Most marine ecosystems do contain saltwater. Some bodies of water do contain freshwater, but they are not the majority.

What are the abiotic factors of marine biome?

Abiotic factors in the marine biome include temperature, salinity, sunlight, pH levels, dissolved oxygen, and water currents. These factors play a crucial role in shaping the marine ecosystem and influencing the distribution and abundance of marine organisms. fluctuations in these abiotic factors can have significant impacts on the health and functioning of marine ecosystems.


What happens to ecosystem of arriver if too much nitrates are dissolved in it?

Excess nitrates in water can lead to eutrophication, causing overgrowth of algae which depletes oxygen levels when they die and decompose. This can lead to fish kills and biodiversity loss as the ecosystem becomes imbalanced. It can also impact human health if the water is a drinking source.


What role do different plants in the ocean play in the marine ecosystem?

Different plants in the ocean play a crucial role in the marine ecosystem by providing food and oxygen for marine animals, regulating the carbon cycle, and maintaining the balance of nutrients in the water. These plants, such as phytoplankton and seaweeds, form the base of the marine food chain and support the overall health and biodiversity of the ocean ecosystem.


How does the presence of hard water marine environments impact the biodiversity and ecosystem dynamics of coastal regions?

The presence of hard water in marine environments can impact biodiversity and ecosystem dynamics in coastal regions by affecting the availability of nutrients and minerals for marine organisms. Hard water can lead to the accumulation of calcium and magnesium ions, which can influence the growth and survival of certain species. This can result in changes to the composition of the ecosystem and potentially disrupt the balance of species interactions.


Which biome has a salinity of .005 or less?

Freshwater biomes, such as rivers, streams, lakes, and ponds, typically have a salinity of 0.005 or less. These bodies of water contain very low levels of dissolved salts compared to marine or estuarine environments.
