The largest animals that represent the top of the trophic pyramidThe gradual reduction in energy content, increase in body size and reduction in number of animals, that occurs the higher you go up the food chain. At the base of the pyramid are a vast number of high-metabolism, tiny creatures and at the summit, are the top predators. To be stable, the pyramid has to have creatures at all levels. More. These are the final building blocks in ecosystemHow ecosystems function An ecosystem is a community of lifeforms that interact in such an optimal way that how ecosystems function best, is when all components (including humans and other animals) can persist and live alongside each other for the longest time possible. Ecosystems are fuelled by the energy created by plants (primary producers) that convert the Sun's heat energy More structures for maximum entropy productionWhere an ecosystem achieves a steady stable-state with the maximum possible number of species and there is very little free surplus energy because it is all consumed inside biological processes. Entropy dictates that all matter moves towards chaos but animal life enables ecosystems to continually move in the opposite direction. Reaching a state of maximum entropy production is essential for More. Megafauna can be measured at any spatial scale. The largest animal that ever lived on Earth is the Blue Whale. In a grassland, spiders could be considered megafauna The term is generally reserved for animals larger than insects.
