The gas produced by fish that is utilized by aquatic plants is carbon dioxide (CO2). Fish excrete carbon dioxide as a byproduct of respiration, which dissolves in the water and provides a vital source of carbon for aquatic plants during photosynthesis. In turn, these plants release oxygen, which is essential for fish and other aquatic organisms. This cyclical relationship helps maintain a balanced ecosystem in aquatic environments.
Aquatic plants help to oxygenate the water - replacing the oxygen that's used by the fish - and the decaying fish waste.
Marine is used as an adjective when it is describing something found in or produced by the sea. (Example: marine life, marine plants) Aquatic is of or relating to water. (Example: aquatic sports, aquatic animals, aquatic plants)
The adjective "aquatic" is used to describe anything related to water or living in water. For example, it can refer to animals such as fish and amphibians, as well as plants that grow in or near water. Additionally, it can be used in contexts like aquatic sports, which involve activities performed in water, such as swimming or diving.
Dissolved oxygen in water is essential for the survival of aquatic organisms like fish and plants. It is used by these organisms for respiration, which is the process of extracting energy from food. Low levels of dissolved oxygen can lead to stress or death in aquatic life.
In a pond ecosystem, oxygen is produced through photosynthesis by aquatic plants. This oxygen is used by aquatic organisms like fish for respiration. Decomposers in the pond break down organic matter, releasing nutrients and consuming oxygen in the process. This cycling of oxygen is vital for maintaining the balance of the pond ecosystem.
Rooted aquatic plants can be found in areas with lower sunlight exposure. This is because the plants are used to having limited light because they're used to being in the water.
"Predominantly aquatic" refers to organisms or environments that are primarily associated with water. This term is often used to describe species that live most of their life in aquatic habitats, such as fish, amphibians, and certain plants. It implies that water is the main medium for survival and reproduction, although these organisms may occasionally interact with terrestrial environments.
I have a 75-gallon freshwater aquarium with several different species of plants. The one I found to be very popular and easy to grow either in the substrate or just let it float is water wisteria. My fish love to swim underneath the floating water wisteria. I wrote a paper on aquarium plants at the link.
The oxygen produced by plants during photosynthesis in water is released into the surrounding water. It can dissolve in the water and be used by aquatic organisms for respiration or released into the atmosphere if the water is disturbed.
Pondweeds can be both predators and prey. They function as predators in competing with other aquatic plants for nutrients and space and as prey in providing food sources for aquatic animals such as fish.
You should never put any terrestrial flower in water that has live fish in it you will poison the fish. If you want to put a plant in a fish tank or bowl, then the type of plant depends on the type of fish that you have (Which was not specified in the question). Marine fish can have many types of algae. Freshwater tropicals use various forms of tropical aquatic weed. For coldwater fish such as Koi there are flowering plants which can be used in ponds safely.
Chocolate mint plants can be used for flavoring food, from homemade wine to chicken and fish.
