ESRM100 Questions Autumn 2006 Chapter 2 l E V39 In 2002 a train car lled with ammonia NH3 7 common nitrogen fertilizer applied in farms 7 overturned Residents A had to be evacuated for health reasons because ammonia is a strong basic compound and caustic to living tissues had free fertilizer to use on their lawns did not need to worry about their health because ammonia is not caustic to living tissues did not need to worry about ammonia spills because it evaporates in a matter of seconds 003 U Rust forming on a car body is an example of the A oxidation of iron B reduction of iron C combustion of iron D balancing a chemical equation A value of 7 on the pH scale indicates a solution A Neutral B Acidic C Basic D Compound The basic unit of an organic compound is A a glucose molecule B hydrogen atoms C carbon atoms D nitrogen atoms Elements that have economic importance are also important elements in A living things B the atmosphere C the earth and rocks D the human body Heat is infrared radiation from the sun and is characterized by having A low energy and short wavelengths B low energy and long wavelengths C high energy and short wavelengths D high energy and long wavelengths Most energy in ecosystems originates as sunlight Photosynthesis is the conversion of energy from the sun into chemical energy by Even though nitrogen makes up 78 of the air around us An A microorganisms B predators C animals D green plants The membranous organelle where photosynthesis happens is called a A mitochondria B chloroplast C nucleus D cell wall is the byproduct of photosynthesis and becomes part of a diversity of organic molecules A Protein B Glucose C Oxygen D Water Humans do not photosynthesize so we get our chemical energy from sunlight eating plants or animals that eat plants water and mineral nutrients carbon dioxide cow CANNOT directly use this nitrogen for growth A blue green algae B plants C bacteria D legumes with nitrogen xing bacteria Organisms that are genetically similar enough to breed and to produce live fertile offspring are called A omnivores B species C biological community D producers includes the 39 39 39 39 39 quoty and its 39 J39 enVironment e g water mineral resources air sunlight A ecosystem B population C food web D closed system physical N Individual food chains interconnect to form a Plants in the Organisms that photosynthesize are referred to as A synthesizers B tertiary consumers C primary producers D secondary producers which re ects the feeding relationships in an ecosystem A biological community B population C trophic level D food web An example of carbon recycling is Coal and oil being burned Respiration and decomposition Breathing out COz All of the above UOUJCD family have nitrogenfixing bacteria in the tissues of their roots Corn Legume pea Peat Oak pow During the Phosphorus Cycle phosphorus is made available to organisms after it is released from the atmosphere rocks and minerals oceans and rivers live old growth trees cow One natural source of inorganic sulfur inputs into the air and water is A phytoplankton B plant uptake C volcanic eruptions D synthetic fertilizers The First Law of Thermodynamics states that energy A is conserved since it is not created or destroyed under normal circumstances when doing work B the total amount of energy increases with work 0 is less available and has a lower energy quality each time energy is used to do work can be recycled continuously whle doing work so there is no need for external sources of high quality energy 21 Energy captured by green plants during photosynthesis supports nearly all life on earth Photosynthesis converts energy into energy that holds organic molecules together com 22 Liquid water covers nearly cow oxygen gamma rays X rays chemical radio wavelengths chemical radiant chemical ofthe earth s surface onefourth onehalf threefourths seveneights 23 Primary production photosynthesis is a process by which plants take carbon dioxide from the atmosphere and produce complex carbohydrates Knowing this process does NOT help us to understand A global carbon cycles COP why animals eat plants global nitrogen cycles how carbon is stored by plants in the tropics
