Nthe textbooks for this course, cain et al. define ecology as"the scientific study of interactions between organisms and their environment"while begon et al. have a more detailed definition: "the scientific study of the distribution, abundance, and interactions among organisms, and the relationships between organisms and the transformation and flux of energy and matter." these definitions say the same thing as long as two of the following four statements are correcti. in the cain et al. definitionthe environment includes only the abiotic component ii. in the cain et al. definitionthe environment includes both abiotic and biotic components iii. in the cain et al. definitionthe transformation of energy and matter is carried out by organismsiv. in the cain et al. definitionthe transformation of energy and matter is independent of the activity of organismsa. i and iii are correct b. i and iv are correct c. ii and iii are correct d. ii and iv are correct

Sara goes on a slingshot ride in an amusement park. she is strapped into a spherical ball that has a radius 3*10^2 of centimeters. what is the volume of air in the spherical ball? use this formula: volume of a sphere=4/3pi,r^3 , where r is the sphere’s radius.

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
