variable. (2) Refer to your graph and explain what it shows you. Look for patterns as well. How did one population change in response to the other? (3) Error analysis. Write out at least three ways your data may not be completely accurate. Include a specific solution to prevent this problem in the future for each error. __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ Conclusion : The following topics need to be addressed: (1) Does the data support your hypothesis or not? (2) Real world application. Connect what you learned in this lab simulation about predation to how this relates to predation in a real community. Also include how competition can be related to predation, based on what you observed during this lab. __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________ __________________________________________________________________________________________

Ecology Unit © It’s Not Rocket Science 2016 47 Practice: Interactions of Organisms Read each scenario below and identify the type of relaionship(s) being described. If it is symbiotic, specifically label if it is mutualism, parasitism, or commensalism. If it is competitive, include if it is interspecific or intaspecific. Some may have more than one. 1. Termites feed on dead plant material and cellulose, both of which they find in wood. Termites are able to eat and digest wood because of the bacteria and protists that make their home in the termites’ intestines. 2. Moles create burrows underground – much to the frustration of many homeowners. Fortunately for the homeowners, rat snakes can inhabit their yards and eat the moles as a food source. 3. Many types of mushrooms are no harm at all to plants, but some types actually grow on trees and suck the nutrients out of the tree slowly, until it dies. 4. Mites often have the reputation of being harmful pests. However, mites and the carrion beetle have a different relationship. The carrion beetle transports the mites to different food sources, while the mites eat the maggots of flies that fight with beetle larvae for food. 5. If you look carefully at this picture of livestock, you will see small white birds interspersed around them. These birds are known as cattle egret. They do nothing to the cattle, but like to be near them because as the cattle move through the grasses and eat, they rustle up insects that the cattle egret can then easily eat. 6. Sea anemones do not actively seek out their food. They are considered “opportunistic” feeders because they simply take advantage and eat whatever passes by them that they can reach with their tentacles. Because of this, they do not like to inhabit the same areas as other sea anemones, and will often fight for space. 7. Bees and flowers have coevolved due to their benefits for one another. Bees assist flowers in pollination, while the flowers provide food for the bees. 8. Spider crabs have poor eyesight and are known as “lethargic scavengers.” They lazily move through more shallow parts of the ocean searching for food. Because of this, they are very exposed to their predators. Algae grow on the backs of spider crabs, which gives them some camouflage, and the algae has a home. 9. Cheetahs and lions live in the same regions and eat the same food sources, such as gazelles and small wildebeests. Because of this, when food is limited, they often have to fight to survive. 10. Spiders use tree limbs to support their webs, which don’t affect the tree.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
