World Biomes Task 2: Main characteristics of grasslands. Grassland biomes are ecosystems predominantly consisting of a diverse range of grasses. Grasslands are generally flat terrains of rolling grass which are vast and continuous. The widespread of grasslands occurred during the Miocene and Pliocene Epochs in Western North America‚ where continental climates became favourable to grasslands as a result of the rise

in warm or dry areas‚ own or have access to a swimming pool. While this attraction can be relaxing and fun on a hot summer day‚ it has tremendous consequences on the environment. The use of chlorine greatly affects the plants and wildlife surrounding the area. It can cause plants to wither away‚ turn yellow‚ and even die. The chlorine can cause the tissue of leaves to brown or rot. The toxicity can even cause microorganisms in the surrounding soil to die. Chlorine is also used in many household items

However‚ with modern genetics and the theory of evolution‚ we know that it is unlikely that members of the Orchidaceae family are the restoration of a satyr. However‚ this does not dampen the mystical fascination of humans with this family of flowering plants. Undeniably‚ the beauty of many members of Orchidaceae has mesmerized many and led to a huge floricultural industry in the trade of orchids and its hybrids. Vanilla‚ one of the most used flavourings‚ is derived from the seed capsules of orchids. Orchidaceae

in the planet with human beings. Organisms like plants‚ animals‚ mammals‚ bacteria and many more. These organisms are divided into groups:- Animalia‚ Plantae‚ Protista‚ Archaea‚ Bacteria and Fungi. Respiration is the process of releasing energy from glucose or any other organic material. The chemical energy in glucose is used for growth and movement. But the process of respiration in plants is different to those in animals. In respiration plants use carbon dioxide and burn the sugars they produced

Feeding Relationships Found in Nature. Plants make their own food. Therefore‚ plants are called producers. You know that animals depend on plants or on other animals for their Food. Therefore‚ animals are called consumers. A study of feeding relationships‚ or food chains‚ helps us to better understand our environment. And if we study the feeding relationships in an environment‚ we are better able to predict what will happen if the plants and animals are threatened in any way. For example

Buttresses are often found in locations with poor soil quality. In biomes like the temperate deciduous forest biomes the trees have no need for buttresses because the soil is rich with nutrients. Rich soils allows for trees and plants to grow deep roots that anchor and provide them with stability. In addition deep root systems take up nutrients that are found throughout soil. Buttresses do not penetrate into the deep layers of the soil this could affect stability in places like

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

Carnivores can affect the size of prey populations in a community and determine the places prey can live. Herbivores can affect both the size and distribution of plant populations in a community and determine the places that certain plants can survive and grow. For example: let A represent a carnivore‚ B represent a herbivore‚ and C represent plants. If A is abundant in a given area‚ there will be less B because A hunt B. Since B hunts C‚ there will be more C where there are more A‚ because of the lack

transfer factors (TF) of 40K‚ 238U and 232Th are presented from table 4.1 – 4.33. The geometric mean and the geometric standard deviation for each table were calculated using equations 2.47 and 2.49. Since the TFs are the ratios of the concentrations in plant and soil respectively‚ the geometric mean is used because it is the most appropriate when calculating the mean of ratios. All the values of the TFs stated below are respectively for 40K‚ 238U and 232Th with the geometric mean and the corresponding
