In the latter case the resistance is caused by dissipation of mechanical energy when the configuration or the direction of flow is sharply changed, by the formation of vortices and secondary flows as a result of the flow breaking away, by the centrifugal forces, etc.
Animals depend on plants for food as plants produce food and energy which animals can't, so, herbivores eat plants to get energy, carnivores eat herbivores and other carnivores for energy and omnivores eat all four, plants, herbivores, carnivores and also other omnivores for energy.
3Chlorophyll helps plants to trap light energy to photosynthesise. 4 Plants can photosynthesise in the absence of water. 5 Plants get energy from the sugar they make. 6 Plants are food producers. 7 Not all animals are food consumers.8 Some food consumers feed on plants only.9 Monkeys are an example of omnivores.10Carnivores are organisms that feed on both plants and meat. How Do Organisms Get Their Energy? Look at the following statements and tick in the columns below if they are true or false.
