Topic: Silver is an ancient mineral that dates back since prehistoric times. One thing that makes silver so special is that it was one of the first five metals that we started to use. Silver is found in almost every electronic device there is‚ and as time progresses the usage of it increases‚ unfortunately the amount there is left decreases. How is it created or source of the mineral? (5) Silver is not originated from Earth‚ as it happens it came from space. Many elements were formed in the big

example of a food chain that exists in nature. Grass-mouse-snake-hawk 2. In an ecological pyramid‚ what happens to energy‚ biomass and # of species as you move up? Why? They all decrease because energy is lost as it moves up each trophic level. Each trophic level requires more energy to sustain it‚ increasing competition for resources and causing number of organisms to drop. 3. What is biomass? Biomass is the total mass of dry organic matter per unit area. 4. In an ecosystem‚ can there be more carnivores

Data Collection QNT/351 July 10‚ 2014 There are many times when companies have to collect data to come to a conclusion about an issue. The data may be collected from their employers‚ their competition or their consumers. BIMS saw that there had been an average turnover that was larger then what the company had seen in the past. Human Resources decided that they would conduct a survey to see what had changed in the company from the employee’s point of view. They attached
