Abiotic component

Implications and Problems it Presents Brandon Gutierrez Abstract The origin of life on Earth is a difficult topic to analyze with the limited data available in modern science. Many hypothesis have been suggested to explain how life may have arisen from an abiotic environment, but the topic is still far from fully understood. One generally accepted hypothesis to explain the origin of life involves an RNA world in which RNA was synthesized abiotically and carried out both the catalytic function…

Delzon, & De Schrijver, 2014). Consequently, the advent of dry niches may explain the initial rise of the angiosperms, but cannot describe a competitive edge throughout all time periods. Hypothesis 3: Ecological Innovation of the Angiosperm Because abiotic factors often limit angiosperm dominance (Bond, 1989), an intuitive idea is that acquisition of ecological innovations (in terms of biotic interactions) have allowed for supreme angiosperm competition. Three further hypotheses are often…

nitrogen and hydrological cycles. These cycles among others, bring with them various geological, chemical, physical and biological processes (name, date). All these cycles are interconnected; matter within them is continually cycled between biotic and abiotic parts of the environment (name, date). Without appropriate nutrient and element cycling on earth, ecosystems would become unsustainable as these cycles firstly ensure that there is no waste, whilst also ensuring essential elements do not…

foundation with few erosion issues, decreasing the chances of shifting in the future. The shallow-sloping limestone makes building easier as steep inclines are not apparent. Further development and access in this area affects both biotic and abiotic components of the wetland. The area provides habitat for endangered species that would be greatly impacted through increased noise from pedestrian and vehicle traffic, along with the decrease and fragmentation of their natural habitat. There is also…

annual survival was observed for 12-20 years. Scientists have used Cormack-Jolly-Seber-Open- population models in the program MARK to estimate apparent survival. Variance-component module program MARK to estimate variation in survival. Climate data was collected by using PRISM maps for monthly minimum and maximum temperatures and also seasonal data was collected from GIS, NCDC. Scientists have applied Palmer drought severity index to assess moisture levels during the season. To assess region…

Abstract The investigation was conducted see the effects of salinity on pant life more closely, with series of plants watered with different percentages of salt water. To determine how different salinity levels effect the plants growth, and also observe the other effects, if any, that may occur to the plant. The experiment was set up and each plant was watered with different levels of salinity, and measurements of the height and number of leaves was taken twice a week. The results concluded that…

1.0. INTRODUCTION Mangroves ecosystem provide an important sources such as food, medicines, material for building and filtering pollution. Mangrove forests are among the economically highest valued ecosystems. However, increase of urbanization and climate change affected the ecological functioning and the goods and services that are provided by mangrove system. Such that, the mangrove large areas are rapidly disappearing. In addition, it is degrade the condition of remaining areas. Additionally…

What is biodiversity? Introduction Biodiversity is defined as the variety of life on Earth at all its levels and includes genes to ecosystems, as well as the ecological and evolutionary processes that sustain it (Cardinale, 2012). The Earth’s biodiversity has long been a source of wonderment and scientific curiosity, but is increasingly becoming a source of concern. The sheer diversity of life is of inestimable value. Biodiversity has a number of functions on Earth, from providing a foundation…

CHAPTER 1 INTRODUCTION Since time immemorial microorganisms have played a significant role in the life of mankind owing to the production of the myriad enzymes and secondary compounds that they synthesize (Demain 1981). These micro organism live in a highly diverse environment ranging from hot springs to deep ocean sediments. In the hyper diverse environment where one can find a specialized and unique biological niche is the intracellular space between cells of higher plants acts as suite and…

EXECUTIVE SUMMARY The ROYAL SHELL DUTCH usually called as SHELL by people all over the world. And, is known as SPDC in Nigeria (Shell Petroleum Development Company of Nigeria Limited). SPDC along with JV with NNPC, NAOC and TOTAL had planned to develop the Dodo - NAG Wells Project to meet the objectives of the company. Along with business objectives the idea of SPDC was to help locals by supplying domestic gas and bring the gas flares down (Flaring into atmosphere also known as emission of…
