are a causative factor for the possible mass extinction of marine plants and animals (Galgani et al. 45). Oil spills, overfishing, and shipping activities are further causes of adverse effects experienced. Human activity has over the years resulted in drastic climatic changes. Pelagic Zone This refers to the open ocean which is further divided into smaller regions based on depth. The pelagic zone is able to sustain fish and plants but as it deepens, life can hardly be sustained (Whitehead et al.

Marine Biomes Shonda Morton October 20, 2013 SCI/230 Paula Roberts A marine biome is a large aquatic zone that takes up almost 75% of Earth’s surface, has a salt concentration around 3%, and is distinguished from other biomes by its physical environment. According to Campbell Essential Biology with Physiology, (2010), the habitats of a marine biome varies depending on the level of the sea that it exists (pp.382). The layers or “zones” that make up the marine biome

temperature. Organism require oxygen, and in water bodies, they get that oxygen in the form of dissolved oxygen. As the name implies, Dissolved oxygen (DO) is oxygen that has dissolved in water. Like plants and animals living on land, aquatic organisms and microorganisms also need oxygen to breathe. For aquatic organisms, they get their oxygen from dissolved oxygen. Therefore, it is important that there is enough dissolved oxygen in a water sample to ensure a healthy community. However, there are many

deciduous tree that can reach 50 feet; it is popular for its fragrant, pink flowers that remain throughout the winter months. The Mimosa was moved from China to the United States in 1745. The invasive plant was originally brought to places like Florida and other places in the Southeastern United States. The plant was brought to the United States as an “ornamental tree”, and for no other beneficial reason (Mimosa: Silk Tree). Throughout the years this species of trees has become invasive to much of the United

figure out this mystere. A way that the early mammals could have survived the execution is by hiding in burrows and aquatic environments. Now how this helped them is because the burrows and environments they lived in was able to block them from the heat from the impact. On the Article “Why did the mammals survived the ‘K/T extinction’ news.psu.edu it says “Underground burrows and aquatic environments protected small mammals from the brief but drastic rise in temperature.” This shows us one of the few

My aquatic invasive species is the water chestnut. Though it is not too common in Indiana waters, it is on the invasive species list, due to the prediction that it will quickly become a threat. It is an aquatic plant native to Eurasia. Currently, it is naturalized in North America and Australia. The states that it is most common in Connecticut, Delaware, Maine, and others on the eastern coast. The water chestnut or the "Trapas Natan" is a rosette of floating leaves usually rooted in mud near small

Top 10 Water Primrose Facts You Need to Know Water Primrose biologically referred to as Ludwigia spp. is a herbaceous plant native to Central and South America. It can be found mostly in the wet, swampy ditches that receive plenty sunshine. One can spot it in shallow lakes, ponds surface and slow-flowing streams. The plant is made of round, elliptical or egg-shaped leaves with margins. The leaves are shiny vibrant green on the upper surface while slightly hairy on the bottom side. They are alternately

nature expert talked about invasive species, seed distribution, and plants. When the water rises the seed pods come off of plants and float on the water, the seeds then are carried to new places. The 7th graders talked about how the monarchs are declining because of the lack of milkweed. They also talked about plants like goldenrod and poison ivy. Around the Portage River there are habitats like prairies, forests, and floodplains. Plants in the riparian zone help to filter the water before it goes into

The photosynthetic rates of Camomba Caroliniana, were effected by the color of light it was exposed to during the experiment. As seen in Table 1, Camomba Caroliniana that was exposed to green light had an average photosynthetic rate of 0.13 mL O2 produced/g/hour, which was lower than the photosynthetic rate of Camomba Caroliniana that was exposed to white light (0.19 mL O2 produced/g/hour). The data from table 1 can also be used to determined the reliability of the experiment, the standard errors

The hypothesis that red light would produce more dissolved oxygen was not supported by the results of the experiment. Without having more accurate data it is impossible to say which color light induced its plant to produce the most oxygen. The reason for not having more accurate data is because of the way of testing the dissolved oxygen. By testing with the dissolved oxygen tabs the data could not have been very specific and specific data is important for a good experiment. The way of getting much
