Answer» Nutrition: Energy required to carry out different life processes is obtained through the process of nutrition. Depending on the mode of obtaining nutrition, organisms are classified as autotrophs or heterotrophs. i. Autotrophs can prepare their own food from simple inorganic sources such as carbon dioxide and water. Examples: Green plants and some bacteria. ii. Heterotrophs cannot synthesise their own food and are dependent on other organisms for obtaining complex organic substances for nutrition. Example: Animals and fungi
