1. What is a biogeochemical cycle? A. A biogeochemical cycle is a pathway for chemicals necessary for life to move through the environment. 2. Fill in the blanks: Matter cannot be created or destroyed. Water‚ carbon‚ nitrogen‚ and oxygen must be recycled somehow in the environment‚ which also ensures that we do not use up or lose these essential materials. 3. Fill in the blanks: *Nitrogen is circulated in a biogeochemical cycle and is a necessary element in the structure of living things

There are millions of organisms on earth‚ and new ones are being discovered all the time‚ yet all living organisms perform one or both of two very important processes; cellular respiration and photosynthesis. Photosynthesis is performed by plant organisms and some bacteria‚ and cellular respiration is performed by all living organisms. These two processes are reliant on each other. Photosynthesis creates oxygen‚ which is used in cellular respiration. Cellular respiration in turn creates carbon dioxide

______________________________________ Date: ________________________ Photosynthesis Lab Gizmo website: www.explorelearning.com Class code: EFVNHTVRGY Gizmo Warm-up During photosynthesis‚ plants use the energy of light to produce glucose (C6H12O6) from carbon dioxide (CO2)‚ and water (H2O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they produce‚ but most of it

Light Lab Introduction: The purpose of this lab is to observe how influential light is to the construction and/or use of CO2 and O2 amongst plants. This can be examined by experimenting the effects of plants under both light and no light. In order to begin this experiment you must begin by wrapping the “BioChamber” with aluminum foil to prevent light from coming through to the leaves‚ however‚ once the lid has been covered you are to poke holes so you can insert the sensors. Next‚ you will

If you exercise regularly or if you are an athlete in training‚ you are trying to make your muscles work better. You want to be stronger if you are a weightlifter‚ you want to be able to throw a blistering fast ball if you are a baseball pitcher or you want to be able to finish strong at the end of a 26-mile race if you are a marathon runner. Adequate nutrition is a key component of sports performance. The greater the demands for increased performance both in training and competition‚ the higher

PL‚ DCP‚ DEC. Background: Photosynthesis is the reaction carried out by green plants to produce a supply of food. The reactions occur in the chloroplasts and require light energy. 6CO2 + 6H2O C6H12O6 + 6O2 In aquatic plants‚ the production of oxygen can be used to measure the rate of photosynthesis as the oxygen bubbles can be observed and counted or collected and measured. Your task is to design an experiment to investigate one of the factors
