8TH GRADE INTEGRATED SCIENCE UNIT: Bioenergy Unit NAME________________________ PERIOD______ INTERACTIONS AND RELATIONSLHIPS AMONG LIVING THINGS (THIS ASSIGMENT MUST BE SUBMITTED TO YOUR TEACHER BEFORE YOU CAN TAKE MAKE-UP QUIZ) Standard II: Students will understand that energy from sunlight is changed to chemical energy in plants, transfers between living organisms, and that changing the environment may alter the amount of energy provided to living organisms. Objective 2: Generalize the dependent relationships between organisms. Lesson Objective: I can model relationships where one organism gains, loses or stays the same in the following relationships: producer/consumer, predator/prey, mutualism, parasitism Vocabulary: predator, prey, predation, consumer, producer, competition, mutualism parasitism, host, parasite, commensalism, symbiosis Part I: Background on Relationships Among Living Things Predation Producers/Consumers Producers are autotrophs (make own food) and consumers. are heterotrophs that eat produces or other consumers . Symbiosis Symbiosis is a close relationships between two organisms from different species that live nearby or on each other. There are three symbiotic relationships: mutualism, commensalism, and parasitism Mutualism Example of Mutualism Mutualism is the relationship between two different organisms in which both organisms benefit from the association. Hummingbird gets nectar and flower gets pollinated. Example of Commensalism Predation is the relationship between two different organisms in which one organism (predator) hunts and kills the other organism (prey) for food. A lion will hunt and kill zebra for food. Competition Competition is the interaction among organisms for resources, such as food, living space, or mating. Carnivores like the lions and hyenas compete for the same (zebra) food and in the same territory Parasitism Parasitism is the relationship between two different organisms in which one benefits from the relationship (parasite) and the other (host) is harmed. A flea (parasite) bites the dog (host) and gets food. Hummingbird and Flower Commensalism Commensalism is the relationship between two different organisms where one organism benefits and the other neither benefits nor is harmed. Cattle egrets eat the insects stirred up by the moving livestock eating the vegetation. . Example of Parasitism Page 2 Interactions and Relationships Among Living Things Part II: YouTube Video Watch the YouTube Video “Interactions of Living Things In An Ecosystem” by following the directions: Google “YouTube” and click on the YouTube link.

There are three different types of relationships between organisms: _____________________ , _____________________ interactions, and ______________________.relationships. 2. _______________ is any relationship between two different species that live closely together. 3. There are three different types of symbiotic relationships: _______________________, _____________________, and _______________________. 4. The symbiotic relationship where both species benefit is called ________________________. Both organisms get something out of it. 5. Example of mutualism is the bees and flowers. Bees ______________ by getting food from the flower and the flowers _________________ from the bees helping the flowers reproduce using the pollen. 6. The definition of ____________________ is the symbiotic relationship between organisms where one benefits and the other is ________________. 7. Example of commensalism s the shark and the remora. The remora ______________ by getting a free ride and food. The shark really is unaffected by the remora. 8. __________________ is the symbiotic relationship in which one organism benefits and the other is harmed. 9. Example of ____________________ is zombie fungus and ants. In this relationship the zombie fungus _________________ by getting inside the ants where it reproduces, kills the an, and uses it for food. 10. ______________________ occurs when two or more organisms seek the same ___________________ at the same time 11. Some of the resources include _________________ and living ________________. 12. Example of competition is two tigers who want to living in the same living _______________ to get the same _______________. The animals will fight it out for _________________. The _________________ animal gets the territory. 13. A __________________ is an organism that captures and eats another organism. 14. A _______________ is an organism that is captured and eaten by another organism. 15. An example of predator-prey is a gazelle running away from a cheetah. The cheetah is the _______________ because it is giving chase. The gazelle is the ____________.
