11Ecology of Organisms Biotic vs. Abiotic Factors Biotic- living factors in the environmentEx. Plants, animalsAbiotic- non-living factors in the environmentEx. Climate, soil
12Ecology of Organisms Niche The specific role, or way of life of a species within its environmentWhat is the difference between a habitat and a niche?
13Exit Slip An ecosystem contains? Hunting season on deer increases the amount of grass/shrubs is an example of? (word for things depending on one another)A biotic factor in a pond is? Abiotic factor?
14Ecology of OrganismsConformers- do not regulate their internal conditionsRegulators- use energy to control some of their internal conditions
15Ecology of OrganismsTwo ways species can escape unfavorable conditions:1. Dormancy- state of reduced activity2. Migration- Move to a more favorable habitat
16Ecology of Organisms Generalists Specialists Organisms forage on a variety of food; feed on what is availableSpecialistsFocus on a specific food source
17Species Interactions Predation Predator- organism preys on other organismsPrey- animal taken by predator as foodExamples?
18Why are these animals fast or camouflage? Looking for students to say they are adaptations to catch prey, or avoid predators. They are adaptations to allow the to survive.
19Adaptations Predator Adaptations Adaptations that help predators acquire foodChemicalRattlesnack vs. RatCamouflageChameleonSpeedCheetah

21Mimicry What are the differences between the organisms? One snake is venomous, the other is not? What does it look the same?One butterfly tastes bad to predators so they don’t eat it, the other butterfly tastes good to predators. Why do they look the same?
22Prey Adaptations Mimicry BatesianHarmless species mimics a harmful speciesOctopus DefenseMullerianTwo or more species share similar warning colors or attributes
23Exit Slip What are two ways carbon enters the atmosphere? How is carbon removed from the atmosphere?Give one example of a predator adaptation and one prey adaptation.What is the difference in Mullerian and Batesian Mimicry?
49Greenhouse Effect1) Energy from the sun passes through the atmosphere and heats the earth’s surface2) Some of the heat radiates away from earth3) Some of the heat radiates into space4) Some heat is absorbed by gases and returned to earth
50Hydrosphere All of the water on earth Only 3 percent of surface water is freshwaterMost is in the form of glaciers
51Geosphere The earth’s rock interior Extends from the molten center to the crust
52Biosphere All parts of the earth where life exists
