Unit 8 Essay Prompts
Sorry guys that this is so late... I just had to go to sleep. Anyways, this guide is to help inspire you about the essay prompts and provide a little info, you'll have to do additional research on your own. Also, I'll try to bring up better examples.
1) Explain and illustrate with one specific example of each of the following concepts: a) competitive exclusion (Gause's principle) 1. definition = states that when two species with the same resource needs are put into the same environment, the species that is able to use its resources better and more efficiently will cause the other species to eventually become extinct. 2. example = the experiment involving two species of protozoans (pg. 1115) …show more content…
Usually, R-selected populations grow first since they have higher fecundity. Later, K-selected species will become established and really settle down... which is how climax forms. c) species diversity and interaction = causes competition for the available resources d) inhibition and facilitation e) page 1124
6) Describe the biogeochemical cycles of carbon and nitrogen. Trace these elements from the point of their release from a decaying animal to their incorporation into a living animal. a) check out chap 54 study guide for both cycles b) carbon cycle = cellular respiration, photosynthesis c) Nitrogen cycle = nitrification, denitrification, nitrogen fixation, ammonification, atmospheric deposition d) page 1140 – 41
7) Using an example for each, discuss the following ecological concepts: a) Succession 1. um... look at prompt 5 b) Energy flow between trophic levels 1. look at chap 54 study guide.... 2. primary productivity and secondary productvity 3. energy transfer only about 10%
