3–3 Cycles of Matter Slide 1 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter 3-3 Cycles of Matter How does matter move among the living and nonliving parts of an ecosystem? Slide 2 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Sun Power Slide 3 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Recycling in the Biosphere Recycling in the Biosphere Energy and matter move through the biosphere very differently. Unlike the one-way flow of energy, matter is recycled within and between ecosystems. Biogeochemical Cycles Slide 4 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Nutrient Cycles Nutrient Cycles All the chemical substances that an organism needs to sustain life are its nutrients. Every living organism needs nutrients to build tissues and carry out essential life functions. Slide 5 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Nutrient Cycles The Carbon Cycle Carbon is a key ingredient of living tissue. Biological processes, such as photosynthesis, respiration, and decomposition, take up and release carbon and oxygen.

What are the non-natural ones? • http://www.nodvin.net/snhu/SCI219/demo s/Chapter_3/Chapter_03/Present/animatio ns/51_1_3_1.html Slide 8 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Nutrient Cycles The Nitrogen Cycle All organisms require nitrogen to make proteins. Only certain types of bacteria can use nitrogen directly. Such bacteria live in the soil and on the roots of plants called legumes. -Nitrogen fixation Slide 9 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Nutrient Cycles N2 in Atmosphere Synthetic fertilizer manufacturer Uptake by producers Uptake by producers NO3 and NO2 NH3 Slide 10 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Slide 11 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Nitrogen Cycle Slide 12 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Bacterial nodules Slide 13 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Nutrient Cycles The Phosphorus Cycle Phosphorus is essential to organisms because it helps form important molecules like DNA and RNA. Slide 14 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Organic phosphate moves through the food web and to the rest of the ecosystem.

Slide 16 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter The Water Cycle Water moves between the ocean, atmosphere, and land. Slide 17 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Nutrient Limitation Nutrient Limitation The primary productivity of an ecosystem is the rate at which organic matter is created by producers. - Nutrients limit primary productivity Limiting Nutrient – a nutrient that is in short supply in an ecosystem. Slide 18 of 33 Copyright Pearson Prentice Hall End Show 3–3 Cycles of Matter Nutrient Limitation Algal bloom: When a limiting nutrient is suddenly increased in an aquatic ecosystem, algae can rapidly grow and disrupt the equilibrium.
