The process in which the floors of a building collapse on one another is known as a pancake collapse. This will make the correct answer here B, pancaking.
        
             
        
        
        
Answer:
Denitrification process occurs when the soil bacteria use nitrate for the respiration of oxygen in the air. These nitrates are converted to nitrogen gases.  
<u>Explanation:
</u>
<em>The denitrification process mostly occurs in warm nature rapidly, wet soils with sufficient of nitrate. Denitrification process only occurs when the nitrate is present.</em> <em>The denitrification is in sewage treatment and it is beneficial process, the problem considered in agriculture farmers to increase their crop yields because they are applying nitrogen fertilizers to the land. </em>
<em>Denitrification process increases from cropland and it is responsible for increases the amount of nitrous oxide in the atmosphere.  The denitrification process plays an important to recycling of nitrogen for healthy soil, microbial and for plant growth, and animal’s health.</em> The impacts of global warming are due to the process of denitrification through loss of nitrous oxide.
 
        
             
        
        
        
1. Camouflage 
2. Competition 
3. Competition 
4. Symbiosis 
<h3><u>Explanation</u>:</h3>
The camouflage is defined as the property of the living organisms that make them to prepare their body to perfectly match with their surroundings so that they cannot be recognised by their hunters. This makes them survive more in an environment with full of competition. 
The competition is an interaction between the organisms where in a particular environment, different organisms compete for a particular prey for their living. Here the theory of the survival of the fittest work. 
The symbiosis is an interaction between two or more species which leads to benifit of both the species in their living. Here one species help other in a form and other species do the same. There's benifit for both in the interaction. 
 
        
             
        
        
        
A polymer is made up of monomers. A monomer is a unit that occurs in repetitive chains. Lipids do not occur in repetitive chains, so they are not classified as monomers. Since they're not monomers, they can't make up polymers, either.
