Evaluate the relative roles of natural succession and human activities in the creation of ecosystems within the British isles. (40 marks) An ecosystem is a biological community of interacting organisms and their physical environment. Ecosystems can be changed by both human activity and natural succession. Ecological succession is the observed process of change in the species structure of an ecological community over time. The time scale can be decades (for example‚ after a wildfire)‚ or even millions

string attached to it. It is non-biodegradable; which means‚ it cannot be broken down further or changed in anyway by any organism acting on it. If you bury a leaf and a plastic article under the earth for hundred years; the leaf would have turned to humus and would have fertilized the earth whereas‚ plastic on the other hand would remain in the same state however long you wait for it. To put it in simple words‚ plastic once manufactured cannot be destroyed in any

Leaf mulch is like fertilizer. They are decayed leaves that are one of the best soil conditioners that can be added to garden or crops. Unlike fresh fallen leaves‚ which are quite acidic and use the nitrogen in the soil when decaying‚ leaf mulch adds humus to the soil and amends it. While compost is excellent for improving soil texture and adding nutrients to the soil‚ the broken down mulch (often referred to as leaf mold) is the best soil amendment that can be used. Leaf mulch helps maintain soil

The parallels between The Epic of Gilgamesh‚ translated by Benjamin R. Foster‚ and the Genesis stories‚ from The Hebrew Bible‚ are uncanny. The overall theme of these stories talks about divine intervention and questions the human condition of mortality. Both of these infamous literary works address the fact that humans are the only known species capable of abstract thinking‚ moral judgment‚ and meta-cognition. While continuous belief compares this ability with the divine‚ the human life is limited

Individual Work Week 5 Suzanne Kamm EVS-1001 Everest University Online Individual Work Week 5 Soil erosion has become a serious problem for many ecosystems. Erosion occurs when the soil and hummus particles are removed from their location by wind and water (Wright & Boorse‚ 2014). This process causes the soil to erode and become ‘barren” and exposed to the elements (Wright & Boorse‚ 2014‚ p. 276). There are three major contributing factors to soil erosion: overgrazing‚ over cultivation

Phosphorus is an essential macro-nutrient for plant growth and sustainable soil management. Phosphorus nutrition can be challenging in acidic soils (e.g. Queensland) and alkaline soils (e.g. South Australia). To achieve sufficient nutrition‚ the soil needs to have a relatively high pH‚ high organic matter content‚ and moist conditions. Specific soil orders such as Vertosols‚ Kandosols‚ Sodosols‚ Rudosols‚ and Calcarosols‚ lack the requirements for phosphorus nutrition. The availability of phosphorus
