From the bottom trophic level to the top trophic level, the number of organisms decreases. Because there are fewer organisms present in each trophic level, there is typically a smaller amount of biomass in each level as well. Each trophic level in a food chain or food web can be represented in the ecological pyramid.
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
So an object denser than water will sink
Each enzyme has a particular shape so that it can attach to a substrate (molecule). So, during a chemical reaction, the enzyme and substrate join together, and then the substrate is changed in some way depending what the chemical reaction is doing? hope this helps a little.

Central nervous system is one of the parts of nervous system that includes brain and spinal cord.
The brain is located in the skull and serves as the controlling and processing center of the body. For example, visual processing takes place in occipital lobe of the brain, planning, reasoning, speech, movement, emotion et cetera are processed in frontal lobe of the brain.
The spinal cord is attached to the brain through brain stem. It connects the central nervous system with peripheral nervous system. It also in regulation of reflex actions.
They would be further apart than a solid and they would be closer together than a gas.
