    Environmental Changes Affecting Organisms The world's climates is being affected by our way of life. Many of these changes aren't just hurting the plants and animals indigenous to these climates, it is also hurting us. Freshwater lakes and ponds, the Arctic ice caps, and humans are being affected by what is going on in the world. Many of the organisms in these freshwater lakes and ponds respond to the changes in their climate in two ways. They either can not respond, therefore, the number of…

    temperature and if the temperature increase then the zooxanthellae leaves their tissues making the coral unable to produce food on it's own, thus killing it. (5) If the temperature drops then a symbiotic algae present in the coral that helps it to get food lowers the amount of carbon transfer from the algae to the coral thus killing the coral.…

    One type of sediment to note is diatomaceous earth, an uplifted siliceous ooze which contains the remains of the microscopic algae known as diatoms (Garrison and Ellis 152). With a density lower than most other sediments—measured at 0.2816 g/ml in our lab results—the powdery and apparently sticky sediment has rather tiny grains as expected from this sort of sediment. As diatomaceous earth derives from the diatom ooze of the deep ocean floor, it originates from the slow dissolution of diatom…

    Algae, a form of biomass, help lakes, but they do need the right environment with the correct pH and different light conditions in order to aid the lake’s health. Algae use sunlight to make food for themselves and give themselves energy through the process known as photosynthesis by using chlorophyll. They also absorbs carbon dioxide, turning it into energy, which would take place more in the nighttime when it’s dark. In this longer-term experiment, I will be evaluating the sun or lack of sun’s…

    Pattern, Problem, Correlation: Algae are very extensive, and have proven to be very beneficial to our environment. They are a “diverse group of predominantly aquatic organisms that account for almost 50% of the photosynthesis that takes place on Earth” (Moroney et al. 2009). Due to this prevalence of algae, it is important to know its uses. Firstly, “algae are proposed to play a role in the global carbon cycle by helping remove excess carbon dioxide from the environment” (Moroney et al. 2009).…

    Their skeleton is made out of calcium carbonate protecting them from future encounters with predators. Many more coral polyps then can attach themselves to the coral already there and develops lots of coral reefs grouped together. Photosynthetic algae called zooxanthellae live in the coral’s tissues, protecting them from diseases and providing compounds they need for photosynthesis. Most people may not…

    increased and now plays a big role in fish kills. This happens when inordinate amount of fertilizers flow down the rivers and streams and into the sea, which in turn encourages algae and most, if not all, aquatic plants to overgrow. Fishes will then suffocate due to lack of oxygen and sunlight excessively consumed by algae and aquatic plants. According to Dodds et al, cyanobacteria blooms, contaminated supplies of drinking water, and hypoxia are the known consequences of eutrophication.…

So while their effects are minimized, in the Great Barrier Reef it can be seen that a reduction in herbivorous fish can still lead to increases in cover of algae, even if there is zero change in nutrient availability. This indicates that increased nutrients…
