The canopy is the zone of the highest foliage and branches of a forest. The layer which is the “shrub layer” and these are where the woody plant smaller than a tree, usually have several stems from the same base and where young tree, bigger than a seedling usually are. Lastly is the layer known as the ground layer which is the lowest part from the uppermost part. The rainforest traps about eighteen percent of manmade gases. Tropical rainforest are important because the plants provide chemicals used as blueprints for making most of the world's prescription drugs and they absorb excess carbon dioxide.
Environmental changes are occurring, such as deforestation. Some lemurs rely on certain diets, like the bamboo lemur which eats only bamboo. Deforestation occurs when loggers clear-cut the trees and natural habitat of the lemurs. It is a longer process to evolve to the changes than it is to clear the habitat in which the lemurs live and eat. Using the bamboo lemur as an example, if people continue to cut down the bamboo, the lemurs will not have food and they could become extinct very quickly.
e. none of these ____ 8. Hydrophobic reactions of phospholipids may produce clusters of their fatty acid tails, which form a. a lipid bilayer. b. hydrolysis of the fatty acids. c. a protein membrane. d. a cytoskeleton.
Each carrier in the chain has a slightly lower energy level than the previous, so the remaining energy is used to combine Adenosine Di-phosphate with an inorganic phosphate molecule to make ATP cellular energy. Consequently, this ATP along with reduced NAPD co-enzyme are utilised in the light-independent reaction or Calvin Cycle to reduce CO2 and other carbon containing compound such as Glycerate-3-phosphate and triose phosphate into essential organic compounds such as glucose. The overall photosynthetic equation is 6CO2 + 6H2O C6H12O6 + 6O2. For photosynthesis to occur, oak trees require a plentiful supply of water and carbon dioxide -Water Transport and Root pressure and salts -CO2 stomata Because glucose cannot always be used up as
The rate of carbon dioxide utilization 2. The rate of formation of organic compounds 3. The rate of oxygen production 4. Explain how the light and dark bottle method rate oxygen production is used to measure aquatic net productivity. The light and dark bottle method of rate oxygen is used to measure aquatic net productivity because the amount of light determines whether photosynthesis can occur.
Competition for resources is a common sight in any ecosystem. Competition is more intense for resources which are shared by more organisms. In rainforest where sunlight is being competed for by trees, strangling figs can be found competing for light. In river, caddisfly and mayfly compete for algae. Figure 1: Strangling fig in Gombak Rainforest Abiotic factors Non-living components of an ecosystem make up the abiotic factors.
BIOL 103 Final Exam Solution https://hwguiders.com/downloads/biol-103-final-exam-solution/ BIOL 103 Final Exam Solution Question 1 Which statement about evolution is FALSE? Question 1 option: According to evolutionary theory, you are related to a bacterium, to a yeast cell, to a snake, and to a whale. In fact, you are related to every species now alive on Earth, and to fossil species like dinosaurs as well. Natural selection acts on genetic differences within a population to cause evolution. Individuals do not evolve.
The process of photosynthesis is when plants use the energy in sunlight to convert water and carbon dioxide into oxygen and high-energy carbohydrates. Photosynthesis occurs inside a cell organelle called the chloroplast. The chloroplast contains green pigments called chlorophyll, which capture the energy in sunlight. The equation for photosynthesis is as follows: Light 6CO2 + 6H2O à C6H12O6 + 6O2 (Moran 2006) The raw materials needed for photosynthesis are carbon dioxide from the air (taken in through the leaves) and water, usually from the soil (taken in through the roots). The two combine initially to produce simple sugars and oxygen.
The pH test was used determine the overall acidity of the water, which is indicative of what organisms can and cannot survive in the water. Testing Secchi depth shows the depth at which visible light can no longer be seen from the surface, and the compensation depth is the depth at which only 1% of surface light penetrates the water column (McNeil, 2014). In order to gather information on what organisms are present in the lake, sediment samples were taken from different zones and analyzed under compound and dissecting microscopes. Methods During this lab our goals were to find the average acidity of the surface water, the average compensation depth, dissolved oxygen and temperature with depth, collect plankton samples, and collect sediment samples. The first test was to find the dissolved oxygen content and water temperature at various depths of the lake.
In temperate deciduous woodland there are both human and physical factors which account for the change to vegetation over time within the ecosystem. The main human factors are for timber supply and recreation. Pollarding is a method that is used to manage woodland. This involves the trees to be shoulder height above the level of browsing by animals such as deer. By pollarding trees at this height it means that the tree is able to survive and therefore can carry on to row and supply wood.
