Coral Reef WebQuest 50 pointsIntroduction: When we look at the living world, we have learned that it can be both complex and diverse. All the organisms found in a location are called a community. The community along with the non-living environment, (abiotic), in which they live is called an ecosystem. The energy of a system flows through the biotic environment through pathways of photosynthesis, feeding, and decomposition. The main chemical elements that flow through an ecosystem are Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorous. Energy flows through an ecosystem through various trophic levels or feeding levels??. An autotroph can synthesize its own food (organic materials) and is referred to as a primary producer. A heterotrophic organism must obtain their energy by consuming molecules synthesized by primary producers, at some level. Consumers exist at different levels including primary, secondary, and decomposers. The energy passed along in food consists of steps and much of it is lost as heat in the process. Processes such as photosynthesis and respiration in organisms lead to the complex interplay between members of an ecosystem, particularly related to feeding. Ecosystems can change over time in response to selective pressures but also in response to natural disturbances and disturbances caused by humans.Coral reefs are among the most productive and biologically diverse ecosystems on Earth. They supply vast numbers of people with goods and services such as seafood, recreational possibilities, coastal protection as well as aesthetic and cultural benefits. Estimates of coral reef cover range from approximately 0.1-0.5% of the ocean floor. Nevertheless, almost a third of the worlds marine fish species are found on coral reefs and the catch from reef areas constitutes around 10% of the fish consumed by humans. More than 100 countries have coastlines with coral reefs. In those countries at least, tens of millions of people depend on coral reefs for part of their livelihood or for part oftheir protein intake. Coral reefs are now affected by deforestation, intensive agriculture, urbanization, and consequent increases of nutrient and sediment loads as well as other kinds of pollution. Other human-associated factors that degrade coral reefs are overharvesting of reef organisms, destructive fishing methods, uncontrolled tourism, new diseases, and possibly global climate change.WebQuest Project:You will use the internet and other resources to research answers to questions related to a coral reef ecosystem. You will discover how reefs are established and explore the many organisms that make up the reef. You will also learn how humans and natural occurrences affect these delicate reef systems. This assignment will be submitted through Turnitin to check for plagiarism. Do not just simply copy and paste answers from weblinks. Read and paraphrase your answers. You have enough time to work on this assignment, so please form structured and complete sentences not yes or no.
