Aquatic ecosystem

Coral reefs are one of the most diverse and valuable ecosystems on earth. According to the National Oceanic and Atmospheric Administration, coral reefs support more species per unit area than any other marine environment, making them the equivalent of an aquatic rain forest (Kitch and Edwards). Occupying a mere one percent of the seafaring environment, coral reefs are home to more than one quarter of all known marine species. This translates to approximately four thousand species of fish,…

The ecosystem has been changing rapidly and the fastest changes are taking now. It’s affected by overfishing because it’s a big part of our food source. Also affected by the distribution of species on Earth is becoming more homogeneous. This is caused by the extinction of species or loss of populations. Also the amount of water stored behind large dams is estimated to be three to six times the amount held by natural river channels this excludes natural lakes. Overfishing has started to become…

Pesticides can damage the DNA within an organism on a molecular level. It is because of this that Atrazine and Roundup, when polluting the aquatic environment, are able to affect the metabolism and reproduction of organisms. GMOs have the power to aid the environment, as well. For example, they provide means of resistance against multiple pesticides in the agro-ecosystem and increase growth rates in fish species and livestock, in addition to resulting in a tolerance build-up against herbicides…

Summary of the situation My project is about dolphins in captivity. Dolphins are being taken from their homes and families and put into small tanks and pools for people to look at and watch them perform tricks. Dolphins often swim over 100km a day but dolphins that are held in captivity don’t get nearly as much exercise. These dolphins are often bored and are either sitting at the bottom of the pool or floating at the top, but dolphins in the wild don’t usually rest and are very active.. When…

River otters can stay underwater for up to eight minutes and can close their ears and nostrils to keep water out! They can also dive to a depth of 60 feet!The otter is a small mammal that lives both in water and on land. There are 13 known species of otters that inhabit areas around the world Otters have a thick coat of fur which enables the otter to be warm in near freezing waters. There is also a series of thin hairs under the otters fur that help to trap air and keep the otter warm. The river…

the movie included several emotionally charged reactions: laugh-out-loud comedy, monkey’s swimming underwater and crocodile’s eating prey. I also earned that within our earth, the animals have to adapt in order to survive. The salmon, living in an aquatic environment, swim in groups upstream, which is behavioral adaptation; this is modifying a behavior in order to survive and reproduce. In addition, the salmon stay in a large population and when they swim, they provide energy transfer to the…

species aren’t native to Hawaii, coffee, macadamia, passion fruit, and pineapples do not pose a series threat to the native ecosystems of Hawaii, like the strawberry guava. Strawberry guava is an invasive alien species to Hawaii and can be managed through mechanical control, herbicide application, and biological control to prevent further dispersal and damage to the native ecosystems of Hawaii. Introduced to Hawaii…

are more likely to be killed by a bee sting than a shark! Sharks are demonized, But, they actually really help us and our environment. Gratitude, a great white shark, is tagged which helps ocearch track and protect her. Great whites are amazing, aquatic creatures, they have amazing features. First, they have great eyesight, they can see in the dark water! Which makes them able to hunt at night. Next, they have amazing smell and hearing senses. It’s believed that they can smell a single drop of…

Runoff can pick up chemicals, fertilizers, spilled gasoline, and other toxic substances from urban, suburban, or large rural areas, and deposit them into the water, which contaminates the water(Runoff, 2016). Human activity runoff affects marine ecosystems through this…

up short (Kreuter & De Rosa, 2004). The Great Lakes ecosystem is the largest body of freshwater in the world. This ecosystem holds 18% of the worlds freshwater supply in the world, it covers 95000 square miles of shoreline; includes 5000 tributaries and has an area of drainage of 288000 square miles. The Basin is populated with more than 35 million people and they depend on its natural resources to sustain their lives (Great Lakes Basin Ecosystem Team). The…
