Energiavajadus refers to the amount of energy an organism needs to sustain its life processes. This energy is primarily derived from the food consumed by the organism. The specific energy needs vary greatly depending on factors such as species, age, size, activity level, and environmental conditions. For example, a young, actively growing animal will have a higher energy requirement than an older, sedentary one. Similarly, animals in colder climates may need more energy to maintain body temperature.

The energy required for basic metabolic functions, such as breathing, circulation, and cell maintenance, is known as basal metabolic rate (BMR). In addition to BMR, energy is expended on physical activity, digestion (thermic effect of food), and growth or reproduction. Organisms obtain energy through the breakdown of carbohydrates, fats, and proteins in their diet. These macronutrients are converted into adenosine triphosphate (ATP), the main energy currency of cells.

Meeting energy needs is crucial for survival, growth, and reproduction. Insufficient energy intake can lead to malnutrition, reduced activity, impaired immune function, and even death. Conversely, excessive energy intake can result in obesity and associated health problems. Therefore, understanding and meeting an organism's energyvajadus is a fundamental aspect of its biology and ecology.
