environment. As the seasons change‚ the temperature and climate affect the biotic and abiotic factors. Biotic factors are the living organisms that are affected by abiotic factors. Abiotic factors are the non-living or physical factor that directly affects the living organisms. Etosha displays all type of biotic and abiotic factors as the seasons change and the rainy seasons come again to start the cycle again. A biotic factor is the predator and prey relationship. Etosha displays this through many

Ever since the 1960’s‚ The Crown of Thorns Starfish have been destroying our magnificent Great Barrier Reef. Biotic factors are a major consideration of the outbreak of the Crown of Thorns‚ lack of predators and their high fertilization rate plays a massive role in this overwhelming amount of starfish. The main predator the COT meets is the giant triton snail1. But because of recent population problems making the predators lacking in numbers they have no way of reducing the crown of thorns population

Introduction: The focus of this investigation is to compare the distribution of Mayfly nymphs (Ephemeroptera) and Stonefly nymphs (Plecoptera) in both the Tiritea stream and the Mangaone Stream and also to analyse the distribution of the Mayfly and Stonefly nymphs in relation to biotic and abiotic factors. Also‚ habitat patterns (or absent) are identified that the organisms follow

determining the amount of light needed for optimal growth. Introduction Plants are able to convert light energy into chemical energy through the process of photosynthesis (Campbell & Reese‚ 2005). This process is dependent on both abiotic and biotic factors. Since plants are autotrophs‚ the most vital are abiotic factors such as light‚ temperature‚ wind‚ water‚ and atmospheric gases (Campbell & Reese‚ 2005). The plant of interest in this study is Lemna minor. Duckweed is a small aquatic watering

Every single say we affect the lithosphere‚ whether we know it or not. Simple things just like a little rain effects it. Ways that processes and forces affect the lithosphere is water. When it runs off it causes chemical reactions that break down rocks. The rainwater dissolves the rocks to form caves and to move rock and soil to other places. By doing this is causes major erosion. Erosion is very bad because it slowly breaks away soil‚ and takes out all the nutrients that plants need to survive.

Ecosystems – “An assemblage of parts working together forming a functioning whole.” “A community of independent organisms and the physical environment they inhabit.” All systems have many small parts working together. A system can be living (BIOTIC FACTORS) or non-living (ABIOTIC FACTORS) and has inputs as well as outputs. A system can be an abstract concept as well as something tangible. All systems have: * STORAGES * FLOWS * INPUTS + OUTPUTS * BOUNDARIES * PROCESSES There
