|
|
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: -Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
