what is the significance of diffusion and osmosis in living organism ?give one example in support of your answer​
olasank [31]

Answer:

Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).

Examples of where diffusion is important;

In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.

Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.

The collection of organisms and their nonliving surroundings that functions as a unit is called:__________.
Wewaii [24]

The collection of organisms and their nonliving surroundings that functions as a unit is called ecosystem. There are two kinds of ecosystem:

  • Aquatic ecosystems (ecosystems dependent on water)
  • Terrestrial ecosystems are those found on land.

Biomes are broad classifications of terrestrial ecosystems based chiefly on climate. Tropical rain forests, savannas, deserts, coniferous forests, and tundra are a few examples of nonliving surroundings in terrestrial biomes. According to the definition of an aquatic ecosystem, it is a water-based environment. Aquatic environments are of two types: marine ecosystems and freshwater ecosystems. The organisms included different fish species, crayfish, turtles and sharks etc.
