Ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚ they can come in any size but usually encompass specific‚ limited spaces (although

The Effects of Improper Garbage Disposal Tossing everyday items into the trash can seem like second nature to many people. If you are implementing recycling techniques into your lifestyle‚ you are taking a positive step toward helping the environment. Learner.org notes that in the U.S. alone‚ over 230 million tons of trash is produced each year. Less than 25 percent of that waste is recycled and the rest ends up in landfills‚ incinerated or in ditches and roadsides. Improper garbage disposal isn’t

Abstract Lake Windermere :- A habitat to the Arctic Charr (Salvelinus alpinus). Windermere can be described as a glacial ribbon lake‚ which has experienced a lot of excavations and over deepening by past glaciations. Lake Windermere is (17 km) in length and over (1.5 km) in width. This is situated in the Lake District of Cumbria in the NW of England. It is (60 m) deep and falls withinthe wooded hills near Scafell and other mountains. Windermere is the largest lake in England. It is fed and replenished

For example‚ Palumbi stated that the bacteria can affect people can cause skin rashes‚ which can cause algal blooms. The more chemicals that get in our tides‚ the

Option F: Microbes and Biotechnology Diversity of Microbe F.1.1 Outline the classification of living organisms into three domains. Three domains of living organisms: 1. Archaea - very primitive; live in extreme habitats 2. Eubacteria - more advanced 3. Eukaryota - all life forms with eukaryotic cells (have a nucleus) Use of ribosomal RNA sequences for classification rRNA is found in all cells rRNA is easy to isolate Analyzed to determine the exact sequence of nucleotide bases

Further south then are areas of oxygen depletion‚ caused by chemicals using up oxygen and by algae blooms‚ caused by excess nutrients from algal cell death and decomposition. Fish and shellfish kills have been reported‚ because toxins climb the food chain after small fish consume copepods‚ then large fish eat smaller fish‚ etc. Each successive step up the food chain causes
