A food web consists of all food chains of an ecosystem. A food web is a diagram which shows the transfer of energy between species. Energy is transferred through food; therefore, food webs basically show which fauna eats which. Food webs are organized into layers of who eats who called trophic levels. The bottom trophic level of a food web is the producers, the second being the primary consumer, then the secondary consumers, tertiary consumers and the final trophic level being the decomposers. The ecosystem of the Great Barrier Reef is a fragile balance, with a food chain that has several points, in which each one is reliant on one another. The Great Barrier Reef’s coordinates are 18.2871° S, 147.6992° E. The Reef has a huge amount of flora
Isopods are crustacean, which is split into smaller groups, called order. Scientifically Isopoda order is called isopods, which include pill bugs and sow bugs (Crustacean class). Most of the time isopods are mistaken for “bugs” since they look like insects. Even though they are closely related to crustaceans, their bodies are particularly similar to crab and other sea creature with shells.
The purpose of this report is to investigate the impacts of urban development on biodiversity at stumers creek dog beach. This report will include data collected from the creek including; water samples, soil samples and animal and excrement surveys in order to determine the health of the environment.
Abstract – The study to prove that ecological succession occurred at Conrad’s beach took place at Conrad’s beach in Nova Scotia. Species richness, height and amount of organic material was sampled by using a 1m x 1m quadrat. As predicted the abundance and size of the organisms were larger further as the groups got further from the sand dunes.
Each ecosystem has their own biodiversity, differing themselves from other ecosystems. In our experiment we are revisiting how the intensity of light effects the movements of Gammarus setosus. From J. M. WeEsøawski, M. ZajaÎczkowski, J. Wiktor (1997) report, when there are Macrofauna taxa and Macrophytes, there would a frequent amount of Gammarus setosus. With this we can conclude that Gammarus setosus plays a large role in the food chain. By getting more information of the Gammarus setosus we able to get more information for future research into the how prey and predation with the Gammarus setosus. In addition, with more data the scientific community can make further conclusions and further prove the conclusion.
Chitons are a class of mollusc called Polyplacophora, when examined, share the same anatomical features as those of the first molluscs on earth. This means that they are t closely related to the beginning of the mollusc group. These molluscs vary in size but have the same features as a long, oval flat body with a segmented mantle to protect the ventral of the chiton. These organism have learned to create a “suction” affect using their ventral to hold on to rocks so that they do not get washed away by the waves. Their radula is a teeth like structure that scrapes of algae that are living on rocks. Chitons also have light sensitive receptors that will detect an amount of light that might be harmful to them and move slowly to the shade using their
Organisms grow, multiply, and adapt. It’s the way we learned and the reason as to how the Earth’s population continues to increase. It applies to all organisms: animals, plants, bacteria, and others. However, there are factors that restrict the numbers of population when it comes to multiplying. Predators, food
We went to the salt marsh at Wrightsville Beach, North Carolina. Starting at the water line we measured 100 meters into the salt marsh. At every 10 meters we stopped and laid a quadrat down, which is just a square made out of pipe. We counted the number of each species and organisms we saw in each quadrat and also measured the height of each plant. We repeated these steps until we got to the 100 meter mark, which took us eleven quadrats total. We also measured how far away from the shore it was at each quadrat. We took the elevation every ten meters. One person held the fiberglass staff and another person stood ten meters away and held the measuring pole. They moved their finger up on the pole until it was even with the horizon.
Convergent evolution can be defined as “the repeated evolution of similar traits in independent evolutionary lineages inhabiting similar environments” ( www.oxfordbibliographies.com/view/document/obo-9780199941728/obo-9780199941728-0038.xml) . It refers to the commonalities between two or more unrelated species, which arose as an outcome of adaptive evolution due to natural selection. Adaptive evolution is the changes
In 1921 Swedish scientist, Olaf Arrhenius proposed the Species Area Relationship (SAR). This theory was created to explain and understand the relationship between a size of an area and the number species therein, as the name suggests. It was concluded from the experiment that as the area increases the number of species found within increases continuously less. If graphed we notice a curve hence the species-area curve.

Beaches are coastal landforms that are constantly changing. They are the result of wave action by which waves move sand or other loose sediments and compact and settle in still water. Beach materials are the products of weathering and erosion of rocks offshore, coral reefs and of headlands. Sediments may also be river-borne through the process of coastal erosion. Once compacted, the accumulated sediments are more resistant to erosion. Vegetation establishes shortly after, and their roots will also help resist erosion by slowing the fluid flow at the surface layer.
Sandy beaches are important dynamic coastal systems that border most of the shores worldwide (Goncalves et al., 2008). On first glance, you would think that sandy beaches are barren, empty stretches of land. However, there is a large amount of marine life found on top of and within the sand. Sandy beaches are one of the most extensive intertidal systems worldwide, and the macrofauna of these habitats make up the greatest proportion of most open shores (Lercari et al., 2002). Ocean sandy beaches are environments in which physical structure can be defined in terms of three variables: sand grain size, wave climate, and tidal regime (McLachlan and Dorvlo, 2005). The following essay looks at the impact that wave action has on the sandy beach communities
Coral reefs are one of the most diverse and complex habitats. They are one of the most interesting and colorful ecosystems found in the marine environment. They are very unique in many different ways and a crucial support for human life. They play also a very important role in the marine life such as giving shelter and food for millions of species including fishes, crabs, or shrimps. They support 33% of marine fish species. They also have specific and certain conditions to be formed, and to survive. They are also known as the “rainforest of the oceans” because of its huge diversity. In this research paper we will explore more about coral reefs and their importance.
