Numerous campus associations and food service professionals around the country support this event each week by encouraging students to try new and exciting nutrient-dense meatless meals‚ including the University of Toledo. These schools also provide much needed support to local farmers by serving fresh organic fruits and vegetables. Showcasing a delicious vegetarian menu once a week allows students of all ages

weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements may also become available for use by the primary producers (i.e.‚ plants and phototropic microorganisms). Decomposition is an important step in the food chain and contributes to the nutrient cycling within an ecosystem. Most of the organic matter in an ecosystem ultimately

Introduction to Prokaryotes in Different Temperature Environments Angelina Orozco Biology 1108 Wednesday 7:30 am Abstract Prokaryotes are single-celled organisms that can survive in extreme environments. Bacteria is the more numerous type of prokaryotes. The group hypothesizes that the samples taken from different environments will all cultivate diverse morphology in fast growing rates in each environment. The aseptic technique was used to cultivate bacteria from different environments. The

If you want to live a longer life‚ health care should be your own responsibility. Firstly‚ we should get a balanced diet every day. A balanced diet is one which has the right amount of carbohydrate‚ proteins and other materials. Our bodies need nutrients to build up and repair tissues‚ thus‚ you are encouraged to eat plenty of vegetable and fresh fruits which are essential for our body. Besides‚ we should reduce our intake of high salt and sugar‚ for instance‚ fast food and process food. If we take

cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Eutrophication is a naturally occurring‚ slow‚ and inevitable process. However‚ when it is accelerated by human activity and water pollution called cultural eutrophication‚ it can lead to the premature aging and death of a body of water. Cultural eutrophication occurs when humans speed up the aging process by allowing excessive amounts of nutrients in such forms as sewage‚ detergents
