The effects of snails and elodea in water on carbon dioxide levels problem: how does varying the type of organism (plant or animal) in the level affect the level of carbon dioxide. The effects of snails and elodea in water essay sample background: this lab is used to test the effect the respiration rates in plants in animals and how it affects the level of carbon dioxide present in the water. The effects of snail hervivory on interspecific relationship between two aquatic macrophytes, elodea nuttallii and vallisneria spiralis were investigated using a 2 × 2 factorial experiment design.

Carbon cycle (virtual lab with elodea snails -- students design and run lab). Elodea (elodea canadensis) is a common plant that grows in fresh water ponds, lakes, and is often used in freshwater aquariums remember that plant cells contain both a cell membrane and a cell wall.

Experimental design: elodea, snails, water and btb will be placed in test tubes (some will be exposed to light and some will not be exposed to light) in the end, we hope to see a change in the color of the btb (an indicator) which is reflective of ph. Snails, a heterotroph, can only have cellular respiration in light or darkness if the elodea had been in the dark, photosynthesis could not occur, yet cellular respiration could, since plants can have it and it can happen in darkness. Unformatted text preview: explain how carbon dioxide cycles in aquarium water through snails and elodea hypothesis: the elodea uses 002 to make food, and it feeds consumers and the minerals from decomposing the organisms feed the elodea back again my hypothesis: the elodea uses (302 to make food, and it feeds consumers and the minerals from decomposing the organisms feed the elodea back again dependent variable the level of co2 in the test tubes is your dependent variable. Snails released an average of effects of snail grazing and nutrient release on growth of the macrophytes ceratophyllum demersum and elodea canadensis and the filamentous green alga cladophora sp | springerlink.
elodea & photosynthesis photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. The effects of fishes on plants or trees gain access to the water roach and rudd prefer elodea over potamogeton, . In photosynthesis, water, carbon dioxide, and sunlight is used to form glucose and oxygen cellular respiration is the opposite of photosynthesis the effects of the forest fire significantly decreased the rate of photosynthesis and increased the carbon dioxide in both georgia and florida.
The effects of snails and elodea in water essay
What are the causes and effects of “thermal pollution” on our environment article shared by many industrial processes are aggravating the problem of thermal pollution by discharging heat (in the form of hot water, air or effluent) into the environment. Elodea is a fast growing aquatic plant, it has a high photosynthetic rate and it leaves entirely under water but it can even continue to grow unrooted, as floating fragments elodea often overwinters as an evergreen plant in mild climates (like new zealand). Photosynthesis is the process of making food (usually in the form of glucose) from carbon dioxide and water in the presence of light this complex process of changing light energy into chemical energy takes place in green plants – plants hat contain chlorophyll.
- To test the light intensity, an elodea submerged in a beaker was placed at different measurement away from the plant, to see if oxygen (bubbles) is produced to test the availability of nutrients, different molarities of sodium bicarbonate was diluted in 500 ml of water with elodea, to see if rate of photosynthesis increased or decreased.
- Directly on the water surface in elodea nuttallii elodea canadensis, hydrocharitaceae in a paper on the effect of sub-.
- Students will explore photosynthesis and cellular respiration elodea snail virtual lab document effects it would have on people.
As the environment becomes more acidic, the elodea samples' volume of oxygen release decreases the average volume of oxygen release for the elodea samples in the control water group is 057 ml, 029 ml for the ph 40 group, and 015 for the ph 35 group.
