Diffusion is the net movement of anything (for example, atom, ions, molecules) from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration.

The concept of diffusion is widely used in many fields, including physics (particle diffusion), chemistry, biology, sociology, economics, and finance (diffusion of people, ideas, and price values). The central idea of diffusion, however, is common to all of these: an object (for example, atom, idea, etc.) undergoing diffusion spreads out from a point or location at which there is a higher concentration of that object.

A gradient is the change in the value of a quantity, for example, concentration, pressure, or temperature with the change in another variable, usually distance. A change in concentration over a distance is called a concentration gradient, a change in pressure over a distance is called a pressure gradient, and a change in temperature over a distance is called a temperature gradient.

The word diffusion derives from the Latin word, diffundere, which means "to spread out."

A distinguishing feature of diffusion is that it depends on particle random walk, and results in mixing or mass transport without requiring directed bulk motion. Bulk motion, or bulk flow, is the characteristic of advection.[1] The term convection is used to describe the combination of both transport phenomena.

If a diffusion process can be described by Fick's laws, it's called a normal diffusion (or Fickian diffusion); Otherwise, it's called an anomalous diffusion (or non-Fickian diffusion).

How are land, air, water and living things impacted by too much carbon dioxide?
choli [55]

Answer:

- In terrestrial environments: increasing CO2 levels cause an increased photosynthetic rate

- In aquatic environments: increasing CO2 levels cause an increase in water acidity  

- In both terrestrial and aquatic environments: increasing CO2 levels lead to an overall increase in the average temperature (global warming)

Explanation:

In terrestrial ecosystems, rising carbon dioxide (CO2) levels increase the rate of photosynthesis (since CO2 is one of the reactants in photosynthesis), thereby also increasing plant growth. Moreover, in aquatic ecosystems, rising CO2 concentrations increase the levels of this gas dissolved on the surface of the oceans. This increases the acidity of the oceans, thereby modifying habitats and food web structures. The increasing acidity of the oceans also reduces the amounts of carbonate, which difficult for aquatic species (e.g., corals) to form their shells/skeletons. Finally, CO2 is a greenhouse gas that contributes to the increase in the average temperature by absorbing solar radiation that would otherwise have been reflected by the Earth's surface, and this increase in the temperature negatively affects life in both terrestrial and aquatic environments.

How is carbon moving between the air and found it decreasing in the  diodome
scoray [572]

Answer: They read articles about photosynthesis. They investigate photosynthesis, energy storage molecules, and carbon in the sim. ... This process moves carbon from biotic to abiotic matter. Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.
