What is the difference between marine and freshwater ecosystem is the presence of?
The main difference between marine and freshwater ecosystems is the salt concentration in the water. Marine ecosystems have high salt concentrations, whereas freshwater ecosystems have low salt concentrations. This difference in salinity influences the types of organisms that can thrive in each ecosystem.
Which zone is found in both marine and freshwater ecosystems?
The intertidal zone is found in both marine and freshwater ecosystems. It is a transitional area between the land and water, subject to periodic submersion and exposure. Organisms in this zone must adapt to fluctuations in moisture and temperature.
How does algal growth caused by agricultural waste kill marine organisms?
BY Blocking the Sunlight and Depleting oxygen
Which of the following was not characteristics of earth before the oceans formed?
Land was not covered by water, there were no marine organisms present, and the atmosphere did not have oxygen.
Dissolved oxygen in the ocean water does what?
Dissolved oxygen in ocean water is crucial for the survival of marine life. It is used by fish and other aquatic organisms for respiration. Low levels of dissolved oxygen can lead to stress or death among marine organisms.
Miroscopic organisms in waters of freshwater and marine environments?
Plankton
What are tiny organisms that float near the surface of freshwater and marine envioments called?
the answer is phytoplankton or plankton
Why are nitrogen oxygen and carbon dioxide important to marine organisms?
Nitrogen is important for marine organisms because it is a key component of amino acids and proteins. Oxygen is vital for respiration in marine organisms, enabling them to extract energy from food. Carbon dioxide is involved in photosynthesis, where marine organisms like phytoplankton use it to produce energy and oxygen.
How do nekton moved?
nektonThe collection of marine and freshwater organisms that can swim freely and are generally independent of currents, ranging in size from microscopic organisms to whales.
How do water oxygen levels affect marine organisms?
Water oxygen levels are crucial for the survival of marine organisms as they rely on oxygen for respiration. Low oxygen levels, known as hypoxia, can lead to stress, impaired growth, and even death in marine organisms. Some species have adaptations to low oxygen levels, while others may be more sensitive and face population declines in areas with poor oxygenation.
What is the difference between marine and freshwater ecosystem is the presence of?
The main difference between marine and freshwater ecosystems is the salt concentration in the water. Marine ecosystems have high salt concentrations, whereas freshwater ecosystems have low salt concentrations. This difference in salinity influences the types of organisms that can thrive in each ecosystem.
Who studies organisms in water?
In sea water it's a marine biologist. If the water is fresh it's just a freshwater biologist.
Are desmids freshwater marine or both?
Marine
Does krill produce oxygen?
Krill primarily consume phytoplankton and do not produce oxygen in a significant amount. The oxygen produced by marine organisms mainly comes from photosynthetic organisms like phytoplankton and seaweed.
What is the difference between freshwater and marine aquarium?
I think marine aquariums are saltwater unlike freshwater that do not have saltwater
What two major factors do marine organisms depend on for their survival?
Marine organisms depend on water temperature and oxygen levels for their survival. Water temperature affects their metabolic rates, behavior, and reproduction, while oxygen is essential for their respiration and overall health.
How does ciliophora role in the environment?
their role in the environment is basically just feeding on the bacteria, algae, and other smaller, organisms in their marine and freshwater habitats
