Ecology Study Guide Chapter 51 Animal behavior is anything to do with animals and they way they function and reproduce. Proximate cause is the immediate trigger for a behavior. For example, if a zebra is drinking at a water hole, and all of a sudden it hears another zebra nearby make an alarm call, it may stop drinking immediately and start running away instead. The proximate cause of the zebra running away would be the alarm call. But the ultimate cause, or real reason why the zebra is running is survival. It is running away because it wants to survive. The alarm call is not the source of danger, but the alarm call alerts the zebra that danger, such as a lion, may be nearby and the lion can threaten the zebra's chance to survive.

Chapter 4 Evolution and Biodiversity Summary 1. Life emerged on the earth through two phases of development: a chemical evolution of the organic molecules, biopolymers, and systems of chemical reactions to form the first cells and the biological evolution from single-celled prokaryotic bacteria to single-celled eukaryotic creatures, and then to multicellular organisms. 2. Evolution is the change in a population?s genetic makeup over time. Evolution forces adaptations to changes in environmental conditions in a population. The diversity of life on earth reflects the wide variety of adaptations necessary and suggests that environmental conditions have varied widely over the life of the earth.

Emits a potent toxin that quickly kills fish 2. Could have up to 24 life stages a. Carnivorous stage b. Free floating amoeba c. Protective casing and able to remain dormant 3. The discovery of Pfiesteria in North Carolina Rivers created panic among the areas recreation and fishing industries 4. Many investigators were very skeptical and even thought that Pfiesteria didn?t produce toxins at all 5. Pfiesteria shows that releasing waste material into a river can affect the environment in complex and unexpected ways 6. Also displays how controversial how environmental science can be

Some Services: Purification of air and water Mitigations of floods and droughts Detoxification and decomposition of waste products Generation and renewal of soil and soil fertility Pollination of crops and natural vegetation Control of the vast majority of potential agricultural pests Dispersal of seeds and translocation of nutrients Maintenance of biodiversity, from which humanity has derived key elements of its agricultural, medical and industrial enterprise Protection from the sun?s harmful rays Partial stabilization of climate Moderation of temperature extremes and the force of winds and water

Chapter 4: Biodiversity and Evolution 4-1 What is biodiversity and why is it important? Biodiversity is a Crucial Part of the Earth?s Natural Capital Biological Diversity (Biodiversity) is the variety of the earth?s species. The genes they contain, the ecosystem in which they live, and the ecosystem processes such as energy flow nutrient cycling that sustain all life. Genetic Diversity enables life on earth to adapt and survive dramatic environmental changes. Ecosystem diversity are storehouses of genetic and species diversity Functional diversity is the variety of processes such as matter cycling and energy flow taking place within ecosystems. 4-2 Where Do Species Come From? Biological Evolution by Natural Selection Explains How Life Changes Over Time

7.1 Succession Ecological succession is the directional change in the composition of species that occupy a given area through time: it involves initial colonization and establishment of pioneer plant species, followed by their replacement with other species until a relatively stable community is formed. Ecosystems are made up of all the interacting biotic (food availability, competition and predation)and abiotic (non-biological environment ? pH, temperature, rainfall and humidity)factors in a particular area within which there are a number of communities of organisms. Ecosystems constantly change, Succession is the term used to describe these changes, over time, in the species that occupy a particular area. A sere (seral stage) is the series of stages in succession.
