differ in various ways from other birds. There are more than three-hundred species of hummingbirds. Hummingbirds play a very important role in the ecosystem. Hummingbirds are pollinators and control insects. Hummingbirds can hover in mid-air why consuming nectar from deep flowers. The male humming bird contributes very little in reproduction. Human activities are responsible for some of the deaths of these magnificent species. Hummingbirds are found only in the Americas. Their etiology is…

environment and classified by their taxa, and Shannon-Simpson indices were produced from these data to analyze the differences in diversity between the two environments. It was found that pools have a significantly greater species abundance, while riffles have a significantly greater species evenness. These results can be used to further examine changing abiotic factors,…

In the movie Spiderman, the protagonist Peter Parker is a geeky, introverted, intelligent high school boy who gets bit by an engineered spider during a field trip to a lab. After the biting of the spider, Parker turns into a stronger and confident person who possesses spider-like qualities. Throughout the movie it is clear Spiderman’s legacy is that he wishes to protect civilians, he can be considered as a superhero vigilante or be considered as a criminal. Parker develops super speed, strength,…

evolution and natural selection. The strongest and most important organisms do not survive over the generations. Although evolution occurs due to fitness in an individual or individuals of a species, an organism cannot survive over generations. Fitness is achieved through variations in populations of species through genetic differentiation (Scottville “n.d.”). Since the life cycle of all living organisms is to be born, survive, mate, and die, it is impossible for an organism to live through…

impact that it has on forest are drastic such as loss of diversity because birds live in trees. The less trees that there are the less chance of survival a bird species has against the transformation of the forest to agriculture or other ways humans can exploit. The more individuals and corporations cut down trees, the more…

universally recognized by their massive bodies, stumpy legs and their horns. - They are renowned for having poor eyesight, but their senses of smell and hearing are well developed. - There are five species and 11 subspecies of rhino; some have two horns, while others have one. The biggest of the five surviving species are Africa's white rhino and Asia's greater one-horned rhinos. - All of the different…

Birds are a group of animal which consist of many species, all of which play various roles in several ecological niches. Birds are considered ‘biologically successful’ due in fact to the number of species present. Currently, there are approximately 10,000 species of birds, which is almost double the amount of species of mammals or amphibians. The differences which separate birds from mammals and make them more successful are the presence of large yolked eggs, which support the offspring until…

Although some people don't see the problem in having killer whales do shows, it can be argued that orcas in captivity and having them do shows has multiple issues. One reason is that orcas can be driven crazy when kept in captivity. Second of all, killer whales need more space than any aquarium can give them. Last but not least, orcas in captivity aren't as healthy as orcas in the wild. I believe that killer whale shows should be banned. To begin, killer whales or orcas can be driven insane…

Throughout millions of years species have learned to adapt to the ever-changing planet they call home. Some species have survived the change and others have not and went extinct. The National Geographic documentary on the Wild Amazon Rainforest offers some insight on how the creatures of the forest and the river have adapted throughout time. Every year new species is being discovered, whether it be plants or animals. If the environment is changing slowly the animals and plants that live in the…

and some cold, that have created the unique ecosystem on the islands. Because the many plants and animals that have arrived there over the past four million years are isolated from their relatives on the mainland, they have evolved into different species. The giant tortoises, swimming iguanas, small penguins, flightless cormorants and more are just a few of the unique and fascinating animals that live there. The Galapagos have both Spanish and English traditions, and the islands each have two…
