- On one acre of land, annelids can process about ____ pounds of soil a year. O 16 O 2,000 O 16,000 O 1,000,000Iguana Decline In 1987, Martin Wikelski began a long-term study of marine iguanas in the Galpagos Islands. He marked iguanas on two islandsGenovesa and Santa Feand collected data on how their body size, survival, and reproductive rates varied over time. He found that because iguanas eat algae and have no predators, deaths usually result from food shortages, disease, or old age. In January 2001, an oil tanker ran aground and leaked a small amount of oil into the waters near Santa Fe. FIGURE 44.3 shows the number of marked iguanas that Wikelski and his team counted in their study populations just before the spill and about a year later. FIGURE 44.3 Shifting numbers of marked marine iguanas on two Galpagos islands. An oil spill occurred near Santa Fe just after the January 2001 census (orange bars). A second census was carried out in December 2001 (green bars). Which island had more marked iguanas at the time of the first census?________ is lifes primary source of energy. a. Food b. Water c. Sunlight d. ATP

To keep horseshoe crab populations stable, blood is extracted from captured animals, which are then returned to the wild. Concerns about the survival of animals after bleeding led researchers to do an experiment. They compared survival of animals captured and maintained in a tank with that of animals captured, bled, and kept in a similar tank. FIGURE 24.28 shows the results. FIGURE 24.28 Mortality of young male horseshoe crabs kept in tanks during the 2 weeks after their capture. Half the animals were bled on the day of their capture. Control animals were handled, but not bled. This procedure was repeated 8 times with different sets of horseshoe crabs. Based on these results, would you conclude that bleeding harms horseshoe crabs more than capture alone does?Sustainable Use of Horseshoe Crabs Horseshoe crab blood clots immediately upon exposure to bacterial toxins, so it can be used to test injectable drugs for the presence of dangerous bacteria.

- Testing Biological Control Biological control agents are used to battle red imported fire ants. Researchers have enlisted the help of Thelohania solenopsae, a natural enemy of the ants. This microsporidian (Section 23.4) is a parasite that infects ants and shrinks the ovaries of the colony's egg-producing female (the queen). As a result, a colony dwindles in numbers. Are these biological controls useful against imported fire ants? To find out, USDA scientists treated infested areas with either traditional pesticides or pesticides plus biological controls (both flies and the parasite). The scientists left some plots untreated as controls. FIGURE 45.16 shows the results. FIGURE 45.16 A comparison of two methods of controlling red imported fire ants. The graph shows the numbers of red imported fire ants over a 28-month period. Orange triangles represent untreated control plots. Green circles are plots treated with pesticides alone. Black squares are plots treated with pesticide and biological control agents (parasitoid flies and a microsporidian parasite). How did population size in the control plots change during the first four months of the study?T-Sclence-Gr5-T8C-PBT (2020-2021) Questlon: 1-9 Monarch butterflies travel long distances each winter.

An example(s) of environmental conditions is/are: temperature nutrients sunlight all of these. Part B)DR TJ freaks out because she doesn’t hear any cicadas singing in January.
