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

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

Detailed explanation-1: -How do organisms get the energy they need? Plants get energy from fertilizers, and animals get energy by drinking water. Plants get energy from glucose produced in the soil, and animals get energy directly from the sunlight.
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: -Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.
Detailed explanation-4: -Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use. Cellular respiration consists of three metabolic processes: glycolysis, the Krebs cycle, and oxidative phosphorylation.
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.
