Rats are typically considered omnivores and occupy multiple trophic levels depending on their diet. In ecosystems, they generally function as primary consumers when feeding on plants and seeds, and as secondary consumers when preying on smaller animals or insects. Thus, rats can be classified primarily as primary consumers but may also act as secondary consumers in certain contexts.

2.2
The decibel level of a rat depends on the measurig distance to the rat. The closer you are to the mouth of the rat the louder the noise you can measure will be.
the bottom
Each tropic level is only able to use about 10% of the energy from its food. Because of this energy loss, there is usually not enough energy left to after a fourth tropic level to support anything higher.
the highest
lots
No
Roughly 10% of the energy from one trophic level is transferred to the next trophic level. This loss of energy occurs mainly through metabolic processes such as respiration and heat loss, resulting in less energy being available for the next trophic level.

Yes a tree does this.
