food chain what is a pyramid of number and pyramid of energy

Pyramid of Energy - "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 ti..

Ecological pyramids are also called 'Eltonian pyramids' after C. Elton. Charles Elton (1927) developed the concept of ecological pyramids who noted that "the animals at the base of a food chain are relatively abundant while those at the end are rela..

>Pyramid of Numbers in a Aquatic Ecosystem So, the producers are smallest sized but maximum in number while, top carnivores are larger in size but lesser in number, so these cannot be used as prey by another. Hence the pyramid of numbers i..

Pyramid of numbers is the graphic representation of number of individuals per unit area of various trophic levels stepwise with producers forming the base and top carnivores the ti..

Food Chains - 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 bi..

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..

In a food chain, a) there is repeated eating in which each group eats the smaller one and is eaten by the larger one. Thus, it involves a nutritive interaction between the biotic components of an ecosystem. b) the plants and animals which depend successively on one another form ..
