  1. Created by Mr. Hemmert Food Chains

  2. Science ALCOS • L5.3 Tracing the flow of energy through a food chain • Example: producer, first-level consumer, second-level consumer, and third-level consumer

  3. Food Chains • Every organism needs to obtain energy in order to live. • Plants get energy from the sun, some animals eat plants, and some animals eat other animals. • Living things depend on one another to live.

  4. Food Chains consumer • A food chain is the movement of food energy in a sequence of living things. producer consumer consumer consumer

  5. Food Chain Vocabulary • Consumers that are eaten are called prey. • A consumer that eats prey is a predator.

  6. Prey and Predators • Predators limit the number of prey animals in a habitat. • Ex. Wolves are predators of antelope. They keep the population of antelope from increasing too much, so the antelope don’t eat all of the producers. • Predators often compete for the same prey. This limits the number of predators in a habitat.

  7. Level of Producers • Primary Producers - Organisms that make their own food from sunlight. Primary producers are always the base (bottom) of the every food chain.

  8. Levels of Consumers • First Level Consumers are animals that eat producers (plants). • They are also called herbivores (plant-eaters)

  9. Levels of Consumers • Second Level Consumers eat first level consumers. They are called carnivores (meat – eaters) and omnivores (animals that eat both animals and plants.)

  10. Levels of Consumers • Third level consumers eat second level consumers.

  11. Practice What is the primary producer? _________________________ What is the first-level consumer? _________________________ What is the second - level consumer? ______________________ _ What is the third-level consumer? ________________________
