A specialist fits into their environment tightly and there is no room for dealing with changes or for colonizing different habits; they are good at one specific thing. A generalist adapts to a wide range of environmental circumstances and food sources What is logistic growth? What limiting factors might lead to a given (K) carrying capacity? Logistic growth is the kind of population growth where the growth rate constantly decreases with the increasing number of individuals. When the population reaches it's max, the growth rate becomes zero. Factors such as food, water, and shelter, ass well as an excess in predator are limiting factors that might lead to a given carrying capacity. What is the energy pyramid? What is at the bottom? What is at the top? Where is the most energy and the least energy? Where is the most biomass and least biomass? Where is the highest number of individuals and lowest number? The energy pyramid is a graphical model of energy flow in a community. Producers are at the bottom while tertiary consumers are at the top. The most energy is at the bottom and the least energy is at the top. The most biomass is at the bottom and the least biomass is at the top. The different levels represent different groups or organism that might compose a food chain. What are the two key components of an animal's habitat? The two key components of an animal's habitat are food and shelter What is natural selection? Natural selection is the process that determines which individuals will pass on their genes to the next generation What are Biomes? Biomes are the type of habitat an animal lives in. e.g. forest, tundra, desert
