Which of the following is a strategy associated with conservation biology?  Designating a nature reserve to protect an endangered wildcat species.  Re-establishing a native species of pine t... ree in an area used previously by loggers.  Exploring the interdependence of species within ecosystems on a global scale.  Monitoring and evaluating groundwater quality in a formerly contaminated site. CONCEPT Conservation Biology & Restoration Ecology 2 Which of the following is a non-renewable resource?  Wind  Wood  Biomass  Petroleum CONCEPT Natural Resources 3 Which statement is NOT true about energy and trophic levels within a food web?  Most of the energy between trophic levels is lost in the form of metabolic heat.  Secondary production introduces only 1% of new energy to the food chain.  The rate at which energy accumulates in plants depends on temperature, sun and water.  About 90% of the energy available at one trophic level does not transfer to the next. CONCEPT Food Chains and Food Webs 4 Which of the following is NOT an example of overexploitation?  Little more than one thousand bison existed in North America by the 1880s.  Fur processing in Canada is carefully regulated to protect both the animals and the environment.  90 species of Asian turtles are collected in Singapore and Cambodia for Chinese restaurants.  Slow-growing medicinal plants are harvested before they have a chance to reproduce. CONCEPT Overexploitation 5 Population ecologists study which of the following characteristics?  Temperature regulation, nutrition and metabolism of organisms.  Number, density, age, and sex of organisms.  Atmosphere, rocks, water and living organisms.  Composition, distribution and interaction of species in a given area.
