The World Research Institute estimated that about ¾ of the worlds shallow reefs are threatened by climate change, pollution, and overfishing. All in which are man made influences that affect the ocean greatly. It is predicted that by the year 2050 90% of the coral reefs on earth will be dead or threatened. Not only that but soil erosion, algae growth from fertilizer runoff, increased UV exposure, and damage from fishing and diving are just adding to the problem. However, the
This is the opposite of the cellular respiration is as humans go through. The last key needed for photosynthesis is water. This part is more visible, mostly because the roots absorb water, which goes up plant stems and to the leaves. There are 2 stages of photosynthesis, which are the light reactions (the photo part of photosynthesis) and the Calvin cycle (the synthesis part). The light reactants produce convert solar energy to chemical energy.
Dead zones are oceanic areas where there is a depletion of oxygen levels and often have no living organisms. In fact, according to the National Oceanic and Atmospheric Administration (NOAA) “ The second largest dead zone in the world is located in the U.S., in the northern Gulf of Mexico” (US Department of Commerce, National O...). They are caused by pollutants such as oil and fertilizers which can cause an overgrowth of algae. The overgrowth of algae blocks sunlight from the plants underwater, disrupting the photosynthesis process. As a result, the food chain is disrupted because the producers at the bottom of the food chain cannot produce because sunlight is blocked, leading the primary consumers without a source of food.
Ocean acidification leads to a reduction in the amount of carbonate ions in the water. Many marine animals essential carbonate ions for the calcium carbonate essential to form skeletons and shells. This will disturb their development and ability to reproduce – ultimately threatening their populations.. Falling numbers of less well-known species, like pteropods – tiny swimming snails – have important effects further up the food chain. Pteropods are important sources of nutrition for many types of fish, whales and birds in polar and sub-polar regions.
Purpose: The purpose of this experiment is to see how long it takes for the 10 spinach leaf discs to undergo photosynthesis and thereby rise in the two solutions. Hypothesis: All of the leaf discs in the sodium bicarbonate solution should be floating before the discs in plain water because the bicarbonate is a carbon source that will allow photosynthesis to continue. Background: Light is absorbed by leaf pigments (chlorophyll) which makes electrons within a photosystem moved to a higher energy level. The leaves then make ATP, which reduces NADP to NADPH, and add CO2 into organic molecules. When the leaves go through the process of a light-dependent reaction by being placed in water, oxygen is created through photosynthesis and is released into the interior of the leaf.
This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem. Furthermore, another ecological hazard that this incredible animal faces is fishing and it’s equipment. According to the text, “Modern fishing methods have created some serious problems for the ocean. The populations of almost all fish species that we eat have shrunken,”(Dignan 14). This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold.
The topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
Ocean Pollution DBQ Did you know that every year, eight million metric tons of plastic is dumped or somehow ends up in the ocean (Doc. 1)? The following sentences will talk about what people are doing to pollute the oceans and how they are making the pollution better. Humans are the biggest threat to animals in the ocean because they litter so much (OI). Sometimes, people litter without even knowing they're littering.
One study from 2015 about the long-term effects of the oil spill in the Gulf of Mexico from the Canadian Journal of Fisheries and Aquatic Sciences, projects a loss of more than 22,000 jobs by 2020, as a result of the impacts to businesses that rely on heathy fisheries. This conclusion also leads to an upset in tourism and recreational activities. As suggested by the Third R&D Forum on high-density oil spills, "sunken heavy fuel oil may have significant impact on seabed resources and fishing and mariculture activities." Oil soaked sands and water often result in restrictions from swimming and boating in an area, thus giving people concerns that their heath may be compromised, deterring people from vacationing. Therefore, even hotel and restaurant businesses who make their income from recreational activities and scenery in the coastal
Ocean litter is on type of marine pollution, that enters the through several different ways, like ‘at-sea’ dumping by fishing, merchant, recreational ships and cruises. Organisms are affected by the ocean base litter. Animals like fish, sea birds and other marine animals can by trapped and tangled in the litter, or they can ingest little fragments, which they think is ‘food’ (Robe Litter Survey,________). Australians use 13-14 billion drink containers every year. Although recycling makes a difference, many container still end up in beaches and oceans.
