This kettle lake formed 14,000 years ago when a glacier that covered the surrounding area melted. Initially devoid of animal life, overtime the lake was colonized by invertebrates and other animals. If you are a researcher, based on the background information, hypothesize how mutation, natural selection, genetic drift, and gene flow may have affected populations that colonized the lake.

no they are not always accurate because they can not give you a specific fortune reading they can not tell you exactly what’s gunna happen

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
