General Information
SC.7.P.10.2-
Light (visible) can either be refracted, reflected, or absorbed. Light is refracted when it passes into another material of a different density. When light is refracted it looks bent. An example of this is when you put a pencil in a cup of water and it looks bent from when it goes into the water. Light is reflected when it it changes direction as it "bounces off" another material. All objects that you see reflect light because color is just light reflected to your eyes. Light is absorbed when the energy of the light is converted to heat. An example of this is any object in which no light gets through such as a table, or a book.
SC.7.L.17.1
All energy comes from the sun. The produces, which are plants, use the suns energy to make food for themselves in a process called photosynthesis. Plants also make nutrients that consumers eat. Consumers, which are the next link in the food chain, which eat plants, animals or both. They do not make their own food and get their energy from the things they eat. There are three types of consumers, primary, secondary, and tertiary. Primary consumers are herbivores and eat plants to get their energy. The secondary consumers are carnivores who get their energy from other animals or a few omnivores. The tertiary consumers are those who eat the primary and secondary consumers. Another type of consumer is the omnivore who eats both plants and animals. They are either secondary and tertiary consumers. The final link is the decomposers. Decomposers are organisms that break down the nutrients in dead things and return it to the soil for producers to use. A few examples of producers would be grass, trees, and any plant. A few examples of primary consumers would be squirrels, rabbits, mice, cows, and horses. A few examples of secondary consumers would be snakes, hawks, and wolfs. A few examples of tertiary consumers would be bears, humans, and sharks. Humans and bears are also omnivores because we both eat plants and animals. A few examples of decomposers would be mushrooms, funguses, and bacteria.
