Legal protection and conservation plan for these endangered subspecies should be established. However‚ organic evolution has been taking place for 3.5 billion years. It is impossible to study every living organism from an individual level. Biologists group and classify living and extinct organisms for many reasons such as to establish a common language or reference point or to develop a system for counting‚ storing‚

2002)Ocean and coastal marine systems are also affected by changes in climate‚ through increases or decreases in water levels. When water levels are altered naturally or unnaturally‚ nutrients and oxygen levels vital to the maintenance of marine organisms‚ are changed. A myriad of marine species including some birds‚ are impacted by the availability of marine food sources and will have long term implications regarding freshwater and seafood supply for humans as well as animals. Due to increases in

variety of interactions between living and nonliving organisms.One observation was the nonliving organisms help the living organisms meet their needs such as living conditions. When I say living conditions I refer to climate changes and geography in the marine life. Nonliving and living organism interact with each other in many different components. When I was observing the river I saw how organisms have to have living and nonliving elements in order to have a survival of that specie for the reason

Unknown Unknown Bacteria #14 LeNaiya Kydd 4/2/2014 Abstract In order to be able to identify the unknown organism that was given to us‚ we had to conduct a number of different tests. These biological tests are used because they help us be able to identify the properties of the unknown we have and be able to compare our observed results with actual results of all the potential organisms. When all of the data of the test are put together it is easy to figure out the identity of the unknown. Each

Understanding the range of life on the planet we call Earth. This magnificent planet is full of living organisms everywhere you look. As cells build upon each other in the structure of life‚ they create the different forms known as emergent properties. From the tiniest cells‚ the beautiful colors of the fungi to the amazing human body. The extensive study

beginning inhabitants of the world had no mutations in their genetic composition. His publication had two major points. The first being the modern organisms presently inhibiting the earth‚ differ from their ancestral species by a process called evolution. The other point he made was that of natural selection‚ as it is the mechanism for evolution. The organisms inherit traits from ancestors who were able to survive specific environmental conditions‚ passing these traits on to their offspring. Darwin

above food web describes how all the major categories of organism can work to together in an ecosystem. First let’s describe the producers‚ these are plants and trees the produce energy into the ecosystem. Next the consumer‚ there are three different types herbivores (deer)‚ carnivores (birds)‚ and omnivores (bears). Then the last category is decomposers‚ which happen to be like a consumer but they feed off animal dropping and dead organisms. This way it can break down and return the nutrients to
