Lake Tahoe is one of America’s deepest‚ freshwater lakes. The iconic vacation spot keeps locals and tourists occupied with ski resorts and casinos. Although‚ there is more to the area than its breathtaking views. The Lake Tahoe Basin is home to many species that contribute to its ecology. Species interaction with biological communities and environment affect the ecosystem greatly because of species dependency of the environment and its resources. This makes it especially difficult with the Lake

Basic Ecology Terms: Ecology- the study of how organisms interact with their environment Organism- a living thing that gets food‚ water‚ shelter‚ and other things it needs to live‚ grow‚ and reproduce from its environment Habitat- environment that provides needed things Biotic Factors- the living part of a habitat Abiotic Factors- the non-living part of a habitat (soil‚ oxygen‚ water‚ sunlight‚ temperature) Species- a group of organisms that can mate with each other and produce offspring that

density-dependent and density-independent factors play a role? Chapter 41 1. What are the five main types of interspecific interactions discussed in the chapter? Describe each. 2. When interactions result in a negative outcome for one species (e.g. parasitism‚ predation‚ herbivory)‚ the species that is affected will typically have a response to prevent that negative outcome. Describe examples of how species respond to these effects. 3. How do invasive species affect the natural populations? 4. What
