this can be extremely important for people who are reliant on subsistence irrigation farming. Wetland ecosystems are able to assimilate some biodegradable waste products‚ providing important treatment capabilities for substances such as excess nutrients and sediments‚ and improving water quality for downstream users. Some wetlands trap toxic pollutants such as heavy metals‚ which can later be removed for safe disposal‚ if necessary. The value of these services may be considerable‚ since technical

“The Great Lakes Research Center (GLRC) provides state-of-the-art laboratories to support research on a broad array of topics. Faculty members from many departments across Michigan Technological University’s campus collaborate on interdisciplinary research‚ ranging from air–water interactions to biogeochemistry to food web relationships.” Its main purpose is to educate students‚ faculty‚ teachers‚ and others about the Great Lakes water basin. The Great Lakes Research Center has many education and

Biology Journal 1 Biotic factors are all the living factors in an environment (Plants). While abiotic factors are all non-living factors in an environment. The three types of interactions that occur are biotic-biotic (Betta Fish eating Hornwort‚ or Fly eating leaves)‚ biotic-Abiotic (Plants-Sunlight‚ or Betta Fish- Fish Food)‚ and abiotic-abiotic (water eroding rocks‚ or sunlight heating the soil). The biotic factors I control are what seeds i plant‚ and the type of fish i buy. The abiotic factors

Earthworm feces aid in provision of minerals and plant nutrients in an accessible form. After an animal has digested eaten material‚ the remains of that material are expelled from its body as waste. Though it is lower in energy than the food it came from‚ feces may still contain a large amount of energy‚ often

ecosystem. According to UNDP.org (2010)‚ the activities of microbial and animal species – including bacteria‚ algae‚ fungi‚ mites‚ millipedes and worms – condition soils‚ break down organic matter‚ and release essential nutrients to plants. These processes play a key role in the cycling of such crucial elements as nitrogen‚ carbon and phosphorous between the living and non-living parts of the biosphere. The gray wolfs of Yellowstone National Park are an example of what happens when one species is eliminated

of the cell cycle stage of its neighboring cells. Cells that are synchronized are artificially induced to cycle in a homogeneous manner. The ability to continue cycling is an important distinction between a homogeneous population of cells created by synchronization and one created by blocking cells from cycling. Blocking cells from cycling may also result in a homogeneous population of cells at a particular stage of the cell cycle‚ but often results in death of the cell. In contrast‚ the purpose of
