Assignment 2: Discussionâ€”Species Interactions and You
Humans interact with various species every day without actually realizing it. In the field of ecology, these interactions can either be interspecific (between species) or intraspecific (within species). Interactions between humans are known as intraspecific (within species) interactions. For example, interactions between a human and a pet would be interspecific, whereas interactions between a human and another human would be intraspecific.
Research interspecific and intraspecific interactions using the module readings, the Argosy University online library resources, and the Internet.
This assignment has two parts. Complete both parts.
Complete the following:
- Track your interactions with other organismsâ€”between and within speciesâ€”for one day.
- Summarize your interactions throughout the day, using the terms from this moduleâ€™s readings. If required, review the moduleâ€™s readings again.
- At a minimum, identify ten interactions that you witnessed or participated in today. Among those interactions, you should be able to identify a predatory-prey relationship, a competitive relationship, and a mutualism. You could also identify parasitic relationships or commensalisms, if you choose. Although you can repeat interaction typesâ€”for instance, you can have multiple mutualismsâ€”the examples must differ. These are some examples:
- Did you have a predatory-prey relationship with a chicken today? That is, did you eat chicken for lunch?
- Did you have a competitive relationship with a coworker today? That is, were you competing for a raise?

Respond to the following:
- For every interaction you identified above, describe an interaction in nature that is similar to what you experienced or witnessed. For example, if you had a predatory-prey interaction with your meal, identify and describe an example of a predatory-prey interaction in nature. Or, if you had a competitive interaction with your coworker, identify and describe a competitive interaction in nature.
- Using the information you reviewed, explain why it is important to recognize these interactions.
Support your statements with appropriate examples and scholarly references.
Using the information that you compiled above, summarize your interactions for the day. Be sure to classify your interactions (parasitic, mutualism, etc.) and that you also determine if the interactions are considered intraspecific or interspecific.
Write your initial response in a minimum of 300â€“350 words. Apply APA standards to citation of sources.
By Saturday, August 23, 2014, post your response to the appropriate Discussion Area. Through Wednesday, August 27, 2014, review and comment on at least two peersâ€™ responses. In your response posting, address the following by employing the concepts covered in module readings and your research:
- Evaluate your fellow studentsâ€™ examples of interactions in nature. Are the categories accurately identified? Are the examples valid?
- What did you learn from the other studentsâ€™ entries and comparisons?
- Did you agree or disagree with studentsâ€™ explanation of the importance of recognizing these interactions?
Be sure to give reasons for your responses.
