Ozone naturally decomposes to oxygen via photodecomposition. 2 o3(g) ® 3 o2(g) ∆erxn = -284. 4 kj/mol, ea = 17. 7 kj/mol the temperature of the lower stratosphere is typically around –80oc in winter, while increases to around –60oc in the summer. How much faster is the photodecomposition of ozone in the summer compared to the winter?.

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.
