Energy moves through an ecosystem from plant to apex predator. The saw palmetto is a plant, the woodrat is a herbivore so it comes second, and the bald eagle is the apex predator.
The era is characterized by having one of the most diverse environment that the earth could have ever seen, as there were number of species of dinosaurs and there were different plant life as well, and the climate was not so cold to live for the different organisms.
As, the life on earth flourish even there were organisms found on large scale inside the arctic circle.While, the level of CO₂ increased inside the Mesozoic era. Along , with which the extinction of about 96 percent of life made it very difficult for the rest of the organisms to survive and thus there were now mutations happening inside the different organisms genome.Along, with that the way of reproduction was greatly changed inside the plants, as more effective form of flowering plants were evolved.
As, for the animals new species with the increase level of survival instinct were evolved from old simple ones across the globe.
The correct answer is crossover because mitosis is he reproduction of daughter cells and mutations can help evolution and sexual reproduction is helpful to changing for evolution So the answer is C. Crossover
