PPT-What are ocean ecosystems?

Unit Standards 5L4A1 Analyze and interpret data to summarize the abiotic factors including quantity of light and water range of temperature salinity and soil composition of different terrestrial ecosystems and aquatic ecosystems . Miller chapters 3 & 4, 18. th. Ed.. Day 1. Goals. Students complete virtual owl pellet lab. Students can explain owls’ role in a food web. Students can define. Producer, consumer, decomposer. Students can draw: food web, food chain. Ocean Acidification: . How does changing ocean chemistry affect ocean ecosystems?. Jim Barry, Monterey Bay Aquarium Research Institute. Benthic Respiration Chamber System. Perturbation experiments in the deep-sea. - Jacques Ives Cousteau. 2. New Orleans is nested between the mouth of the Mississippi River and the brackish estuary of Lake Pontchartrain.. 3. A series of floodwalls, or levees, protects the city from ocean surges from large storms.. CHAPTER. Too Much of a Good Thing?. Elephant populations in southern Africa declined sharply due to hunting but have made overwhelming comebacks within nature reserves and parks.. Some worry that elephant overpopulation is causing a decline in local biodiversity and damage to farms and infrastructure.. 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.. Warm Up & Spiral . November 4. How are surface currents created?. How are deep ocean currents created? . What are 2 factors that affect the density of water?. What is upwelling? . Objectioves. : 8.E.1.1/1.2. 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. Section 3: . Aquatic Ecosystems. K. What I Know. W. What I Want to Find Out. L. What I Learned. Essential Questions. What are the major abiotic factors that determine the aquatic ecosystems?. What are transitional aquatic ecosystems and why are they important?. Why Should We Care? The deep sea , accounts for 99 % of the volume of the planet . It is comprised of many different ecosystems that provide key provisioning , supporting , regulating , and cultural s What is ecology?. It is the science that studies how . organisms. relate to each other and their . environment. .. Considers both . biotic. (living) and . abiotic. (nonliving) aspects.. Examples of abiotic factors: . Summary. This lesson utilizes the example of healthy estuaries to demonstrate tools scientists use to measure ecosystem health. Students will learn the definition and function of an estuary, an essential coastal ocean ecosystem. Students will then learn methods to measure parameters of large areas using quadrats and subsets. . Key Message #1. 9. Ch. 9 | Oceans and Marine Resources. The Nation’s valuable ocean ecosystems are being disrupted by increasing global temperatures through the loss of iconic and highly valued habitats and changes in species composition and food web structure. Ecosystem disruption will intensify as ocean warming, acidification, deoxygenation, and other aspects of climate change increase. In the absence of significant reductions in carbon emissions, transformative impacts on ocean ecosystems cannot be avoided.. TERRESTRIAL ECOSYSTEMS. AQUATIC ECOSYSTEMS. Ms. Catherine T. . Añano. (Fulltime Lecturer). Terrestrial ecosystems. A . terrestrial ecosystem is an ecosystem found only on landforms. . . Six . primary terrestrial ecosystems . Biomagnification. is the process by which matter becomes concentrated in living things in a food chain.. Moving up the Food Chain . DDT provides one example of the effects of . biomagnification. in an ecosystem. DDT is a chemical that was widely used to kill plant–eating insects. Some chemicals break down over time, but DDT does not. DDT collected in water and soil, was absorbed by living things, and moved up the food chain. The diagram shows how DDT became magnified in a wetland ecosystem. It entered through tiny organisms called zooplankton, which absorbed DDT from the water..
