Transcript of Food Chains (4th Grade Science)

Food Chains Producers Consumers are animals that eat producers or other animals. Consumers Decomposers are the final link in the food chain. A decomposer breaks down dead plants and animals so they can become food for plants. Worms, bacteria, and fungi are all decomposers. Decomposers In Conclusion, a food chain shows how food and energy are transferred from one organism to another. Summary Organisms that can make their own food are called producers. They do this by using light energy from the sun, a process called photosynthesis. The Food Chain Every living thing needs energy to live. A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life because they can make their own food and ends with animal-life. Primary consumers are next in the food chain link after producers. Herbivores, or plant eaters, are the first consumer of the energy produced by plants. Primary Consumers Secondary consumers are carnivores, or meat eater, and are the third link the food chain. They obtain energy by eating herbivores. A secondary consumer can also be an omnivore, an animal that consumes plants and animals. Secondary Consumers
