PPT-Nutrient cycles and global ecosystems

Getting started Youll need a notepad on which to make notes as you go along or you could make notes paste images etc on your device You can view these slides as a slideshow for any animations and to follow links. Understanding Nutrient Budgeting • What are Nutrient Budgets? – Simply a method of accounting for nutrients that come into and leave your farm Nutrient Budgeting , Brief History Deve Lake Victoria. Incredible diversity of cichlid fishes.. More than half of the 500 species now endangered.. Nile perch. Increased phytoplankton. Cyanobacteria. Lake Victoria. Algal bloom causes and increasing rate of decomposition as algae die off.. Topic 11 – Nutrient Dynamics. Nutrient Cycles and Budgets. Nutrient Transport , Spiraling and Uptake. Controls on Nutrient Dynamics. Measuring nutrient uptake. General definitions. Nutrient Cycle . William H. Schlesinger. Millbrook, New York. 1. Some basic stoichiometry for life―in biomass. . . First articulated by Liebig (1840). and later advanced by Redfield (1958), Reiners (1986), . Sterner and . keep . producing food in a way that not only conserves, but renews our natural resources, while it improves nutrition and health outcome for the world’s increasing population” . (McCann, 2017).. Aquatic ecosystems are primarily determined by the ecosystem’s . salinity. . Salinity refers to the dissolved salt content of the water.. Aquatic ecosystems are divided into freshwater and marine ecosystems.. Some of the chemical building blocks of life, called . macronutrients. , are required by organisms in large quantities. Water . –. Carbon. Hydrogen . –. Oxygen. Nitrogen . –. Phosphorous. Ocean Zones & Ecosystems. Freshwater Zones & Ecosystems. Related Ecology. Benthic Division. 6 Areas. . 1. Supralittoral zone. (supra= upper, litus=shore). . Water splashes but does not stay submerged. CLIMATE FROM A GEOLOGIC PERSPECTIVE 1 GLOBAL WARMING/COOLING CYCLES FROM A GEOLOGIC PERSPECTIVE (meaning a very long time horizon) By Rocky Romero Rev 3 CLIMATE FROM A GEOLOGIC PERSPECTIVE 2 I’ve structured the explanation of Climate Change in three parts… Getting started. With this GEO resource you will be learning about the location and biodiversity of . coral reefs. , their value to us and the environment and threats affecting global reefs today. We will also investigate the response to such threats in term of management.. Energy vs. Matter. Energy flows throughout an ecosystem in ONE . direction. from the sun to autotrophs to heterotrophs. Matter is recycled. WHY? . Biogeochemical Cycles. “Matter can cycle through ecosystems because organisms don’t USE it, they TRANSFORM it.”. Unit 3: Resource Sustainability. Nutrient cycles. Nutrients – chemical . substance that an organism must obtain from its environment to sustain life and undergo life processes. . These nutrients are recycled so they can be reused! . Including:. Biological use of each nutrient. Processes in the ecosystem that effect its availability. A diagram of the cycle. Nitrogen- 2 pages. Carbon- 2 pages. Phosphorus- 1 page. Magnesium- 1 page. AICE Marine. Detritus:. What is it?. How does it fit in to a food web/chain?. Who/what consumes it?. Detritus:. What is it? . Dead, decaying organic matter . How does it fit into a food web/chain? .
