Lithified ash (or ash mixed with pyroclastic fragments) forms a volcaniclastic rock called a Tuff.
- A form of rock called tuff is created when volcanic ash is blasted from a vent during an eruption.
- The ash is transformed into a rock after ejection and deposition. Tuff is defined as rock with an ash content of more than 75%, whereas tuffaceous refers to rock with an ash content of 25% to 75%.
- The thickness of tuff often decreases with distance from the volcano and is usually greatest close to the volcanic vent. The typical shape of a tuff deposit is that of a "lens," not a "layer."
- Tuff may also be thickest on the vent's side that faces away from the wind or on the side facing the direction of the blast.

I do not really understand what they are saying. Just IDK
Answer:
When an organism dies, decomposers decay the body extracting the last bit of energy from it. The common left over materials such as water, carbon dioxide, and minerals can then be reused by producers to make sugar through photosynthesis. Decomposers get energy through respiration, so they are heterotrophs.

<span>Cell signaling enables the cell to communicate and respond
to environmental changes. The environmental stimuli are transferred to the cell
as signaling molecules. Only the cell that has a specific receptor to these
molecules will respond to the stimuli as a result of the binding of the signaling
molecules to its receptor.</span>
