Mud flats are a vital type of marine habitat that provide several different functions for various marine invertebrates. They provide both permanent and temporary homes to small invertebrates including several species of worms, crabs, snails, and other benthic fauna. These organisms are responsible for the breakdown of organic materials often deposited here, as well as filling the role of prey for many predators that hunt in the shallow waters (Dyer et al., 2000). Mud flats are most often…

plant species, Tagetes patula (marigold). This rationale supports the following predictions: that, in the presence of an increasing concentration gradient of gasoline contaminant, Brassica rapa will display a greater increase in plant height, dry biomass and rate of leaf growth in comparison to Tagetes patula. As Tagetes patula experiences a decrease in these three characteristics with the increase of oil contamination, it will display a decrease in plant fitness, as constituted by these…

In the heterotrophic production, microalgae are grown in the dark and energized by organic carbon substrates in mixing fermenters or bioreactors. With no necessity for light energy, the system can have smaller surface-to-volume ratio of the reactor. The design can be minimal and easier to control its physical conditions due to no exposure to the outside light source. However, this system requires more total operational energy than the photoautotrophic mechanisms, since this process requires the…

in one way or another. The fossil fuels are not renewable, meaning they will run out someday. Nuclear power makes heat using a nuclear reaction. It is renewable, but it gives off nuclear waste. Biomass uses organic material to make energy.…

classic fuel sources (i.e. coal, shale, natural gas) because it uses natural resources that has the ability to be consistently replaced; thus it is also termed “renewable energy.” “Biofuels” are a specific class of renewable energy that refers to biomass (versus other natural resources like sunlight) or harvested metabolites from living organisms that can be converted into a source of alternative energy. In addition to being renewable, these fuel sources also have lower greenhouse gas (i.e. CO2,…

One of the main abiotic factors influencing the distribution of biomes is global atmospheric circulation. Global atmospheric circulation is the mass movement of air around earth caused by thermal energy. This mass movement of air causes three distinct atmospheric circulation cells to form, these are the Hadley Cell, Ferrel Cell and Polar Cell. Between these three cells is a dynamic area called the Intertropical Convergence Zone. Persson (2006) tells us that the Hadley Cell is caused by solar…

different conditions such as sampling events and sites. In respect to our hypothesis in which the increase in resource quantity increases body size and biomass, we have confirmed it partially. In general, female insects tend to have a larger body size than the males, and the difference between male and female is more pronounced when observing the body biomass (Colgoni & Vamosi 2006). However, our system pointed out an opposite pattern for both species, corroborated by the longevity experiment…

disease by the indoor pollutants [1,6,7]. In Bangladesh to reduce emission by cooking with biomass fuel in the rural areas, use of improved stove for cooking purpose has been promoted by different agencies. There was also some studies related to use of biomass fuel by the rural people and respiratory problems and it was revealed that respiratory problems were more common among the females who used biomass fuel [13,14]. However no such activities have been noticed among the urban households.…

that are constantly refilled. This type of energies are created by using sunlight, geothermal heat, tides, wind, water and different types of biomass. This type of energies can’t be drained or weakened and is continuously renewed according to the conditions (Daniel Ciolkosz, P.E.,). Some of the benefits and importance of using renewable energy…

to be the least sustainable. Biomass can produce air pollution, damage ecosystems, and contribute to global warming emissions. Biomass can be produced in several different ways, it can be burned, fermented, digested by bacteria to produce methane gas for powering turbines or gasified, which is then burned. Biomass is mostly used in the United States, and has not proved to be better than fossil fuels, in terms of long term pollution reduction. An advantage of biomass is mostly to agriculture…
