When an environment is hypotonic, the cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.
WHAT IS TONICITY:
- Tonicity refers to the ability of a solution to cause the inflow or outflow of water in a cell. Tonicity of a solution can either be: hypotonic, hypertonic or isotonic.
- Hypotonic: This is when a solution has less concentration of solute or more concentration of water than its surroundings.
- Hypertonic: This is when a solution has more concentration of solute or less concentration of water than its surroundings.
- Isotonic: This is when the solute concentration between a solution and a cell is balanced or equal.
Based on osmosis, which is the movement of water from a region of higher concentration to a region of lower concentration through a semipermeable membrane, water will move from a hypotonic environment into a cell containing more solute.
Therefore, When an environment is hypotonic, the cell has more solute, so solvent moves from outside the cell to inside, causing the cell to swell.

Explanation:
erosion is caused physically by earthquakes and stuff...hope this helps:))
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
