5/26/2020 0 Comments Ecosystems and EnergyBelow you will find some videos and articles that discuss ecosystems and energy. Remember an ecosystem is all the living and nonliving parts of an environment. If you have been working on Canvas you know that the energy in ecosystems starts with the sun. The sun gives energy to plants (producers) and the plants give energy to the animals that eat them (consumers). Some animals eat the animals that eat the plants. These are called secondary consumers. Here are some key words to know: Producers make energy from the sun (plants) Consumers eat to get their energy Herbivores eat only plants Carnivores eat only other animals Omnivores eat both plants and animals Decomposers break down dead materials and recycle that energy back into the ecosystem All of these plants and animals can be linked together into food chains and food webs to show who passes their energy on to whom. We use arrows to show the direction of energy. Sun --------------> grass ------------>grasshopper ----------->bird ------------>fox For all food chains on Earth the sun is the source (start) of energy. The grass is a producer (making energy from the sun). The grasshopper eats the grass and gets its energy. The grasshopper is an herbivore because it eats plants. The bird eats the grasshopper and gets its energy. The bird will sometimes eat plants and sometimes animals so it is an omnivore. The fox eats the bird and gets its energy. The fox eats animals so it is a carnivore. The arrows show the direction the energy moves. You can read the food chain like a run on sentence by replacing the arrows with "gives energy to". Sun gives energy to grass gives energy to grasshopper gives energy to bird gives energy to fox. Here are some videos that explain food chains and food webs.
