Compare the two theories regarding the evolution of dinosaurs and then consider the cladogram above. although the two theories differ on the evolutionary path of dinosaurs, they agree that

they agree that dinosaurs, reptiles, and birds had belong to common ancestor.

Explanation:

The reptilians initially emerged before the dinosaurs, but after they never appeared less, the dinosaurs managed to take up the top niches in the food chain. On the other hand, the birds are in fact an evolutionary product of dinosaur diversification. The birds evolved from small bipedal dinosaurs that began to take on a new way of life and appearance in the course of time.

The dinosaurs have not evolved as a separate phylum that does not have close relationships with other animals, but rather shares a common ancestor with reptiles and bird likes.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
