The Coral reef what a wonderful place The Coral Reef, where all the fishies plaaaaay
Over Fishing Convict tangs help eat the algae so that photosynthesis will be able to get through, But what happens when people over fish the convict fish and they cannot eat the algae making it hard for the coral to go under photosynthesis because the algae, It also depleats the food source.
When the toursits are scuba diving they are breaking the coral. Therefore the coral does not grow back. And the coral will never grow back
Logging run off
when people cut the trees, and the mud and sedaments from the tree are being washed off by the rain it runs off into the rivers or lakes , or any type of water way available. These water ways lead into the ocean and into the corals which block off photosynthesis from occuring and the corals get bleached
Burning Of Fossil Fuels a fossil fuel is a hydro carbon it seperates and the carbon goies up into the air and cnd combines with oxygen the CO2 makes acid rain which reduces th acidity of the ocean it makes the ocean more acidic and kills the coral
Coral reefs benefit a healthy world by providing:
Habitat: Home to more than 1 million diverse aquatic species, including thousands of fish species
Income: Billions of dollars and millions of jobs in more than 100 countries around the world
Food: For commercial fishing enterprises and for people living near coral reefs, especially on small islands
Protection: A natural barrier protecting coastal cities, communities, and beaches
Medicine: Potential treatments for many of the world’s most prevalent and dangerous illnesses and diseases
Ah look the Abyss. The deepes part of the ocean, where only the smart and strong oragisims can survive with the hard pressures and darkness
Bioluminescence is the production and emission of light by a living organism.
The angler gets its name from the elongated dorsal spine that supports a light-producing organ known as a photophore. Through a chemical process known as bioluminescence, this photophore can produce a blue-green light similar to that of a firefly on land. The fish uses this appendage like a fishing lure, waving it back and forth to attract its prey.
Its skin is specially adapted to reflect blue light. Since nearly all light emitted from bioluminescent creatures is blue, the anglerfish can be nearly invisible to other deep sea animals.The sharp teeth of the angler are angled inwards, which helps to prevent the prey from escaping. The anglerfish can extend both its jaw and its stomach to an incredible size, allowing it to swallow prey twice the size of its entire body. Since food can be scarce in the deep sea, this special adaptation allows it to stock up on food during times of plenty.
1. what did you read what did you learn : I read about the coral reef and how we as people in this world are destroying it. I also read about over population and how we might run out of food by the year 2050. And also some articles about how some chemicals have gone into the river and are killing the fish.
2. Raritan River- I learned that the Raritan River is in our county, I also learned that the river is very toxic and we have polluted it. It is also home to our fish which we tend to kill off because its so polluted. Also there are super funds that are not so super fun, and they don’t really do much to help the Raritan River.
3. Coral Reef- I learned that the coral reef is basically the basic food source in the food chain. small plankton organisms rely on the coral reef to survive. As in other animals rely on the plankton to survive. Its all basically a food chain.
1. Ecological problems: 1.large increase in the population of the Nile perch. This huge predatory fish will reduce or eliminate many defenseless native fish species. It puts small-scale fishers ad fish vendors out of business, and local forests were depleted for firewood because of the perch’s oily flesh that must be preserved by smoking. 2. lake began experienceng alfal blooms because of nutrient runoff from surrounding farms, deforested land, untreated sewage, and declines in the populations of the algae eating cichlids. 3. The nutrient-rich lake has been invaded by the water hyacinth. 4. Nile perch population is decreasing because it severely reduced its own food supply of smaller fishes.
2. 1. greatest marine biodiversity occurs in coral reefs, estuaries, and the deep ocean floor. 2. biodiversity is higher near coasts than in the open sea because of the greater variety of producers and habitats in coastal areas. 2. Biodiversity is higher in the bottom region of the ocean than in the surface region.
3. It helps us stay alive and it helps support our economies, marine systems provide important ecological and economical service activities.
4. Habitat loss and degradation, the greatest threat to the biodiversity of the worlds oceans and freshwater system..Dams currently hold three to six times the amount that flows into natural rivers and humans take twice as much water from each year from rivers and lakes. This destroys aquatic habitats and water flows and disrupts freshwater diversity.Population growth and overfishing are other problems which harm aquatic zones.
6. the coastal population growth will add to the intense pressure on the worlds coastal zones. in 2004, the UNEP estimated that 80% of the oceans pollution comes from land-based coastal activities. So humans have doubled the flow of nitrogen, mostly from nitrate fertilizers, into the oceans since 1860, and the 2005 Millennium Ecosystem Assessment estiates this flow will increase by another two-thirds by 2050
7. Overfishing has affected the populations of many marine and freshwater aquatic species, because when they over fish the fish cant reproduced fast enough
11. Four Factors that threaten the florida Manatee are that they usually die from habitat loss, cold weather, getting caught in fishing lines and nets, and when they’re slashed by propellers.
12. Toothed whales bite and chew their food and feed mostly on squid,octopus, and other marine animals.Toothed whales include Sperm whale and squid, Killer Whale, Narwhal, and a Bottlenose dolphin. Baleen whales use plates made of baleen, or whalebone that hang down from their upper jaw filter plankton from the seawater,especially tiny shrimplike krill. Baleen Whales include Blue,gray,humpback,and finback whales.
16. a. The traditional approach to the estimation and management of fish populations is called maximum sustained yield, and it is used to project the maximum number of fish that can be harvested annually from a fish stock without causing population drop.
16. b. In recent years, some fishery biologists and managers have begun using the optimum sustained yield. It attempts to take into account interactions with other species and to provide more room for error.
16. c. Another approach is multispecies management of a number of interacting species ,
18.Describe the regulation of fish harvests through comanagement.
19.Describe the status of wetland protection in the United States and list six ways to improve wetlands protection.
20.Describe the ecological and water supply problems of south Florida’s Everglades and efforts to deal with these problems. 21. The Quagga Mussel,sea lamprey,larvae of zebra mussel, and the Asian corp, that all invaded the Great Lakes, are very destructive and cost Canada and the United States millions of dollars .
22. The effort that has been made is the $3 billion that has been spent to help save the salmon although it hasn’t been effective.
- People predict that the next world war would break out because the over population of people would be fighting for water and aquatic wildlife in order to supply and feed off of
-Pakistan basically added water to their long list dispute with India , and the Indian natives are becoming wary because what they say are Chinese efforts to dam the Brahmaputra River.
-The water and food supply is becoming scarce so only the strong will survive
- China has the one-child policy law
- Scientist that were originally involved in this were Paul and Anne Ehrilch, and also Herman Daly
- This is effecting the aquatic habitats and environment because people are taking more water and the fish from the sea, which could effect food chains. Also there would not be so many fish left and the ocean would mainly become dead zones due to the massive amount of pollution that would occur with more people.
