Symbiosis is the relationship between organisms and how they act. Symbiosis also means living together and they do this to avoid the competition for food. There are three types of symbiotic relationships that include; commensalism‚ parasitism‚ and mutualism. Along with the symbiotic relationships there are also two types of competitions; interspecific and intraspecific competition. Competition is when two organisms fight for the same limited resources. Commensalism is when there are two different

materials are water and carbon dioxide. Energy is taken from sunlight and the end products give out glucose and oxygen. It is the most important‚ naturally occurring process of life because all living organisms depend on it. In this process‚ plants use solar energy to produce sugar. then during cellular respiration‚ these sugars are converted into ATP. ATP is the fuel that is used by all living organisms. The conversion of the unused sunlight energy into usable chemical energy is associated with the

Overview: Discovering Ecology Ecology is the scientific study of the interactions between organisms and the environment These interactions determine the distribution of organisms and their abundance Modern ecology includes observation and experimentation The Scope of Ecological Research Ecologists work at levels ranging from individual organisms to the planet Global Ecology The biosphere is the global ecosystem‚ the sum of all the planet’s ecosystems Global ecology examines the influence

wallum is a harsh environment that is battered by the sun and wind every day and with a base of porous sand; water availability is very scarce and must be conserved. The abiotic factors in the dry wallum are that the area is exposed to high amounts of sunlight which causes a loss of water in the leaves through transpiration. Since the wallum is so dry and hot; bush fires play a major cycle in the dry wallum which the trees have adapted to cope with. The roots of the plant and tree species have to cope

How weather effect your mood? Weather can have more than a little impact on your mood. Researchers in Germany branched out beyond just sunny and cloudy and looked at temperature‚ wind‚ sunlight‚ rain and snow‚ air pressure‚ and how long the days were. The study was led by Jaap Denissen of Humboldt University in Berlin. The study had 1‚233 participants‚ all living in Germany at the time. Most of the participants were women‚ the average age was 28‚ with ages spanning from 13 to 68 years old. Study

is that as they slather on sun lotion for protection‚ they could actually be harming their skin. Overuse of sunscreen and sun block‚ which contain many potentially dangerous chemicals‚ could be even more harmful than exposure to the sun’s rays. Sunlight is produced through nuclear reactions in the sun’s core. Originally born as energetic gamma rays‚ after billions of collisions with matter‚ this radiation reaches the surface and escapes into space (Mitalas). The sun radiates light to the earth‚

EXPERIMENT PLEASE VIEW THE ANIMATION FILE FOR THE PROCEDURE Observation : 1) The region of the leaf which was exposed to sunlight turns blue in colour. 2) The region of the leaf covered with black strip turns brownish in colour. Inference : This experiment shows that sunlight is necessary for photosynthesis. Multiple Choice Questions 1) In the experiment on photosynthesis‚ the leaf is boiled in alcohol kept in a water bath because

explain how your life might be different if you could make your own food through photosynthesis. First of all if we were to be able to make our own food trough photosynthesis‚ we should have chlorophyll‚ which is the important pigment in absorbing sunlight. As an effect we will all be green in color. This may be good as there will be only one race but then again our cell must be modified in order for that to happen. Most important our cells must contain chloroplast where photosynthesis occurs. It would

photic zone is the area of an ocean that is shallow enough for sunlight to penetrate through the water. The aphotic zone is the darkest‚ deepest area of the ocean. This is how marine biologists separate this marine biome. Normally‚ the photic zone water is warmer and the aphotic zone is colder. There are two reasons for this. One is because the sunlight is able to go through the water in the photic zone‚ heating the water. The sunlight can’t reach the water in the aphotic zone so it says cold. The
