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%
