Be familiar with these facts about living things: Plants​ are the primary source of matter and energy in most food chains. A human is an ​omnivore​. Fungi​ are decomposers. A ​food chain​ shows the flow of energy from a producer to one or more consumers. A good example of ​energy flowing from one living thing to the next​ is carnivores store some of the energy transferred from animals they eat. Draw a picture of each item to illustrate this food chain: grass
mouse
hawk Sunlight​ is the main source of energy for most ecosystems on Earth. Most​ ​bacteria​ are helpful. Plants make food by the process of ​photosynthesis​. One benefit of ​decomposers​ is they add nutrients to the soil. Be prepared to write ​complete, detailed sentences​ to these questions: 1. What is an ecosystem? List one example. 2. Describe three ways that microorganisms are helpful.
