5. Ecosystem-Day 1 An ecosystem includes all of the living things in an area, plus their surroundings, plus all the ways in which they interact with each other.
6. Producers: Photosynthesis- Day 1 Producers are the beginning of a simple food chain. Producers are plants and vegetables. All energy comes from the Sun and plants are the ones who make food with that energy. This is because they produce their own food! They do this by using light energy from the Sun, carbon dioxide from the air and water from the soil to produce food - in the form of glucouse/sugar.
12. Food Chain/Web-Day 4 Food chains are models that illustrate how plants and animals in an ecosystem are linked by their feeding relationships. Plants and animals are usually part of several food chains simultaneously. Food webs are models that show how different food chains combine to form a more complex system.
