During the Tertiary period, dominant organisms included mammals such as early primates, rodents, horses, and whales. These mammals diversified and expanded in various environments as the climate changed, leading to the rise of new species and the extinction of others. Birds also continued to diversify during this time.
The Tertiary period happened after the extinction that took place during the Cretaceous period, so mammals saw a great diversification, the most notable of which was the movement from eating from trees to eating grass. Along with these mammals, birds also became the dominant animals in land ecosystems.

The K-T extinction occurred at the boundary between the Cretaceous and Paleogene periods, marking the end of the Mesozoic Era and the beginning of the Cenozoic Era. Therefore, it occurred at the end of the Cretaceous period and before the Tertiary period.
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
A tertiary consumer in the ocean is an animal that feeds on secondary consumers, such as large fish, sea turtles, or seals. These organisms are at the top of the food chain in marine ecosystems and play a crucial role in regulating populations of lower trophic levels. Examples of tertiary consumers in the ocean include sharks, killer whales, and large predatory fish like tuna.

During the Tertiary period, dominant organisms included early mammals, large birds, marine mammals like whales and dolphins, and diverse plant species. This period saw the rise of modern mammals, along with the evolution of grasslands, forests, and flowering plants. The Tertiary period also saw the decline of dinosaurs and the rise of more familiar animal groups.
