A phylogenetic tree is a branching diagram showing evolutionary relationships among various living organisms based upon similarities and differences in their physical or genetic characteristics like the one above. In this case a human is more closely related to a mouse than a kangaroo, A platypus is more closely related to a kangaroo than a mouse, a human and a kangaroo share common features because of a common ancestor.
Answer:
See explanation
Explanation:
According to the second law of thermodynamics, energy transfer from one trophic level to another is not 100% efficient. Some energy is lost along the way from one trophic level to another.
The reason for this loss in energy is that the organisms at each trophic level harnesses the energy that they derive from complex organic matter to carry out their own metabolic processes.
Hence, only about 10% of the energy originally derived from complex food materials is passed on to the next trophic level.
Summarily, only about 10 percent of energy derived from food and stored in biomass in a particular trophic level is passed from one level to the next. This is commonly referred to as “the 10 percent rule”. This rule limits the number of trophic levels that can be supported by a given ecosystem.
