The correct answer for the question that is being presented above is this one: "<span>the mammal and the reptile." </span>The additional piece of information will be most helpful to Julia to properly build her phylogenetic tree is that i<span>t is trying to figure out on what tree it belongs to but it has some features of the animals but the 2 main ones: the mammal and the reptile.</span>
Heredity is the passing of physical characteristics unto the next generation a mouse for example might have brown fur the mouse he "gets busy with" also has brown fur likely hood of the baby having brown fur is a high likley hood hence you can say that the baby mouse has brown fur because of the heredity of his parents<span />
Because there is only a finite amount of energy. Energy is lost between each trophic stage. The top predator would gain the least amount of energy, shared between the least amount of organisms within the predator species. Typically there just aren't any other animals that can kill and eat the top predator, but there also wouldn't be enough of the top predator to eat so any species above them would quickly die out.
