hypothesis was accepted. This was determined by counting the number of oxygen bubbles produced by the plant in three minute time periods‚ while placing the plant at three separate distances from the light source. The data that was recorded supports the hypothesis by showing that as the aquatic plant moved closer to the heat lamp‚ the rate of bubbles per minute

been a sharp decrease of aquatic life such as fish and other aquatic creatures due to waste in the ocean. In addition‚ the chemicals released into the atmosphere from factories and hazardous waste had caused acid rain. Acid rain is deleterious to many aquatic animals. Unfortunately‚ it raises the acidity level in the ocean which is responsible for the death of many aquatic

Professor Susann Brown 10/5/14 Freshwater Ecosystem An ecosystem is an environment filled with living plants‚ organisms‚ and animals. There are for main components in an ecosystem. The relationship of these four components makes it possible for each component to pass energy and use the food chain to survive and flourish. Elements and compounds are basically a required food source for plants. Plants utilize the sun and photosynthesis to harness energy and are the primary producers of new energy into

soil and this would have reduced the carbon in the runoff (Wetzel‚ 2001). The terrestrial plants form much of the organic matter‚ the organic carbon in plant tissue is transformed by microbial utilization and degradation both at the site of growth and during transportation of runoff (Wetzel‚ 2001).The highest percentage of carbon is at the bottom of the sediment can be because there was more terrestrial plants and less urban development at that

water increase the amount of algae which reduces the amount of oxygen from the water column which is called eutrophication and cause the suffocation of fish and other aquatic organisms. The amount of waste particles suspended in water reduce the amount of sunlight received into the water which disrupts the growth of photosynthetic plants and microorganisms which affects the rest of the marine life who depend on the microorganisms. Industries are not the only culprits for water pollution. Unfortunately

fen‚ I believe that the “bog” is indeed a bog. Based off of United States Fish and Wildlife standardized wetland characteristics and the Aquatic Ecology class’s observations and data collections there is enough evidence to suggest that the Western portion of Dead Man’s Lake is a bog. In class we learned that bogs are ombrotrophic systems that are composed of plants that are able to grow with little nutrients such as

the only known planet that has conditions suitable enough for living organisms to grow‚ reproduce and survive. These conditions are a combination of non-living components like water‚ sunlight‚ temperature and living components like micro-organisms‚ plants and animals. The non-living components of a particular environment that make the conditions ideal for sustenance of life are known as the abiotic factors. Some of the important abiotic factors that affect living organisms are: Water Water can

• Duckweed (Lemna minor) is a member of the Lemnaceae family (Monette et al. 2006) it is a small plant that floats on the surface of still or stagnant water that is usually rich in nutrients (Keddy 2010). It was seen that Duckweed thrived in areas of high nutrient content‚ high sunlight and warmer temperatures (Taylor 2011) .It was also seen that fertilisers contained nutrients‚ such as nitrates‚ which greatly influences duckweed growth. Duckweed is also used for feed for farm animal‚ such as ducks

For aquatic environments the water and minerals are obtained and absorbed through the surface of the plants whereas for terrestrial plants the minerals and water they need is obtained through the root

Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? In my own opinion No but as u read more about it some things need to be preserved. For instance animals help the crops of the foods that we eat. Snakes help to cure different diseases. Humans help the plants and animals to grow. The fact that human beings are a species means that they depend on many other species that
