FLOW OF ENERGY THROUGH THE ECOSYSTEM BY: JULIAN NEME JARED DALLING ALLAN VARELA LIFE DEPENDS ON THE SUN • PHOTOSYNTHESIS: • Is a process used by plants and other organisms to use light energy usually the sun ‚ to make sugar molecules. • The result of photosynthesis is sugar which is called CARBOHYDRATES PRODUCERS‚ CONSUMERS‚ DECOMPOSERS • Producers: is an organism that makes its own food. • Consumers: is organisms that get their energy by eating other organisms. • Decomposers: there organisms

Communities and Ecosystems 37.1 Multiple Species Interact in Communities ~Communities are composed of coexisting populations of multiple species ~An ecosystem consists of a biotic community plus its abiotic environment ~Each species in a community has a place where it normally lives and a set of resources necessary for its life activities ~Ecologists describe the diversity of a community by measuring species richness and the relative abundance of each species. * Populations interact in many

LIGHT IN PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place

CHAPTER 7 STUDY GUIDE AN OVERVIEW OF PHOTOSYNTHESIS Autotrophs are plants that can feed themselves by making their own food. Photo-autotrophs are organisms that produce organic molecules from inorganic molecules using the energy of light. Producers are when plants make their own organic molecules. A redox reaction is oxidation and reduction. Photosynthesis takes water and carbon dioxide to make glucose and oxygen. Cellular respiration takes glucose and oxygen to make water and carbon dioxide.

Biology 11 December 12 ‚ 2012 Photosynthesis and global warming Introduction: Photosynthesis can reduce the amount of carbon dioxide in the air. It represents a sink for carbon dioxide in the environment. Reducing forests and other vegetation can produce a net increase in atmospheric carbon dioxide. Therefore‚ more photosynthesis might act to reduce global warming. On the other hand‚ this is a more complicated title than it appears at first. Photosynthesis: The process in green plants

Observing Ecosystems Ecosystems-The sums of all the organisms living within its boundaries and all the abiotic factors with which they interact. Chemical Elements such as carbon and Nitrogen are cycled among abiotic and biotic components of the ecosystem. Photosynthetic organisms assimilate these elements in inorganic form from the air‚ soil‚ and water and incorporate them into their biomass‚ some of which is consumed by animals. Both energy and matter are transformed in ecosystems throught

Why Recycle Paper? “I recycle because I feel like I’m being a good person and contributing to society‚” says Amanda Enclave of suburban Los Angeles‚ California. About 30% of people in America recycle regularly and there are questions to ask about it. Why recycle? What are we gaining by recycling? Does recycling actually help the environment? Hopefully this paper will show recycling for what it is: useless. John Tierney writes in the New York Times‚ …recycling programs aren’t good for posterity

is called photosynthesis. This process is used by plants and other organisms for synthesis of lipids and amino acids or can be metabolized during cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon

interrelationships among the organisms and the environment‚ and we are closer to an actual understanding of this ecosystem. Here we will be studying the biotic and abiotic components of two major freshwater ecosystems we’ve visited- the Ampang lake and the Gombak river. Biotic factors consist of the living things that shape an ecosystem (Library.thinkquest.org). After examining the lake and river ecosystems‚ we only found two similar biotic components‚ which are the stonefly larvae (Plecoptera) and fish.
