Ecology VocabularyAll the words we need to know to talk about the systems
present in the world around us!
Ecology:The study of living things and the way they live in
their environment.
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
Environment:
The set of living and non-living things that make up a region.
Habitat:
The place where an animal or plant lives.
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 not be visible in the picture, make inferences!
Work with your neighbors if you would like
Picture #1: Pacific Tree Frog in Blackberry Bush
Picture #2: Douglas’s Squirrel in Douglas Fir Forest
Energy FlowHow does energy move through an ecosystem?
Where does the energy in your body come from?
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!
Food ChainsA 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!
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
Labeled Food Chain
ProducerPrimary Consumer
Secondary Consumer
Energy is passed along the food chain.
Food Chains
Decomposer: a living organism that helps to break down dead organisms.
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!
Food Webs
Herbivore:Animal that eats only plants.
Carnivore:Animal that eats other animals.
Omnivore:Animal that eats plants and other animals.
Food WebsScavenger:
an animal that eats decaying animals and plants
Activity: Food Chains in Food Web
Key:Top predator: HawkProducer: Marsh Grass, CattailConsumers: Grasshopper, Cricket, Shrew, Frog, Snake, HawkPrimary (1o) consumer: Grasshopper, CricketTertiary (3o) consumer: Snake, HawkHerbivores: Grasshopper, CricketCarnivores: Shrew, Frog, Snake, Hawk
What is another name for a primary consumer?
Fox & SunCreate a food chain to explain why a fox is
reliant on the Sun. Write it in your note blanks, and include:The sunA producerA primary (1st level) consumerThe fox
Fox and the SunFood chain:
Sun Grass RabbitFox
Fox and the Sun
Now turn your chain into a web!
Add:1. One more producer
2. One more primary (1st level) consumer
3. One more secondary (2nd level) consumer
4. One tertiary (3rd level) consumer Hint: 3rd level gets energy from the 2nd level!

Could you add more arrows?? Try!!•Food webs are MESSY, because ecosystems are complicated
