Biological Oxygen Demand (BOD) is a measure of?

How much oxygen is needed for survival of aerobic bacteria
The extent to which rivers or lakes are polluted with organic waste compounds
We have seen that energy is essential for life on earth. All organisms need energy to maintain their cellular processes. There are two basic ways of generating energy de novo, at the base of food webs. Describe the two primary ways that autotrophic organisms generate energy, including the original source of energy and the primary organisms that carry out each process.
High levels of certain plant nutrients in runoff can lead to rapid growth of algae (an algal bloom) in aquatic ecosystems. These algal blooms are generally followed by algal death and decomposition, which consumes large amounts of dissolved oxygen in the water and results in oxygen levels insufficient to support aerobic respiration. This process is known as eutrophication. The amount of algae present in a body of water can be estimated from the amount of chlorophyll a in a sample of the water. A researcher studying eutrophication collected samples at different times of the year in a freshwater ecosystem. The samples were analyzed for total nitrogen and chlorophyll a concentration (Figure 1) as well as total phosphorus and chlorophyll a concentration (Figure 2).
Which of the following was the dependent variable in the researcher’s study?
a.The variance of the data points from the trend line
b.The slope of the trend line showing the rate…

- Methanopyrus kandleri and Pyrolobus fumarij are bacteria that live near hydrothermal vents under the oceans. Temperatures at these vents can reach well over 100 degrees Celsius. Both organisms obtain energy from hydrogen but Methanopyrus kandleri grows best at 98 degrees Celsius while Pyrolobus fumarij prefers to reproduce at temperatures above 100 degrees Celsius. These bacteria provide the base of a food web at the bottom of the ocean floor. What questions could a student ask in order to investigate this difference between the bacteria? A. What kind of heat tolerance do other nearby organisms have? B. Does the Methanopyrus kandleri live farther away from the vent than the Pyrolobus fumarij? C. Does Methanopyrus kandleri have a thicker cell wall than Pyrolobus fumarij? D.
