Chapter 54 - Community Ecology Homework 1. Explain the differences between competition‚ predation‚ parasitism‚ mutualism‚ and commensalism and give an example of each. Competition- (–/– interaction) occurs when species compete for a resource in short supply example when an invasive species moves in it cause competition. Large insects defend feeding sites on cottonwood leaves by kicking and shoving smaller aphids from better sites. Predation- (+/– interaction) refers to an interaction in which

Mutualism of a Bengal Tiger- A very powerful antibiotic‚ Bacilli is a type of bacteria belonging to the Enterobacteriaceae family. Specifically‚ Pantoea agglomerans of the bacilli family are helpful by producing a broad spectrum antibiotic andrimid. This kills many harmful bacteria that a tiger may ingest from its prey by blocking a critical step in fatty acid biosynthesis. This helps protect the tiger from such dangers like E. coli and samonella poisoning. Parasitism-An example of parasitism is

Did you know that literally anything can change or affect an ecosystem. All kinds of relationships affect an ecosystem. An Ecosystem is a biological community of interacting organisms and their physical environment. Changes to an ecosystem can literally change and affect everything in it. Things outside of an ecosystem can affect an ecosystem. Everything connects together. Living and nonliving changes to an ecosystem can change and affect everything in it.

top of the food chain back to the bottom. There are many symbiotic relationships in biological systems. There is mutualism which means both sides benefit from the interaction. An example of this is a bird picking an alligator’s teeth clean. The bird benefits with a meal and the alligator gets a healthy mouth. In this case‚ the alligator’s mouth also serves as resource. Commensalism is when one species benefits and the other sees no effect. An example of this is fish picking up the left overs after
