Algae

would be less animals that live in the trees like birds. Also, they help make more berry bushes so that there is more food. The ecosystem would change dramatically if there were no more grizzly bears. Next, in the Data Nugget about coral bleaching the algae living coral is what makes coral the different…

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.…

bone. When algae which corals have are lost we can see bones through corals’ transparent tissue. Stresses cause coral bleaching ―high or low temperature of seawater, strong light, ultraviolet rays, low density of salt, and so on. They prevent algae from photosynthesizing and a surplus of sunlight energy injures algae more. The effect is dying of algae, and corals die too because they get nutrients from algae. Anyway, acanthasters are famous as natural enemies. Actually, they do not eat algae of…

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…

are not located by a ravine run off do not have the issue of sewage, or fertilizer run offs. 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…

of this experiment is to determine if algae will grow more if fertilizer is added to the water where the algae is growing. Background/ Introduction An algal bloom is an increase and accumulation of algae in freshwater or salt water systems. Most algae blooms are caused by blue-green algae. Blue-green algae is actually not algae at all, it is a cyanobacteria. A bloom can lead to a green, blue-greenish or reddish discoloration of the water, and if the algae bloom lasts long enough streaks or…

This is through a process of slow deposition and accumulation of limestone removed from seawater. Stony corals and coralline red algae grow among the coral colonies. Limestone is used for the outer part of coral polyps and hardening the fleshy parts of the coralline algae. After organisms die, they leave the limestone skeletons. The reef-building process is very slow, it takes decades to centuries. Coral reefs start to form when coral larvae attach…

plants, are water milfoil, hornwort, and water primrose. Floating plants, float on the surface of the pond. They do not need soil, as the extract their nutrients from the water. Floating plants are extremely beneficial as they control algae. Floating plants control algae by restricting light, and filtering out excess nutrients. Some examples of floating plants, are duckweed, and water…

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…
