Ecology Chapter 2 Welcome to Jeopardy All deserts are an example of ■ ■ ■ ■ A. Biome B. Biosphere C. Ecosystem D. Community Two blue jays fighting over one female is an example of ■ ■ ■ ■ A. Interspecific Competition B. Intraspecific Competition C. Symbiotic Relationship D. Mutualism Producers are also known as …. Bears are an example of ________. ■ ■ ■ ■ A. Omnivores B. Detrivores C. Carnivores D. Autotrophs The first step where abiotic factors are introduced … ■ ■ ■ ■ A. community B. ecosystem C. habitat D. biome In what type of activity would you most expect an ecologist to be involved? A. B. C. D. identifying and classifying various species of insects in an ecosystem locating fossils of distinct species of turtles in a geographical area observing the relationships that woodpeckers have with other species in their environment 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 Energy is released in the form of… How long are food chains? ■ ■ ■ ■ A. Four steps long B. Three steps long C. Varies with ecosystem D. Varies with day length. The following picture represents ■ ■ ■ ■ A. Population B. Community C. Ecosystem D. Organism If you were to add seaweed, coral reef, sunlight, and algae in the picture below, what would we be describing? ■ ■ ■ ■ A. Population B. Community C. Ecosystem D. Organism What do the arrows in the diagram represent? The following picture is an example of.. ■ ■ ■ ■ A. Community B. Biosphere C. Ecosystem D. Population The following is an example of what type of relationship? The species interaction most frequently represented in a food chain is ■ ■ ■ ■ A. Mutualism B. Commensalism C. Predation D. Symbiotic relationship How much of the energy is released when one species eats another? An example of ___________ can be observed between barnacles and whales. Barnacles are normally sessile, or non-moving sea creatures. They rely on currents to bring food past them in order to eat. However, some barnacles have attached themselves to the sides of various sea life, such as whales, in order to have a more advantageous position in life. These barnacles benefit by receiving transportation all over the ocean, which exposes them to more currents and feeding opportunities than they would normally experience. The whale neither benefits nor is harmed by the barnacles. Fill in the blank above Which of the following is listed from the least complex to the the most complex interactions? ■ ■ ■ ■ A. Population, Community, Biome, Ecosystem B. Community, Biome, Ecosystem, Community C. Ecosystem, Community, Biome, Biosphere D. Population, Community, Ecosystem, Biosphere Explain a type of INTRASPECIFIC relationship…. An ecological pyramid shows all of the following except: A. B. C. D. energy biomass abiotic factors number of organisms Which trophic level would you find the most organisms/biomass? Define Energy Energy cannot be created or destroyed. This follows…. In an energy pyramid with 4 trophic levels, how much energy would be at each level if the sun radiates 60,000,000 joules of energy on the producers? What is the organisms estimated population size given the information below? 23 15 29 10 22 N=AxC/R You want to estimate the frog population in Montville. You capture 43 frogs and tag them, then let them go. A month later you capture 31 frogs, 10 of them that are recaptured. How many frogs are in this population size? Why does a population follow a logistic growth trend? Name two types of organisms that experience exponential growth …
