that enabled me to understand deeply the role of human kind in the protection and conservation of our natural resources. Our group research entitled “Phytoextraction Potential of Rose Moss Plant (Portulacagrandiflora) on Lead-Contaminated Soil in Different Soil Treatments” particularly studied the plants capability in extracting the heavy metal Lead (Pb) from contaminated soils collected by the river banks of the Marilao River in Bulacan. Prior to experimentation‚ we tested for the initial Pb

Basic Ecological Concept Levels of Organization Cells- are composed of Cell Membrane‚ Nucleus and Protoplasm. Tissue-is an aggregation of cells performing a common function or functions. Organs- is the aggregation of tissues usually forming a definite shapes‚ and performing a definite function within an organ system. Organ System-is a group of organs that perform coordinated functions together to keep the organism alive and functioning well. The scope of the biology includes the study of all

and ensure the survival of lichens‚ trees‚ flowers‚ and bees. Action 1 = Reduce pollution as said many times by experts but nothing is really being done. Action 2 = Put a plan to use in reducing pollution. There are fossil fuels and we can still plant trees and flowers. Action 3 = Spread this plan and put it to use. People are doing small things like recycling but not enough are doing this. I hardly see proper recycling and there is nothing to

The increasing demand for forest wealth love threaded the diversity forest resources and thus there is need for conservation of the different plant species in their natural habitual. Tinsukia district is very rich for its rich biodiversity. And on such important species is the Orchids. Orchids belong to the most diverse family of plants known to man. There are over 880 genera‚ 28‚000 species and well over 300‚000 registered cultivars currently documented

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

quality can be defined as the overall activity of a soil within an ecosystem that preserves biological activity and environmental quality‚ thus promoting plant and animal health (Doran et al. 1994). Alterations in soil properties and processes can affect functions that soils perform in the environment‚ which in turn influence patterns of plant growth (Ahuja 2003). Changes in land use influence several soil processes‚ such as oxidation‚ mineralization‚ leaching‚ and erosion‚ thus modifying soil function
