PPT-Ecosystems & Organisms

A place in the natural environment where living and nonliving items function in the same habitat What is the primary ecosystem that Tucson host Desert but if we were to travel up the Santa Catalina Mountains we would be traveling into different ecosystems at different elevations. Section 1.2. What are ecosystems?. Part of a biome that contains abiotic components (oxygen, water, nutrients, light and soil) that support biotic components (plants, animals and micro-organisms.. Can be small (a rotting log) or large (Forest or grasslands). There are two main categories of freshwater ecosystems. What is the main . difference between. these two ecosystems? . Standing water . v. . flowing-water ecosystems. Standing water—staying still, not moving. The continued survival of living organisms including humans depend on sustainable communities. . Understandings:. Species are groups of organisms that can potentially interbreed to produce fertile offspring.. Chapter 3 (Miller and . Spoolman. , 2010). Core Case Study: Tropical Rain Forests Are Disappearing. Cover about 2% of the earth’s land surface. Contain about 50% of the world’s known plant and animal species. Brooke Ard. 5. th. Grade Math/Science. Griggs Road Elementary. Aquatic Ecosystems. Water-based . ecosystems may be fresh water (lakes and ponds) or saltwater (oceans, . estuaries and . saltwater marshes).. 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.. 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:. 8/19/2013. EQ: How do organisms interact with their environment?. Chapter 2.1. Ecology.  Study of interactions between organisms and their surroundings. Section 3-1. Figure 3-2 Ecological Levels of Organization. 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. LO: . I can define and differentiate biotic and abiotic factors in an ecosystem . (5.L.4A.1). . EQ: . How do biotic and abiotic factors interact with each other in an ecosystem?. Ecosystem. Ecosystem. 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: . Decomposer. Autotrophs. Abiotic factor. Heterotrophs. Population. Biotic . factor. Microhabitat. Ecosystem. Producers. Habitat. Niche. Environment. Consumers. Community. Trophic level. Detritivore. Ecosystem. 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. . Unit Standards. 5.L.4A.1 . 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. .
