Plants transform light energy into chemical energy by photosynthesis.
