Principal component analysis

Since producers won’t be able to make food, the consumers won’t be able to eat, and then decomposers won’t have anything to decompose and break down. The cycling in the ecosystems will eventually not happen so the ecosystem will fall apart. Other trees that have already grown are blocking the sunlight from reaching the sprouts. In other words many sprouts are competing for the sparse amount of sunlight. The sprouts may also be competing for water and other ingredients necessary to grow.…

Ningaloo Reef Marine Ecosystem 1. Identify ten organisms from your chosen ecosystem and draw a food web to show trophic interactions between them. Within this food web, you must include and label a decomposer. Ten organisms that live in the Ningaloo Reef include the bottlenose dolphin, loggerhead turtle, tiger shark, whale shark, Southern Calamari squid, jellyfish, zooplankton, dugong, phytoplankton and seagrass. The decomposer in this food web is bacteria, which works to further break down…

Recruitment of Organisms in the Galveston Ship Channel Abstract A study was done in the Galveston Ship Channel to see the recruitment of sessile or fouling organisms to a substrate. A total of six organisms were found. They were Barnacles, Serpulid Worms, Bryozoan, Limpets, Tunicates, and Amphipods. Recruitment structures were created by the students and were put into the Galveston Ship Channel and left for five weeks to allow adequate time for organisms to adhere to it. A full mesh cage was…

Purpose: Observe a compound light microscope to learn the names of its major parts. Research: Microscope is an essential tool for the study of small structures such as cells. The most common type of microscope is the bright-field microscope, used for this purpose is the compound light microscope, it is called compound because it uses two sets of lenses the objective and the ocular. The ocular lens usually magnifies 10x.…

1. Inquiry, inquiry based learning, is when simple observations turn into a curious question like “Why does it do that?” “Why does it change colors?” “What makes it move?”. Then that simple observation will catalyze an experiment, causing the individual to make a discovery proving that their idea is right or wrong. They will learn through trial and error, they will be able to grasp why something is the way it is or why that happens. 2. An example of a guided inquiry project I could facilitate…

important roles in the savanna and help biotic factors live. Fire as we know burns and destroys many things. Although this is true it actually helps renew and change the savanna so that it doesn’t become a tropical forest. The soil also is a big component because without soil there would not be plants and without plants the animals would not be able to survive. These 2 abiotic factors, although, they are small they definitely have a great impact on the…

and the sample was re-analyzed with the fluorometer. Pure chlorophyll a was used to find sensitivity calibration factors in order to calculate the concentration of chlorophyll a in the filter samples based on EPA Method for In Vitro Chlorophyll a analysis by Fluorescence (Arar, E.J. and Collins, G.B.,…

This study examined the effects of physical factors on diversity in freshwater environments by observing invertebrate diversity in riffles and pools in a freshwater stream. It was hypothesized that differences in invertebrate diversity between riffles and pools would be due to physical factors in the environment. To test this hypothesis, invertebrates were collected from each environment and classified by their taxa, and Shannon-Simpson indices were produced from these data to analyze the…

Barnacles are small crustaceans with hard shells made of chitin containing a small soft creature. This shell is a structural adaptation that helps them survive because it protects them from predation and other harms such as being crushed. (Anthoni, 2007) They filter water with their legs when they are submerged to eat plankton. When the tide goes down again, they close a ‘door’ in their shells to trap water inside. (Whoi education, 2014) This is another structural adaptation that stops them from…

Shark culling is a state government implemented policy in which sharks within the vicinity of a beach can be legally killed through shark nets or drumlines or a combination of the two. Drumlines are unmanned buoyant drums anchored one kilometre of a beach's shoreline. In between the drums are ropes with hooks. Drumlines are baited so that if a shark is swimming in the vicinity of a beach it would be attracted to the bait and not humans. Each state has different policies on drumlines depending on…
