1. Living organisms play an important role in the recycling of many elements within an ecosystem. One such way this idea can be proven is through the study of carbon in an ecosystem. Plants‚ for starters‚ are a major part of this carbon cycle. During photosynthesis‚ plants remove carbon dioxide from the atmosphere and release oxygen as a waste product. Another major contributor to this vital cycle is the human being. The average human being goes through respiration each day to help maintain

“Scientists have recently proposed a reorganization of the phylogenetic system of classification to include the domain‚ a taxonomic category higher than the kingdom category.” A. The three-domain system allows for the conclusion that the previous five kingdoms were more connected than was believed. Out of the five previous kingdoms: Animalia‚ Plantae‚ Protista‚ Fungi‚ and Monera‚ four of the five kingdoms were placed in the same domain- Eukarya. The one remaining kingdom was separated into

Based off the information given in table 1 a number of trends in characteristics can be identified from the Papio anubis to the Homo neanderthalensis. There is a significant trend towards a taller and more vertical posture; this is supported by information gathered on locomotion. Starting from the monkey Papio anubis on the far left of the table‚ it’s movement is quadruped as it moves on all four limbs. Moving right of the table a transition from quadrupedal to bipedal becomes noticeable as the Pan
