5. A class was doing field research using a capture-mark-recapture technique to estimate the population size of a population of monarch butterflies, which eat only milkweed as caterpillars. The size of the field was two hectares. Initially the class caught 150 butterflies, marked them carefully being sure not to harm them, and then released them. The next day the class came back to the same area and recaptured 100 of the monarchs. Twenty (20) of these were marked.What is the estimated size of the total population of the monarchs in this area? * A 75 B 750 C 1500 OD 3000 6. After random sampling, 500 piranha are captured, tagged ethically, and released back into an area of pooled water along the Amazon. A month later, 10 piranha of which 2 are tagged, are captured. Which option below illustrates the use of the Lincoln Index to estimate the total population of piranha in the pool? * A N=500 X 2/10 = 100 B N= 10 + 500/10 = 255 CN = 500 X 10/2 = 2500 O DN = 12 + 500/2 = 256 7. Why is biodiversity important to maintaining the health of ecosystems? A High biodiversity allows animals to permanently feed on one type of plant O B High biodiversity helps communities adapt to ecological change O C High biodiversity reduces the number of insects in the environment O D High biodiversity provides more food sources for the top predators 8. A biodiversity “hotspot” is: * Cara Cera Mourn of Mountains of Castomia Madrear Pey-Oak Fonsac Woodlands E Southwest Province Mediterranean Jabon Hay China Canton Basin Anton Inards Western Phades Galindo Meserica Slank Bumal Polynes Cerrado Hom of Micronesia Times Polynesia Guinean Forests Choco Alta Micronesia Sundaard E Magda of West Alca Madagason Waga Selain the Tropical Andes Indian Ocean Art Succident lalands Chilean Caledonia Forest Karoo Coastal Forests of Winter Rant Estem Amca Southwest Australia Vaidi Cape Florist Maputaland Forests Region New Zealand Pondoland Albany Esse Alomontane A.
