The first law of thermodynamics states that energy cannot be created or destroyed. Plants do not create energy, but rather they harness it from the sun. They convert the light energy in the photons of sunlight into chemical energy in the bonds of carbohydrates they make. We get energy from consuming plants when we acquire and break down these chemical bonds in carbohydrates of plants for our cellular processes.
The first law of thermodynamics deals with the conservation of energy, stating that the total energy of a system remains constant. In other words, it is not possible to create or destroy energy, energy only changes from one state or another. Therefore, it is false to affirm that plants create energy. Plants use energy from sunlight during photosynthesis to convert carbon dioxide and water into glucose.
Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control.
<u>Without a water supply, organisms in aquatic and land habitats will die. Organisms without access of water cannot access oxygen, and as a result of that, they would die. Oxygen is needed for organisms in order to survive. Water also helps insulate the living environment for these organisms.</u>
