APES: Unit 2, Ecological Tolerance and Natural Disruptions to Ecosystems fully solved graded A+ 2023/2024

APES: Unit 2, Ecological Tolerance and Natural Disruptions to Ecosystems Natural Disruptions to Ecosystems - correct answer Changing Sea level due to the amount of glacial ice on Earth overtime, major environmental change/upheaval leading to habitat change, wildlife engaging in short term and long term migration for a variety of reasons (like natural disruption) Limiting Factor Principle - correct answer Too much or too little of any abiotic factor can limit or prevent growth of a population, even if all other factors are at or near the optimal range of tolerance. Abiotic Factors Affecting Populations - correct answer Salinity, sunlight, pH, nutrients, affect populations Tolerance Ranges - correct answer how much of a changing environment an organism can endure, based on the right level of an environmental factor being present in an ecosystem-- including optimal range, zone of physiologic stress, and the zone of intolerance Optimal Range - correct answer Population levels will be growing or at their peak Zone of physiologic stress - correct answer Levels of the factor are too high or too low. The population barely survives Zone of Intolerance - correct answer The population dies out. Geologic Processes Affecting Natural Selection - correct answer Tectonic plate movement, earthquakes, and volcanic eruptions Tectonic Plates Effect on Evolution and Location of Life - correct answer Locations of continents have shifted, species physically move, or adapt, or form new species through natural selection Climate Change Effect on Natural Selection - correct answer Ice Ages followed by warming temperatures Catastrophes- collision between earth and large asteroids, effect on natural selection - correct answer New species and extinctions Occur Periodic, Episodic, and Random and Effect - correct answer Wildfires, volcanic eruptions, and flooding-- cause wildlife to migrate and perhaps colonize new habitats, creates a change in the gene pool of populations, may result in speciation Speciation - correct answer Formation of a new species Percent of Change - correct answer final-initial/initial(100)
