Name ____________________________________________ Period _____ SPECIES INTERACTIONS Part A: Match the following relationships to the examples below (relationships may be used multiple times; some questions have multiple relationships): A. Commensalism B. Parasitism C. Competition D. Predation E. Mutualism ____ 1. In an ecosystem, a hawk and a snake both eat mice. ____ 2. My dog, Sputnik, has a wood tick on him. Boo. ____ 3. A cardinal eats berries, but a bear chases her away to feast. ____ 4. Moss grows on the bark of a tree. ____ 5. A lion stalks a gazelle. ____ 6. A lichen is actually composed of a fungus and an alga. The fungus keeps the algae from drying out and the algae gives sugars to the fungus. Really? Yes! ____ 7. During mating season, two male kangaroo are fighting for a female. ____ 8. Indian Pipe is a non-green plant that steals nutrients from tree roots instead of photosynthesizing. Oh yes it does. ____ 9. Fig trees are pollinated by tiny wasps; the wasps mate and lay eggs in the fig fruits. ____ 10. Two barn spiders build their webs in adjacent windows. ____ 11. A cocklebur seed catches a ride on the fur of a cat. ____ 12. A whooping crane eats a frog in one gulp. Part B: Now go back and highlight/underline the producers one color, herbivores in a second color, carnivores in a third color and decomposers in a fourth color. Include a key.
