I have added some possible measurements to help. Read, analyze, and give complete answers to these questions. There are different types of marine reef environments. For example, these data may be based on known characteristics of equipment, such as the internal resistance of a battery.

The dissolved oxygen levels can cause the fish to suffocate and makes them susceptible to diseases. Naturally occurring hypoxic low oxygen conditions are not considered dead zones. The OMZ develops because organisms use the oxygen for respiration, but it is too deep to be replenished by photosynthetic oxygen byproducts or aeration from waves.

This occurs when a body of water is overstocked with organisms or if there is a large algal bloom die-off. What is the relationship between water temperature and dissolved oxygen? Oceanic benthic fish do not live at the greatest depths of the ocean.

Dissolved Oxygen

What would be the independent and dependent variables? I'm assuming that this means that there was more productivity in the initial bottle than in the light bottles—how could this be?

Rocks and Minerals Background In this lab, students perform common mineral identification tests on selected mineral samples. Five petri dishes are set up to collect results: Make an observation — Based on the data in Table 4, discuss what patterns you observe in regards to dissolved oxygen content and fish populations in the body of water?

Dissolved Oxygen Availability in ponds and lakes. Graph the data from Table 4: The amount of carbon dioxide used 2. In the ocean, coastal fish begin to avoid areas where DO is below 3.

The other five bottles were labeled according to the light intensity: In rivers and streams, dissolved oxygen concentrations are dependent on temperature. For the past two days, the clouds have come out at 3 pm and it has started raining at 3: To determine if the type of agar affects bacterial growth, a scientist cultures E.

Dissolved Oxygen and Water Column Stratification Stratification separates a body of water into layers. Bottle 3 had no screens, bottle 4 had 1 screen, bottle 5 had 3 screens, bottle 6 had 5 screens, and bottle 7 had 8 screens.

Examples of Freshwater Organisms and Dissolved Oxygen Requirements Minimum dissolved oxygen requirements of freshwater fish Coldwater fish like trout and salmon are most affected by low dissolved oxygen levels First, a tutorial describes procedures for determining the amount of dissolved oxygen in a water sample.

This is accomplished with a titration. This lab reinforces a set of procedures used in other science courses and scientific field work. Lab Dissolved Oxygen and Aquatic Primary Productivity Introduction • In an aquatic environment, oxygen must be dissolved in order to be available for use by organisms Key Concept 1: Dissolved Oxygen Availability: • Oxygen is essential for cellular respiration in most organisms • Availability is influenced by a variety of chemical and %(3).

Exercise 1: Data Interpretation Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life.
