This is an assignment for a short report on biological interactions. Students are to find two examples of each type of interaction.
Biological Interactions Research Report You are to write a report based on the five different types of species interactions. Competition Each species affects each other negatively; Trying to gain the same (inter- and intra-) resources. Include examples of both interspecific (different species) and intraspecific (same species). Parasitism One species benefits by living off another. The other species is harmed or weakened. Predation One species actively hunts and kills the other species for food. Commensalism One species benefits from the relationship, while the other is unaffected. Mutualism Both species benefit from the relationship. Coevolution The ultimate relationship; Two organisms that have evolved together. No Relationship The species live in the same ecosystem, but have no direct interactions. For each interaction listed, research two different examples of animals, plants, bacteria, or fungi that have these relationships. Each interaction should have its own paragraph in your report. Include the following information: 1. A definition of what defines this type of relationship, in your own words. 2. Identify the common and scientific name of each organism for your examples. 3. Explain the relationship the two organisms have; how each interacts with the other. 4. Include a citation at the end of the paragraph showing where you got your information. Here are some examples (you can’t use these in your report) - Clownfish / Sea Anemone (Mutualism) - Deer / Wolves (Predation) - Fleas / Dogs (Parasitism) - Sharks / Remoras (Commensalism) - Male lions (Intraspecific competition) - Wildflowers (Interspecific competition) Your report will be graded on the following: 2pts for correctly identifying the relationship (x7) _________ 2pts for fully explaining the relationship (x7) _________ 1pt for identifying each organism (x7) _________ 2pts for common and scientific names (x7) ________ 1pt for citing your sources (x7) _________ 4pts total for spelling and grammar __________ Total: ________ out of 60 Educational Worksheet by James Dauray | http://www.aurumscience.com 1
