2. Unit 2 Review Ecology: study of living things and how they interact

3. Ecosystem: living things and their environment Please pause the audio and try to answer the following questions… What are some non-living parts of this environment? What is the habitat where the fish live? Where does the energy for this ecosystem come from?

4. Food webs show us how energy in food is passed from one living thing to another. All living things need energy and nutrients to survive. They get energy through eating (consumers) like animals or by making their own food (producers) like plants.

5. Can you match the living thing with the food they eat? Living Thing Foods they like Carnivores eat meat Omnivores eat everything Herbivores eat plants Decomposers eat dead things

6. Symbiosis: a relationship between two living things Three Types of relationships Mutualism: both help each other. The ants protect aphids and farm them for their honeydew Commensalism: one is helped. The remoras eat bits of food the sharks drop. Parasitism: one is helped and the other is hurt. Ticks feed off living things but carry diseases.
