AICE Marine Detritus What is it How does it fit in to a food webchain Whowhat consumes it Detritus What is it Dead decaying organic matter How does it fit into a food webchain . All . ecosystems. contain biotic and abiotic factors. Biotic. = living features. Abiotic. = non-living physical features. Relationship between biotic and abiotic factors is important to ecosystem health. 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. What are Ecosystems? . Groups of living things and the non-living environment in which they live.. The people that study ecosystems are called: . “ecologists.”. Let’s look at the living parts of the ecosystem:. 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. 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?. The Fiji Pearl Development Pla. n. was introduced June 7. th. 2017 at World Oceans day by the Fiji Government as one of 16 Voluntary commitments towards the implementation of Sustainable Goal 14.. 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: . 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.. Getting started. You’ll 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 slide-show for any animations and to follow links. Unit 3: Resource Sustainability. Nutrient cycles.
