1. Food Chains Food Chain: a simple sequence of feeding relationships. – May include a producer, an herbivore and a carnivore. – Shows the different levels of consumers.

2. Label the producer(s), the herbivore(s), and the carnivore(s). Are there any omnivores in this picture?

3. Food Webs Food Web: complex sequences of feeding relationships. Many food chains coming together!

5. Food Chains & Food Webs The arrow points to the animal that is the consumer. This signifies which direction the energy is flowing! Label which organism is the producer, the primary consumer, secondary consumer, and tertiary consumer.

6. Food Chains & Food Webs Vocab Producer: makes its own food for energy (ex. Plants, trees, grass) Consumer: needs to eat something else for energy (ex. Insects, birds, tiger) – Primary Consumer: eats producers – Secondary Consumer: eats consumers that eat producers – Tertiary Consumer: eats consumers that eats other consumers Herbivore: only eats plants Omnivore: eats both plants and meat Carnivore: only eats meat Scavenger: an animal that feeds on dead animal matter. Decomposer: breaks down dead plant and animal matter (decomposes organic matter)

7. Name the ecological relationship that the following slides represent.

8. Mutualism

9. Commensalism

10. Parasitism

11. Predation

12. Competition

13. Ecological Relationships Symbiotic Relationships – Mutualism: both organisms benefit – Commensalism: one organism benefits, the other organism is unaffected – Parasitism: one organism benefits, the other organism is harmed Other Relationships – Predation: one organism hunts and kills another organism for food (predator-prey relationship) – Competition: two organisms compete or fight for resources (shelter, food, mate)
