|
Plants get energy from glucose produced in the soil and animals get energy directly from sunlight

|
Plants do not require energy because they do not move, and animals get energy by performing exercise

|
Plants break down the glucose they produced in photosynthesis, and animals get energy from eating other organisms

Detailed explanation-1: -In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
Detailed explanation-2: -Organisms acquire energy by two general methods: by light or by chemical oxidation. Productive organisms, called autotrophs, convert light or chemicals into energy-rich organic compounds beginning with energy-poor carbon dioxide (CO2). These autotrophs provide energy for the other organisms, the heterotrophs.
Detailed explanation-3: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Detailed explanation-4: -By breaking the chemical bonds in glucose, cells release the stored energy and make the ATP they need. The process in which glucose is broken down and ATP is made is called cellular respiration .
Detailed explanation-5: -During respiration, glucose plus oxygen yield carbon dioxide, water, and energy. This way of generating energy from glucose in animals, mirrors what occurs during photosynthesis in plants. Together, respiration and photosynthesis make a cycle of life.
