What is the relationship between temperature and dissolved oxygen in an aquatic ecosystem?
Temperature can affect the amount of dissolved oxygen in an aquatic ecosystem: warm water holds less oxygen than cold water. As temperature increases, the solubility of oxygen decreases, which can lead to lower oxygen levels in the water. This can impact the survival of aquatic organisms that rely on oxygen for respiration.
When temperature increases, any saturated gas concentration will decrease.
The higher the salinity, the lower the dissolved oxygen concentrations.
Water is still unchanged, no reaction between water and oxygen. They make a stabile mixture up till saturation (= maximum concentration)

What are the abiotic factors in an aquatic ecosystem?
Abiotic factors in an aquatic ecosystem include sunlight, temperature, water flow, dissolved oxygen levels, pH, salinity, and nutrient availability. These factors play a crucial role in shaping the characteristics and functions of the ecosystem and influencing the distribution and abundance of aquatic organisms.
What are 2 examples of abiotic factors in a lake ecosytem?
Two examples of abiotic factors in a lake ecosystem are temperature and dissolved oxygen levels. Temperature can affect the metabolic rates of organisms, while dissolved oxygen is essential for aquatic organisms to respire.
What are the four important factors of aquatic environments?
The four important factors of aquatic environments are temperature, sunlight, dissolved oxygen levels, and nutrient availability. These factors play a crucial role in shaping the ecosystem and influencing the distribution and abundance of aquatic organisms.
what is the difference between an aquatic and a terrestrial ecosystem?
An aquatic ecosystem is based on water, and a terrestrial ecosystem is based on land.
Which aquatic ecosystem is the warmest?
The warmest aquatic ecosystem is typically found in coral reefs, where water temperatures can reach up to 86°F (30°C) or higher. This warm temperature is ideal for the growth of the coral reef organisms and supports a high level of biodiversity.

What is the relationship between temperature and dissolved oxygen in a lake?
Temperature affects the amount of dissolved oxygen in a lake - warmer water holds less oxygen than cooler water. Generally, as water temperature increases, the solubility of oxygen decreases. This can have implications on aquatic life, as many organisms rely on dissolved oxygen for respiration.
Aquatic ecosystems are primarily determined by what characteristics of the overlying water?
aqua means water and when u say aquatic you mean water like ecosystem with diff.types of algeas,protist,plankton,and more.
What are the primary abiotic factors that affect life underwater?
The primary abiotic factors that affect life underwater are temperature, light availability (depth of water), dissolved oxygen levels, and salinity. These factors can impact the distribution and abundance of aquatic organisms and influence ecosystem dynamics.
What can dissolved oxygen tell us about water quality?
Dissolved oxygen levels in water can indicate its ability to support aquatic life. Low dissolved oxygen levels can stress or harm aquatic organisms, leading to negative impacts on the overall ecosystem health. Monitoring dissolved oxygen is important for assessing water quality and ensuring the well-being of aquatic ecosystems.
What are the four important factors of aquatic environments?
The four important factors of aquatic environments are temperature, sunlight, dissolved oxygen levels, and nutrient availability. These factors play a crucial role in shaping the ecosystem and influencing the distribution and abundance of aquatic organisms.
Importance of dissolved oxygen in water?
Dissolved oxygen is crucial for aquatic life as it is necessary for respiration in fish and other organisms. Its presence indicates the overall water quality of an ecosystem. Low levels of dissolved oxygen can lead to stress or death in aquatic organisms and impact the health of an aquatic environment.
What are the four main factors that affect aquatic ecosystems?
Water temperature: Affects the metabolic rates of aquatic organisms and the solubility of gases like oxygen. Nutrient levels: Excess nutrients can lead to eutrophication, while nutrient deficiencies can limit plant and algae growth. Pollution: Chemicals, plastics, and other contaminants can harm aquatic organisms and disrupt the ecosystem. Habitat destruction: Alterations to the physical structure of aquatic environments, such as dams or dredging, can impact species diversity and ecosystem function.
What best describes dissolved oxygen and temperature?
Dissolved oxygen is the amount of oxygen present in water, which is essential for aquatic organisms to survive. Temperature affects the solubility of oxygen in water, with colder water holding more dissolved oxygen than warmer water. Therefore, temperature plays a crucial role in determining the availability of oxygen for aquatic life.
What would happen if dissolved oxygen percentage falls below 8?
When dissolved oxygen falls below 8%, aquatic organisms may experience stress or die due to oxygen deprivation. This can disrupt the ecosystem balance, leading to fish kills and other negative impacts on the aquatic habitat. Monitoring and maintaining appropriate levels of dissolved oxygen is crucial for the health of aquatic organisms.
What is a dangerous level of dissolved oxygen?
A dangerous level of dissolved oxygen in water is below 4-5 mg/L for most aquatic species. Low levels can stress or kill aquatic organisms, disrupt the ecosystem balance, and indicate poor water quality.
