stunted trees are capable of a sudden growth surge when a gap in the canopy opens above them. The air beneath the lower canopy is almost always humid. The trees themselves give off water through the pores of their leaves. This process‚ called transpiration‚ can account for as much as half of the precipitations in the rainforest plants have made adaptations that help them shed water off their leaves quickly so the branches don’t get weighed down and break. Many plants have drip tips and grooved leaves

The First World War was a time when all types of military technology underwent significant advancements and these had a major influence on the outcomes of battles‚ numbers of casualties and ultimately on the victory of the Triple Entente. Though both sides waged war on air‚ land and sea‚ some of these facets of military effort held more importance in the war and its outcomes‚ than others. Though aerial warfare caused more civilian casualties and destruction‚ it was naval warfare had the most significant

Introduction Water is known as a vital component to sustain life. When one is confronted with the fact that water is considered a renewable resource in the short term but only 3% is usable (N.Gray)‚ precautions must be taken to ensure the conservation of water. The agriculture industry consumes approximately 70% of the planet’s usable water globally. At large scale the water footprint arguably cannot be reduced‚ raising the question on whether our water is being used to its full potential. Water
