Autotrophs The loss of water vapor from parts of plants is called…. What type of organism returns nutrients to an ecosystem? __________is the ultimate energy source driving the biogeochemical cycles. A food pyramid displays all the following EXCEPT A. amounts of energy B. Biomass C. Percent degration D. numbers of organisms In what type of activity would you most expect an ecologist to be involved? A. identifying and classifying various species of insects in an ecosystem B. locating fossils of distinct species of turtles in a geographical area C. observing the relationships that woodpeckers have with other species in their environment D. studying the internal organs of a seal to learn how it survives in its environment What is each step in a food chain called? A bird fluffs its feathers to trap warm air close to its body. The temperature of the air next to the bird’s skin is a(n) A. Abiotic Factor B. Biotic Factor C. Niche D. Homeostasis Factor Which type of organism exists at all trophic levels except the first trophic level? A. carnivores B. herbivores C. autotrophs D. heterotrophs In the energy pyramid shown below which level has the smallest number of organisms? What percentage of water vapor comes from transpiration? How long are food chains? A. Four steps long B. Three steps long C. Varies with ecosystem D. Varies with day length. What is denitrification? Which biogeochemical cycle involves evaporation, transpiration, precipitation and runoff? Which biogeochemical cycle(s) directly affect humans? The following picture represents A. Population B.

Organism Nitrogen molecules are released back into the atmosphere during what process? What factor(s) affect the water cycle? What do the arrows in the diagram represent? The following picture is an example of.. A. Community B. Biosphere C. Ecosystem D. Population Which process best describes nitrogen fixation? A. animals eat plants containing nitrogen and return it to the soil through urination B. bacteria take nitrogen from the air and convert it to a form usable by plants C. organisms die and are decomposed into ammonia in the soil D. plants take nitrogen from the air and store it in their roots The following is an example of what type of relationship? Some farmers use manure on their crop fields. How does this help the plants?

Please grab a piece of paper, and write your group’s names at the top. Discuss how many points you want to wager. The Question…. Compare and contrast nitrification and nitrogen fixation, and give me the end product from both.
