1.) Three abiotic factors are energy, climate and weather. Three biotic factors are plants, animals and bacteria. 6.) Natural selection is the process that determines which individuals within a species will reproduce and pass their genes to the next generation. Genes that are advantageous are more likely to be passed on. Death is part of the process of natural selection, species which fail die. The number of offspring, pass on the beneficial genes to the organism. 13.) Parasitism, mutualism and…

begins in freshwater streams. Once they hatch from their eggs the young ammocoetes bury themselves in a U-shaped burrow in silty or sandy river bottoms (Mee-Mann). The ammocoete, however leave their heads out of their burrow in order to filter feed on algae and microscopic organisms in the stream. The lamprey young often will migrate at night by drifting on the current, and then re burrowing downstream (Mee-Mann). Ammocoetes will often grow up to five inches long in their burrows, and remain in…

Neither the story of Noah and the ark, nor Pi on the lifeboat with a tiger, can be considered objectively true, in all of their details. But both are metaphors that make comprehensible the passes-all-understanding phenomenon of human survival in extreme circumstances. Or as the Japanese investigators finally acknowledge in the summary report with which the novel concludes, Pi’s is “an outstanding story of courage and endurance in the face of extraordinary difficult and tragic circumstances”…

The nutrients that sea sponges expire feed other marine species, and in turn it is a food source for starfish. Sea snails consume algae and phytoplankton loosened by starfish on the ocean bottom, and are also a favored as food by starfish. Crab, lobster, starfish and jellyfish are all prey for larger predatory organisms, such as sharks, turtles, manatees, and ocotpus. Jellyfish eat…

The way that copper sulfate kills fungi and algae is it binds to the proteins, this damages the cells making them leak and die. The way copper sulfate kills snails is it harms the normal function of the skin cells and enzymes. Copper sulfate can be a liquid, crystal, or dust. If copper sulfate is…

The current problem in Jaffrey is that, recently Jaffrey residents have noticed that Jaffrey Lake, which used to be clean, and a great place to swim, has changed. Slimy, green algae floats on the surface, and the water has turned very dirty. People are finding dead fish on the shore, and everyone is afraid they'll get sick if they swim in the lake. This is a major problem because, people around the lake will slowly start getting sick and one day the all the fish and plants in this water will die…

Whale sharks don’t hunt their prey like other sharks, whale sharks are filter feeders, they consume food by engulfing their prey that enters their mouth. Like most filter feeders their diet consists of small organisms such as plankton, krill, shrimp, algae and larvae. The…

The focus of the documentary is on the destruction of the world’s coral reefs and the part that humans are playing within that destruction and the rebuilding of the reefs. The documentary mainly follows an English artist/sculptor call Jason Taylor and his work within the community of Cancun, Mexico to help rebuilt a coral reef there through the use of statues to create an artificial reef which benefits the local ecosystem greatly. The documentary has a particularly poignant message for the role…

More likely to expose and kill the bacteria than any other surface. “Shark skin itself is not an antimicrobial surface; rather it seems highly-adapted to resist attachment of living organisms such as algae and barnacles,” said Dr Mann. “Shark skin has a specific roughness and certain properties that determine organisms from attaching to the skin surface. We have learned much from nature in building this material texture for the future.” This can definitely…

Also, the saturation of the Emerald estates water sample was 47%, which is poor. The dissolved oxygen level is low because as decomposers metabolize the dead algae, more and more oxygen out of the water. If people would fish in Lake Carson there would most likely be little to no fish, because fish need oxygen and if there is little oxygen then the fish will die. Furthermore, if you look at Figures 16 you will…
