Classification and Marine Biodiversity Important Background Information that you need to know and understand: (Understand the Key Concepts) Key words: binominal system of naming; science of classification is taxonomy; species; levels of classification (know them); dichotomous identification key; 5 kingdoms; etc… CLASSIFICATION Our oceans have a great variety of life forms. Thousands of new species are discovered each year. We need to identify‚ name‚ and know the biology of all the marine

Evaluate the relative roles of natural succession and human activities in the creation of ecosystems within the British isles. (40 marks) An ecosystem is a biological community of interacting organisms and their physical environment. Ecosystems can be changed by both human activity and natural succession. Ecological succession is the observed process of change in the species structure of an ecological community over time. The time scale can be decades (for example‚ after a wildfire)‚ or even millions

of hectares underground‚ the diversity and extent of life on Earth is dazzling. In its life and reproduction‚ every organism is shaped by‚ and in turn shapes‚ its environment. Ecological scientists study organism-environment interactions across ecosystems of all sizes‚ ranging from microbial communities to the Earth as a whole.” (Malmstrom‚ 2010) Organisms occupy just about every environment here on Earth. Every environment offers resources and constraints that mold the appearance of the species

In the article‚ the author argues that Hong Kong people and government should consider biodiversity conservation when developing lands for housing because development would cause irreversible harm to wetland and biodiversity located in some of the lands. The author also argues that one should never replace biodiversity conservation (concept of conservation biology) with ecosystem functioning and services (concept of conservation

changing. We might never see the small alterations happen‚ but many years later‚ changes will surely be visible. Over time small changes add up and soon the whole ecosystem is different. This slow change in the land and habitat is called ecological succession. Animals‚ plants‚ and weather are some factors that cause this type of change in an ecosystem. Ecological succession begins with a pioneer community. In many cases lichens are the "pioneers." Lichens break down rocks‚ making soil‚ so that plants can

E > H > B The Oil Spill‚ due to the mismanaged oil drilling by British Petroleum (BP)‚ in the Gulf of Mexico‚ has turned into one of the worst environmental disasters to happen to an ocean ecosystem of all time. Although many people only notice the effects on the hydrosphere‚ which include the oil going almost a mile deep under the sea‚ destroying the sediment and rock on the ocean floor‚ as well as disrupting coastal patterns‚ many have not realized the drastic effects on the biosphere

paper will review the components of primary and secondary succession as describes on page 68 and 69 of the textbook Environment. The scope of this paper will attempt to address how biotic and a biotic components effect the balance of the ecosystem‚ and how ecosystems go through the cycles of progression. When discussing primary succession‚ one must first understand what primary succession in point of fact means. In the case of figure 4-4 on page 68‚ the text is and visual example in question is of

Schaefer Dr. Chad Scholes Biology II February 24‚ 2014 Aquatic Ecosystem Function Aquatic ecosystems account for the majority of the earth‚ and affect not only the organisms living within them‚ but all other organisms as well. Because these ecosystems are so vast‚ and have such impacts‚ it is important to understand how they function. To determine how an ecosystem is functioning‚ the stability of the ecosystem is taken into consideration. Stability is defined as the tendency of a system

Declining Biodiversity Deanna Garrett ENV495 Jeanne Lambert May 6‚ 2013 Declining Biodiversity Biodiversity is important in ecosystems because every life form works together in order for them to function. When these ecosystems are disrupted or altered‚ or even lacks biodiversity‚ it poses major threats to all the life forms in it‚ whether it happens quickly or over a long period of time. These threats include atmospheric pollution‚ weather catastrophe‚ climate changes‚ or even man-made
