With reference to one plagioclimax that you have studied, assess the impact of human activity on plant succession. (10 marks) Plant succession is the process by which one plant community replaces another over time. Human activity can have an impact on the succession of plants in a number of ways these are known as arresting factors. A plagioclimax community is a habitat in which the impact of humans has subsequently meant that the ecosystem has been prevented from developing further. The plagioclimax

and water enter the spaces between the particles and chemical changes take pace which resut in the production of chemical substances. Bacteria and plant life soon appear. When plant and animal organisms die, they decay and produce a substance called humus. This is very important to so fertility. Bacteria play a vital role into the decomposition of plants and animals remains. The end product of these mechanical, chemical, and biological processes is called soil which is one of the world’s most important

rainforest, specifically a coastal hill dipterocarp forest. (H.T.W. Tan et al.). Such forests were the most common in areas with year-long moisture and well-drained soils, as found in Singapore. (R.J Morley). Such forests are dense, and lack ground plant growth. They also have a higher diversity of flora and fauna as compared to other forest types. Due to clearance of the forest by man for the cultivation of rubber, pepper and pineapple crops in the past, the forest had lost its original vegetation

BIO 1020 – Fall 2012 Laboratory 1: Bacteria and Protists pp. 1-29 You will be required to identify all of these organisms by kingdom and phylum/division (phylum = animal, division = plant). If a genus name (italics) is given on this handout, you will be responsible for that as well. You must know all of the structures and terminology listed below. Due to the ever-changing nature of biology, the nomenclature used in lab may differ from that used in lecture. A labeled drawing and short written

have been cut under which coffee was grown. The shaded coffee plants were resting places for migrating songbirds like warblers, orioles, wood thrushes and fly catchers. Thhese coffee plants were their food. Now there are fewer species of birds in the sun shaded coffee plants as compared to shade grown coffee plants. Many insects like orchids, amphibians and reptiles lived on shaded coffee plants but they cannot live on sun grown coffee plants. Stats show that sun coffee varieties has three times more

Energy flow through an Ecosytem The ecosystem uses energy from the sun when the plants use a process called photosynthesis. This process is when the plant uses the sunlight to make sugar molecules. Also during this process the plants gain solar energy. The

Water makes up the biggest part of the biosphere, marine biomes are larger than the other water and land biomes put together, it mostly covers nearly 75% of the surface. regions house a lot of species, plants and animals, both large and small. This is where life began billions and millions of years ago when amino acids first started to come together. Without water, most life forms wouldn’t be able to sustain themselves and the Earth would be bad like, desert-like place. Although water temperatures
