Trophic level

marine invertebrate animals. These are smaller zooplankton but it is important for larger marine mammals as food for baleen whales, whale sharks, seals, and a few seabird species. Krill phylum is Arthropod. Krill form key trophic link between primary producer and higher level in marine food web worldwide. The size range of krill is about two inches (five centimeters) in length. Microorganism like diatoms etc when colonize on microplastic beads or nanoplastic then it fed the krill then…

obviously larger than the otters, were the consumer of the otters, the crocodiles are carnivores. We also viewed some producers, like some of the plants that the monkeys chewed on; producers transfer sunlight into food. The producer-consumer level is the trophic level. An example of this is when the carnivore eats the producer. In the East Africa river, a lot of the animals eat one another, which is a food web, a series of food…

2015) We must present clearly documented proof so people will have an urgency to make a change. This water needs to be consistently tested. Proving oxygen levels are decreasing, phytoplankton is being depleted by micro-plastics and nutrients being replaced with more toxic elements. We will do this by testing nutrient, chemical and oxygen levels in the Garbage Patch areas, as well as plankton and plastic…

in front of our faces. Convenient foods often contain wasteful plastic packaging that end up polluting the environment. Foods that contain meat, dairy, or eggs are our daily staple, but it requires more energy to produce these foods because of trophic level efficiency (Porter, 2003, pp.4-5). Thus, we end up wasting a lot of water, vegetables, and land to produce a beef patty when it would less…

Arctic Tundra Referred as “treeless plain”   Earth's coldest biome!  Earth's youngest biome! (formed 10,000 years ago) Located in the Northern Hemisphere (Alaska, Canada, and Siberia)   Known for its cold, desert like conditions Average Temperature (Winter): -34° C (-30° F)  Average Temperature (Summer): 3-12° C (37-54° F)  Arctic Tundra Wide variety of plants (1,700 kinds of plants)   Short growing season (50 – 60 Days)  Carbon Sink (Stored in permafrost) Animals…

The Great Barrier Reef Introduction: The Great Barrier Reef is the world's largest coral reef. (1) It consists of a nexus of coral reefs, shoals and islets in near the Northeastern coast of Australia. It extends in a northwest-southeast direction for around 1,250 miles (2,000 km), at an offshore distance ranging from 10 to 100 miles (16 to 160 km) and has an area of 135,000 square miles (350,000 square km) allowing it to be the largest coral reef in the world. It is sometimes referred to as…

carbon emissions throughout history. Since the Industrial Revolution during 19th century, the carbon dioxide level has been dramatically increasing. In addition, the CO2 concentration level has reached a constant of 280 ppm during Pre-Industrial and will reach 700ppm by the year of 2060 under the projections (Cooley). Figure 1 shows that as the carbon dioxide levels increase in ocean, the pH level decrease.…

for aquatic ecosystems, marine plankton allows the transfer of energy between different trophic levels in saltwater ecosystems (San Martin et al., 2006). Plankton plays a key role in oceanic changes as the primary biological sequestration of carbon out of the atmosphere into surface waters. Phytoplankton plays a huge role in the transfer of energy from solar energy to other organisms as the go up the trophic…

The view of the ocean since the middle of the 20th century had been one of hope and prosperity for feeding the growing human population. Many believed it to be an inexhaustible pool of food and resources, and so efforts to create newer, more efficient methods of obtaining these resources had sprung into action. Somewhere along that time and now that image changed to a giant trashcan for people to dispose of their sewage, chemicals, and garbage. Two consequences of this transition, mercury…

increasing CO2 levels only occurs with iron replete environment. (Fu,F., Mulholland..). The more carbon and nitrogen fixation increases with an increase in atmospheric CO2 the more iron that is used up, in particular by phytoplankton. Thus the bioavailability of iron may reduce due to OA. Models of diatoms for Atlantic surface water have displayed them taking up iron at a slower rate in response to OA but phytoplankton’s requirement of iron is unchanged with increasing CO2 levels. Therefore, it…
