Answers:they have mechanisms to control their temperature so they can regulate enzymatic reactions shivering thermogenesis non-shivering thermogenesis muscular contractions/relaxation increasing/decreasing metabolic rate movement to different areas for shade/sun
Answers:ectothermic organisms don't produce heat via metabolism like endothermic do so they have to get heat from the enviro like by laying in the sun. therefore they can not produce energy unless they are warm as cells work best at optimum temperature. therefore the higher the temperature the more energy they will have to go get food and create more energy.
Answers:there is a very approximate rule for the rate of organic chemical reactions the reaction speed doubles for every 10C (22F) rise in temperature and therefore because the ectotherm assumes the temperature of its surroundings, the graph would be exponential (assuming that the ectotherm was attempting maximum metabolism) however because the solubility of oxygen (in water decreases with temperature) this would limit maximum metabolism unless the water was flowing adequately (perhaps with gill action, for instance)
Answers:unfortunately the answer has nothing to do with the experiment. photosynthetic organisms serve as the primary producers in the food chain and then the primary consumer feeds on them which will be preyed upon by the secondary consumer etc. as the primary producer they don't have to depend on other organisms to make food for them because they make their own. they capture the energy from the sun and pass on this energy to the consumers that depend on them for food. as one goes higher up the food chain, there's less energy. moral of the story: eat more fruits and vegetables if you want maximum energy
