One common system for computing a grade point average (gpa) assigns 4 points to an a, 3 points to a c, 1 point to a d, and 0 points to an f. what is the gpa of a student who gets an a in a 3 credit course, a b in each of two 2 credit courses, and a d in a 2 credit course?

Afood web shows who eats who in any given habitat. every living thing, from one-celled algae to giant blue whales, needs food to survive. each food web is a possible pathway that energy and matter can follow through the habitat. a food web begins with producers: organisms that convert sunlight into usable chemical energy. the food web is completed by the decomposers who turn organic wastes, such as decaying plants, into inorganic materials, such as nutrient-rich soil. decomposers complete the cycle of life, returning nutrients to the soil or oceans for use by producers. in this food web, identify the decomposer.
