Aquatic Plants Survive Better By Themselves Or With The Presence Of Fish?

      The general characteristics of the plants in these bodies of water have strong and steady roots, or roots that are bendable, depending on how fast the current of the water is. These traits help the plants mainly so they do not get swept away. Plants that

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

6. Describe several adaptations that enable plants to reduce water loss from their leaves. Include both structural and physiological adaptations.

Underwater grasses, or Elodea, was observed as well. This wide variety of life is a good indicator of the water’s health.

Adaptations in terrestrial environments involve the structural and functional qualities of the organism, to achieve the adequate intake of oxygen and other essential substances for the animal to survive, the evolution of more complex anatomical structures were required. Gravity is stronger on land than water, which means terrestrial organisms have to be more structural than aquatic organisms. Also, the balance of gas exchange with water loss is a key feature to survive in land. For example plants, when doing photosynthesis require carbon dioxide and water to produce oxygen, at the end of this process a lot of water is lost and terrestrial plants have to compensate the water being lost and the water taken from soil. Furthermore, the dispersal of gametes by wind or other animals have helped plants reproduce in large amounts and create varieties of species of the same kind. Short-term weather patterns as well as long-term climate conditions based on precipitations, temperature, wind, humidity as well as other factors are survival obstacles that organisms in land have to adapt to live; endothermic organisms have to maintain a constant internal

1. Based on the information in Table 2, it seems that the more dissolved oxygen in the water there is the higher the population of fish is.

-The more dissolved oxygen in the water, the more fish is observed in that area of water.

As a group, we did an experiment of billbug and what kind of water they enjoy to stay. Our team was used for experiment sugar water, salt water and plain water. We measured the material we wanted to use. We used salt for 2.0 g. We used sugar for 2.0 g. and we used plain water for 10 ml. We mixed 10 ml of plain water into 2.0 g of sugar and 10ml plain water into 2.0 g of salt. We placed one tissue for each chamber. We dropped in chamber one the salt water. We dropped chamber two the sugar water. We dropped chamber three the plain water. In the middle of the chambers we placed filter paper. Then we put 5 billbugs and let them free to move anywhere they wanted. After 5 minutes we recorded how many billbugs are on each side of the chamber. We

　　A Salt Marsh is an extremely important ecosystem. It is home to a variety of both plants and animals. Salt Marshes have distinct characteristic that separate them from other ecosystems. These characteristics force any plant or animal living there to have ways to adapt to the sometimes extreme environments in order to survive and thrive. Salt Marshes are not only biologically important, they also have economic and physical importance. We found many different plants and organisms while exploring the Salt Marsh on the Salem State campus. Salt Marshes contain great biodiversity, while functioning as sources of biological, physical, and economic importance.

The Eurasian Watermilfoil or Myriophyllum spicatum is native to Europe, Asia, and North Africa1. It came to the U.S, New England circa 1880-1940 and most likely came over seas by the aquarium trade or when people were traveling by ship1. It was first found in Maine in 2003 in a small body of water3. This species can be found pretty much all over the U.S but specifically it is found in wet marshy areas2. The Eurasian Watermilfoil is an aquatic plant and is devastating to the ecosystem. This plant spreads by creating fruits with nuts that can get eaten by animals and by having the nuts just fall from the plant. It also spreads by dropping parts of the stem that can regrow into new plants2. The way the plant populates makes it very thick when

Ferns have adapted to land because they have roots and vascular tissue that allows water to move farther through the plant so that they don't depend on absorption of water held on the plant.

With the results of the Starch Hydrolysis Test I preceded to the final test which is the Citrate Test. Using aseptic technique, I streaked the organism onto the surface of the Simmons’ citrate slant and let it incubate overnight at 37°C. The Citrate Test determines if the organism is able to

3. After 56 days bag was retrieved from wetland and leaves were carefully rinsed and placed into 3 separate paper bags to be dried for one week.

The wastewater of the aquaculture unit, nutrient rich effluent, allows excellent synergy between the two systems when in balance with plant fertilization needs. On one hand the nutrient enriched water of fishponds serve as fertilizers in crop

The plants that grow in saline soils have diverse ionic compositions and a range in concentrations of dissolved salts (Volkmar et al., 1998). These concentrations fluctuate because of changes in water source, drainage, evapo-transpiration, and solute availability (Volkmar et al., 1998). Due to these varying conditions, plant growth depends on a supply of inorganic nutrients, and this level of nutrients varies in time and space (Maathius and Amtmann, 1999). Either extreme condition concerning nutrients results in deficiency or toxicity in plants, and this is demonstrated by salt tolerance (Maathius and Amtmann, 1999). These conditions vary according to the plant species and growth conditions. Little is known about the genetic basis for diversity of salt tolerance in plants, and this could be partly explained through the definitions given for salinity.
