Ecology Vocabulary

1. Ecology Vocabulary All the words we need to know to talk about the systems present in the world around us!

2. Ecology: • The study of living things and the way they live in their environment.

3. Ecosystem All the living and non-living things in a particular area. • Biotic Factors: • Living, once living made by living things • Abiotic Factors: • Non-living

4. Environment: • The set of living and non-living things that make up a region.

5. Habitat: • The place where an animal or plant lives.

6. Using Ecology Vocabulary • Use the pictures on the slides to answer the questions in your noteblanks. Use the vocabulary you just learned! • Some answers will notbe visible in the picture, make inferences! • Work with your neighbors if you would like

7. Picture #1: Pacific Tree Frog in Blackberry Bush

8. Picture #2: Douglas’s Squirrel in Douglas Fir Forest

9. Energy Flow How does energy move through an ecosystem? Where does the energy in your body come from?

10. Energy Source: The Sun • All the energy within our food originates from the sun – • Plants make the sun’s energy into sugar • All other animals must consume sugars to get energy It comes from the sun!

11. Food Chains • A food chain shows where organisms get their energy from in a particular habitat. • The arrow points in the direction of the energy flow. • Energy is passed along the food chain • Now make a food chain!

12. Food Chains • Producer: • Makes their own food from carbon dioxide and water using the energy from sun. • Primary (1st level) Consumer: • Eats (Consumes) producers • Secondary (2nd level) Consumer: • Eats primary consumers

13. Labeled Food Chain Producer Secondary Consumer Primary Consumer • Energy is passed along the food chain.

14. Food Chains • Decomposer: • a living organism that helps to break down dead organisms.

15. Food Webs • In all healthy habitats, more than one organism normally eats/is eaten by other organisms. • A food web includes many food chains which interlink with each other. • Make a food web on your page with the pictures and info you have!

16. Food Webs • Herbivore: • Animal that eats only plants. • Carnivore: • Animal that eats other animals. • Omnivore: • Animal that eats plants and other animals.

17. Food Webs • Scavenger: • an animal that eats decaying animals and plants

18. Activity: Food Chains in Food Web Key: • Top predator: Hawk • Producer: Marsh Grass, Cattail • Consumers: Grasshopper, Cricket, Shrew, Frog, Snake, Hawk • Primary (1o) consumer: Grasshopper, Cricket • Tertiary (3o) consumer: Snake, Hawk • Herbivores: Grasshopper, Cricket • Carnivores: Shrew, Frog, Snake, Hawk • What is another name for a primary consumer?

19. Fox & Sun • Create a food chain to explain why a fox is reliant on the Sun. Write it in your note blanks, and include: • The sun • A producer • A primary (1st level) consumer • The fox

20. Fox and the Sun Food chain: Sun Grass Rabbit Fox

21. Fox and the Sun • Now turn your chain into a web! • Add: • One more producer • One more primary (1st level) consumer • One more secondary (2nd level) consumer • One tertiary (3rd level)consumer • Hint: 3rd level gets energy from the 2nd level!

22. Fox and the Sun Sun Grass Rabbit Fox Blackberries Mouse Snake Hawk • Could you add more arrows?? Try!! • Food webs are MESSY, because ecosystems are complicated
