Aquatic animal

ecological components that included behaviour, condition, habitat use, energy intake and inter/intra specific interactions, etc. Accurate description of fish diets and feeding habits also provides the basis for understanding trophic interactions in aquatic food webs. Conceptually, trophic relations of fishes begin with foods and feeding behaviour of individuals or species. Diet composition analysis can be used to evaluate effects of ontogeny, or the establishment of exotic species (Gelwick &…

Another test that was performed was for Dissolved Oxygen, or D.O.. When testing for D.O., measures how much oxygen is in the water that is broken down throughout the water molecules. The fish and other organisms living in the water need dissolved oxygen to survive, except for plants, because plants produce the oxygen in the environment. The dissolved oxygen varies inversely to the temperature of the water. If the dissolved oxygen is low, the water will be too warm and many organisms living in…

510 × 335 Caption A lily pad is the leaf of the water lily plant. Alternate Text Group If you’ve ever encountered a body of water populated with lily pads, you’ve likely been amazed at how these unusual aquatic plants seem to float on top of the water. Lily pads are just one part of a larger pond plant that thrives in shallow lakes and ponds. Although these plants appear to be floating with ease, there is actually a lot going on beneath the placid surface. Even some of the most common facts…

In Rio the housing is cramped and are kind of slanted on a hill. They are usually 1 or 2 stories tall. Most of the housing in Rio is poorly made. Some houses are even falling apart. So housing in Rio is pretty bad. Rios transportation is quite good. There top 3 ways of transportation is buses, trains, and taxis. They have a lot of subways all over the place. Trains and subways are the main source of transportation. The trains are powered off of electric energy. Energy in Rio is 82% hydroelectric…

Environmental parameters Vs Plankton Incidents: The graphs presented in figureX to figureX, environmental parameters observed at different sites in each area are presented area wise along with the harmful plankton incidents observed. Average temperature, dissolved oxygen and salinity observed each day at each farm site is used to plot these graphs. There has been a notion that with drop in salinity, which means freshwater run off, there would be increase in nutrients and supporting higher…

Proposal Background Duckweed also know as Lemna by her genus is a small plant, that is mostly found in sub-polar and tropics regions in ditches, ponds, lakes and slow flow-flowing rivers. Duckweed have the main function of remove waste of water, however the main problem is that grows fast (Moss et al.2012). Research Question Is the use of different concentrations of phosphates will affect the duckweed? Hypothesis The more phosphate use the more the plant will be affected. Aim To…

Nitrogen and phosphorus are the major limiting nutrient elements in a variety of aquatic ecosystems and are altered by anthropogenic activities; such as row crops, feed lots, and humans (Elser et al. 2007). Larger inputs of nitrogen cause an abundance of phytoplankton and macrophyte production (Ferree and Shannon 2001).The purpose of this study was to examine nitrogen and phosphorus levels at Ada Hayden Lake in the comparative context of their effect on phytoplankton abundance as well as…

Duckweeds, or water lens, are flowering aquatic plants which float on or just beneath the surface of still or slow-moving bodies of fresh water and wetlands. Duckweeds are good for experiments because they are very simple plants, lacking a stem. Duckweeds are commonly found in environments that are associated with fertile, even eutrophic conditions. Since duckweeds can provide nitrate removal and can absorb mineral nutrients such as nitrogen and phosphorus, they are known for purifying water.…

Lake Tahoe is located in the Sierra Nevada mountain range in the northeastern part of California, boarding Nevada. It is well known as a tourist attraction for its great depth and clear cobalt blue waters located at high elevation. The combination of its depth, low ratio of watersheds to lake surface area, and its granite rock geology has lead to the creation of a low fertile and high transparent monomictic lake. Its also unique in that it doesn’t fully mix from top to bottom every year, lake…

marine habitat for the whale. Also, the human race can make an effort to reduce pollution and its impact upon marine life. If the human race were to significantly reduce pollution into the aquatic environment we could not only promote and provide a more natural and sustainable ecosystem for the whales but for all aquatic species that inhabit the ocean. Climate change will continue to be an augmenting issue that will…
