Essay On Osmosis And Salinity

Discovering a new world below the ocean intrigues me. I have never been one for loving ocean creatures, but I do enjoy learning about the world below us. I found several facts interesting as I read the articles including: how osmosis and salinity functions, how seawater cells move, how pH affects the ocean, how decomposition works in the environment, how upwelling stirs up nutrients, and how water temperature affects organisms.
One of the interesting facts discusses why osmosis and salinity impact marine organisms. Osmosis relates to the amount of water that travels across cell membranes. During osmosis, the water travels from high concentration to low concentration until it reaches equilibrium. There are two types of osmosis reactions. The first label, osmotic conformers, includes organisms that cannot control osmosis and do not have body regulations to discrete chemicals. Because they do not have a regulator to excrete water, organisms’ cells explode if they are placed in a no salt environment. On the flipside, if an organism is thrown into a dense environment, then the water will flow out of the organism causing dehydration. Most of these osmotic conformers are plants and invertebrate animals, …show more content…
The reason is, when animals die and excrete feces it falls to the bottom of the ocean where it decomposes and goes back into the ecosystem. It is important because nutrients like nitrogen, phosphorous, and potassium are required for plant growth and plants are required for many other organisms to survive. Due to the necessity of light for plant growth, these nutrients are returned to the surface by upwelling. Scientists know that the ocean floor is rich in nutrients by the natural process of decomposition on the ocean floor, and by watching the ocean currents; they see the nutrients getting pushed up towards the surface where plants and animals are
