onmutualismparasitismMAIN IDEA: Competition and predation are two important ways in whichorganisms interact.Next to each situation described below, write whether it is an example ofinterspecific competition or intraspecific competition.1. Two squirrels race up a tree to reach a hidden pileof nuts.2. A hyena chases off a vulture to feast on an antelopecarcass.3. Different species of shrubs and grasses on the forestfloor compete for sunlight.4. Brown bears hunting for fish on a river’s edge fightover space.5. Male big horn sheep butt heads violently in competitionfor mates.6. Draw and label a sketch that represents an example of a predator-preyinteraction.
MAIN IDEA: Symbiosis is a close relationship between species.7. For each type of symbiotic relationship, complete the chart with details abouthow each organism is impacted using the terms “Benefits,” “Harmed,” or “Noimpact.” For each situation, assume that Organism A initiates the relationship.Symbiotic RelationshipOrganism AOrganism Bmutualismcommensalismsparasitism8. How is parasitism similar to and different from predation?9. What is the difference between endoparasites and ectoparasites?10. The term symbiosis comes from a Greek term which means “living together.”How does this word origin help to explain the definition of symbiosis?11. Use your knowledge of the word mutual to write a definition for mutualism.12. The word commensalism comes from the Latin mensa, meaning “table,” andcom-, meaning “with.” If I come to your table to eat your food, I benefit butyou don’t. Draw a sketch to show this meaning to help you remember it.
