energy packed foods

Fuels such as coal, petroleum and natural gas, which undergo combustion (burnt in air either alone or after mixing with another substance) and release energy are needed for the working of machines. The energy released keeps the machines working. More is the energy rel..

While studying the biotic components in an ecosystem we have realised that food prepared by green plants is consumed by a series of consumers, both herbivores and carnivores, and finally broken down into their elements and released back into nature by decomposers in nature. The nutritiona..

The components of food are certain organic substances and minerals found in food. They are called nutrients. Nutrients provide the body with energy and enable it to grow, repair and maintain itself. Hence it is important that we understand the exact role of nutri..

A food chain is a series of steps by which energy is obtained, used, and transformed by living things. For example; sunlight helps plants to grow, the plants are eaten by cattle, and lions eat the cattle. All living organisms of the biosphere are related to each other by a ..

Introduction - All living creatures need food. The food is consumed so that energy is obtained. The energy is utilised by the body for various purposes like locomotion, conduction of impulses, repair of damaged tissues, building of cell materials, etc. The su..

"Pyramid of energy is a graphic representation of the amount of energy trapped per unit time and area in different trophic level of a food chain with producers forming the base and the top carnivores at the tip". Pyramid of Energy in a Food Cha..

Although matter circulates, energy cannot be reused indefinitely. Solar energy is converted by the photosynthetic producers (plants) into chemical energy in the form of plant carbohydrates. Herbivores consume the plant carbohydrates and so this chemical energy..
