Speed here is of essence and spices like flying fish are able to jump out of water to escape predators. Others that lack like jellies are transparent. Turtles will have a shell to protect them. Gills enable animals to manage different water pressures like the sharks while whales have the capability of holding their breaths for longer periods. On the other hand, since the benthic zone does not allow sunlight to reach it due to its depth (beyond 600 feet), some fish and crustaceans, at this level do not see, in fact half of the species at this level are blind. In this sense, the organisms have adapted to produce their own lights from their specialized parts in their bodies known as photophores. In addition, since there is lack of phytoplacton to start the food chain, life is limited and fish have adapted to fulfill their needs. For instance, some fish have large mouths or guts to enable them consume as much food as possible whenever it becomes available. Others like anger fish have special parts in their dorsal fin to attract prey (Svitil, n.d.).
Answer to question 5
The marine ecosystems as are exposed to human interference are definitely prone to different threats. Their effective conservation will all revolve around the appropriate control of natural resources to incorporate marine ecosystems. First considering threat to coral reefs, it or can result from ocean acidification which is a result of the increasing amounts of carbon dioxide in the atmosphere which in turn is absorbed by the ocean. For example, ocean absorbs approximately 525 billion tons of carbon dioxide (CO2). Despite ocean reducing CO2 levels over the globe, it has done so at the expense of marine life. The ocean PH has reduced due to the resulting reactions with CO2 hence unsuitable chemical composition for thriving of coral reefs. To...
Even with the fact that Ancient Greeks obviously had a limited understanding of winds, it is nonetheless intriguing to look at how they perceived conditions in which winds are more likely to occur. Wind speed is faster above the ground because it encounters less friction and winds move very fast when there is nothing to slow them down. This is why wind turbines are mounted on top of towers. Anemometers
The Santa Ana and Brush Fire Texts Linda Thomas’s “Brush Fire” is like the micro-perspective and Joan Didion’s “The Santa Ana” is like that macro-perspective when it comes to describing the late-fall winds and the fires that consume the region. Thomas tells of the brush and the irony of building in the path of the fires. Didion tells of the wind and the fire and the irony of living in a
Tornadoes in the United States Every state in the union has experienced them, and the destruction caused by tornadoes each year can climb into the billions of dollars. Scientists have learned a great deal about tornadoes over the past several decades, though, and warning systems are now able to prevent many of the casualties that tornadoes used to cause. To determine what has been learned and what steps have been taken
hurricanes Floyd and Grace both brought devastating damage, Floyd's impact came largely from the Floyd itself, while Grace's impact came from the combination with two other weather systems. By itself, Floyd was a force to be reckoned with: a Category 3 hurricane that stretched from Canada to the U.S. that came on the heels of Hurricane Dennis. In contrast, Grace was a less powerful storm that would have dissipated
Brown did not contact Michael Chertoff, Homeland Security Secretary, to activate emergency response workers until five hours after Hurricane Katrina made landfall (Mayer et al. 2008). Furthermore, Brown did not use any urgent language about how devastating Hurricane Katrina's effects might be along the Gulf Coast, a response which many have found to be sadly inadequate. Since the Katrina disaster, FEMA has been essentially stripped of its emergency powers, and
Figure 1. Golden Gate Bridge's Safety Net Source: http://www.zingarate.com/network/san-francisco/files/2012/11/safett_net.jpg The safety net was an essential risk management feature for the bridge project because the bridge needed to be 220 feet tall to accommodate commercial and naval vessels and falls from this height would certainly be fatal (Design and Construction 4). Unfortunately, this turned out to be the case during the final phases of construction. Despite this expensive security precaution, a catwalk collapsed
