Alice Hu, Huda Tariq, Jessica Paine Biology 30-1 AP June 14th, 2019 Interspecific Competition and the Principle of Competitive Exclusion: The Douglas-Fir trail is a mosaic of different plant and animal life. In this picture, you can see the two different species of grass inhabiting the same region of soil; one with thinner blades and one with thicker blades. The thick bladed grass is centipede grass, while the thin bladed grass is ryegrass. This is an example of interspecific competition as these different species of grass compete for limited resources like sunlight, water and nutrients from the earth while inhabiting the same niche and living area. This is also a possible example of the principle of competitive exclusion which states that if two species attempt to occupy the same niche, one species will out-compete the other. In this case, the centipede grass was more often spotted than the ryegrass, which shows evidence of the centipede grass out competing the ryegrass.

    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.
