Discuss the relationship between the terms (individual) organisms, population, community, and ecosystem. Define the terms and give an example of a real-life ecosystem from the point of view of one of its inhabitants (an individual bacterium, let us say) as it "ponders" the higher-level structures.arrow_forwardWhat are the three ways microbes can interact symbiotically with humans?

- As revealed by different colony types, would there be a different species of bacteria/microorganism that can be found in any given environment?arrow_forwardBacterial growth depends on many environmental factors, including the temperature of the environment. Since microbes can survive in a certain range of temperatures and will thrive at a temperature, understanding these variables allows for control of their growth. This understanding can be used, for example, to preserve certain foods or to treat infections. This lab simulation will use an instrument called a spectrophotometer. This instrument quantitatively measures the amount of light that is absorbed or transmitted by molecules in solution. Microbial populations grow at different rates based on temperature. One way to measure growth is by turbidity measurements. When bacteria multiply in a broth culture they turn the clear solution cloudy, or turbid. a) in your own words explain the proper steps to Inoculate 5°C sterile broth tube using aseptic techniquearrow_forwardWhich of the following best describes the pattern of microbial death? Not all of the cells in a culture are killed. O The cells in a population die at a constant rate. All the cells in a culture die at once. O The pattern varies depending on the species.arrow_forward
