Nearly 50 percent of right whale deaths are anthropogenic in nature. which of the following is an example of a carbon sink? Marine life, or sea life or ocean life, is the plants, animals and other organisms that live in the salt water of the sea or ocean, or the brackish water of coastal estuaries.At a fundamental level, marine life affects the nature of the planet. Down in the ocean depths, lots of nutrients are available for the phytoplankton, but without sunlight, they can't grow. most deserts are at 30 degrees north and 30 degrees south because humidity is lower at 30 degrees. D)Boreal forests have larger dominant plant growth forms than tundras, Phytoplankton are most abundant in the upper few hundred feet of most bodies of water because, C)Sunlight does not penetrate to great depths in the water. phytoplankton are most abundant in the upper few hundred feet of most bodies of water because: sunlight does not penetrate to great depths in water most deserts are at 30 degrees north and 30 degrees south because humidity is lower at 30 degrees. Which environment is most likely to be characterized by dry scrub with frequent fires? Common types of phytoplankton in the Great Lakes include: Diatoms; Green algae Some phytoplankton are bacteria, some are protists, and most are single-celled plants. 19. Phytoplankton culturing. The biggest impact was seen a few hundred feet deep in the water column, at the point where phytoplankton have enough light from above to still grow, and are receiving the most â¦ species into coda. answer choices ... low, but the large expanse of the oceans supports enormous numbers of producers such as phytoplankton. Why are phytoplankton most abundant in the upper few hundred feet of most bodies of water that is the depth to which sunlight can penetrate Earth's deserts are mostly 30 degrees north and 30 degrees south latitudes where humaidity is lower. The holoplanktonic species spend their entire lives in the pelagic environment; meroplanktonic forms are temporary members of the plankton, and include the eggs and larval stages of many benthic invertebrates and fish. It is also known by the name of microalgae, is similar to terrestrial plants which contain chlorophyll and require sunlight to live and grow properly. But a few hundred feet down below, the water is icy cold. Which statement about tundras and boreal forests is correct? Phytoplankton is the basis of different food webs that survive in water. To ensure the best experience, please update your browser. The marine zooplankton community includes many different species of animals, ranging in size from microscopic protozoans to animals of several metres in dimension. The table below shows measurements of the beak size of a sample of ten ground finches on each of 2 islands in the Galapagos archipelago. Many species, including some whales and birds, will travel thousands of kilometers during annual migrations. public housing priority for families with more than two children. 20) Which one of the following is fixed from the atmosphere by the bacteria? Other than showing which organisms are consumed by other organisms, describe what is indicated by the direction of the arrows in the diagram. which of the following annual population growth rates is paired with the correct doubling time. Given that beak size is generally determined, which of the following hypotheses is the most likely explanation for the difference in data between the islands? 10) Which is produced during photosynthesis? 1. Like land vegetation, phytoplankton uses carbon dioxide, releases oxygen, and converts minerals to a form animals can use. of stratification of the upper 100 m. The relative ability of flagellates and diatoms to react to varying growth conditions, in turn dependent on hydrography, is discussed. The two islands are about ten kilometers apart, and all the birds are the same species. Before construction begins, what experimental data should the student collect in order to eventually test the hypothesis? AND • Increasing absorption of the sun's energy warms the water surface further, which leads to further ice melt (completes positive feedback loop). (ii) Krill is the primary consumer in this food web (iii) The secondary consumers are Arctic Cod and Ringed Seal. . 5) The terrestrial biomes shown in the diagram vary in net primary productivity. india has a higher population growth rate than china and australia have. which latitude shown on the diagram above experiences 24 hours of daylight on december 21. which of the following statements is consistent with the graphs above? Raven, S.C. Maberly, in Encyclopedia of Inland Waters, 2009. The North Atlantic right whale migrates between subtropical and polar water annually. The word "trophy" refers tothe rate of â¦ Derived from the Greek words phyto (plant) and plankton (made to wander or drift), phytoplankton are microscopic organisms that live in watery environments, both salty and fresh.. Phytoplankton are most abundant in the upper few hundred feet of most bodies of water because. Ringed seals, the preferred prey of polar bears, come to holes in the summer to breathe. (i)The primary producer in this food web is phytoplankton. the best explanation for the lower humidity is that: warm air rises at the equator, cools, and sinks at 30 degrees latitude. 21) The zone that has the highest biodiversity, Open oceans produce the largest share of Earth's biomass because of the net primary productivity (NPP) of the oceans is, Low, but the large expanse of the oceans support enormous numbers of producers such as phytoplankton. Construction of a solar power plant is proposed for a desert area near a school. The current is driven by the prevailing south easterly trade winds. Which biome provides ecosystem services that include reducing the severity of floods and filtering pollutants from the water? Primary production representsthe synthesis of organic matter of aquatic systems and the totalprocess, photosynthesis, whose complex metabolic pathway can beoversimplified as follows: light + 6CO2 + 6H2O ----> C6H12O6 + 6O2 Plants have photosynthetic pigments, one of which, cholorophyllais present in almost all photosynthetic organisms. In the upper 100 m of the water column, their relative contribution remained approximately 1% until the onset of stratification, and persisted at 0.5â1% between 80 and 120 m throughout the summer. Iii Identify a secondary consumer. low, but the individual producers found there are huge in size. c. They can most readily hide from predators there. Describe one strategy that could reasonably be implemented to decrease right whale deaths caused by the commercial activity you described in part ii. E)The direct sunlight received by the creosote bush in the desert area during a 12 month period. The microscopic phytoplankton are suspended in the seawater. In this way, the oceans act as a sink of global carbon. 3.The cultured phytoplankton genera were chosen based on the most abundant taxa in the phytoplankton database of the Finnish Environment Institute (SYKE).
