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.
Notice how water moves diï¬ erently through each soil texture.The forest is an ecosystem. Forests are full of living and nonliving things that depend on each other. Trees, ferns, and shrubs grow in the forest. Deer, frogs, lizards, insects, birds, and bears are some forest animals that need these plants.Water, stones, and soil are nonliving things that animals need too.otice how water moves diï¬ erently through each soil texture.The forest is an ecosystem.
