- Read this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.Organisms have developed defense mechanisms to protect themselves from predation. These defense mechanisms include protective colouration Mullerian mimicry Batesian mimicry cryptic colouration chemical defense Match the following examples to the type of protective mechanism listed above.Stripes of a skunk AnswerA fawn with fur colouring that camouflages it in the forest AnswerTwo species of poisonous butterfly with the same colour pattern AnswerA hawkmoth with the same black and yellow body markings as a wasp Answerforest sites than in forest fragments, whereas there were no significant differences between fragments of different sizes. These results provide further evidence for the effects of habitat size on the phorid-Acromyrmex system in a tropical rain forest, based on the abundance of parasitoids both as adults in the field and as reared immature phorids in the laboratory. Phorid parasitized leafcutter ants were most abundant in areas of continuous forest, and less abundant in the forest fragments. O Phorid flies are important parasitoids of leafcutter ants nd leafcutter ants can be found in Brazil's Southeastern Both phorid flies Atlantic Forest. The study provides evidence that this parasitoid-host interaction between phorid flies and leafcutter ant differs between continuous forest and forest fragments. Phorid flies were just as abundant in forest fragments as they were in continuous forest, but were less successful in parasitizing leafcutter ants.
- Poison or toxic compounds can be an adaptation for survival in both predators and prey. True False Parasitism is an example of a symbiotic relationship. True False Predation and herbivory are similar interactions (-/+) in that one organism in the interaction benefits and the other is harmed. True False 4.)Competition is an interaction (-/+) that is negative for one organism and positive for the other organism. True False 5.)Plants are defenseless against herbivory by animals. True FalseOf these choices, which best describes an organism's niche? Question 10 options: The set of conditions under which Libeg's law no longer applies The area/conditions where all of its physiological tolerance ranges overlap None of these are even close. The places it could live after a few generations of adaptation All of the locations where actual and potential evapotranspiration are equal.Question 73 Match the description to the specific type of symbiosis. "win-win" symbiosis, both partners benefit [Choose] [Choose ] "win-lose" symbiosis, one partner benefits, the other is harmed utopianism mutualism "win-neutral" symbiosis, one partner commercialism benefits, other neither benefits nor is harmed commensalism parasitism
- Moths resting on the trunks of trees often resemble the tree bark such that potential predators do not perceive them as prey. This is an example of: an induced defense. aposematic coloration. crypsis. silencing.Choose the type of symbiotic relationships with their correct definitions. The 4 options are: mutualism, commensalism, parasitism or none of the above. Please explain in details why each option was selected.Definitions: One species kept alive to benefit the other species Both species benefit from forming a symbiotic relationship Neither of the species benefit from forming a symbiotic relationship While one species increases its survivability, the other species neither benefits nor suffers from the symbiotic relationship One species benefits greatly while the other species diesWhich of the following is an associative behavior in which two organisms have no effect on one another? Question 3 options: Amensalism Neutralism Commensalism Parasitism The breeding of an organism for a specific trait is called: Question 10 options: Artificial Selection Behavioral Adaptation Structural Adaptation Evolution
- Population structure and genetic associations describe the case where symbiont partner genotypes are not distributed randomly across a host or the landscape in which a host resides. Describe how population structure and genetic associations could resolve the problem of cheating in mutualism.The figures below show a tobacco hornworm that can only eat well chemically defended tobacco plants (specialist) and the a gypsy moth larvae that can eat leaves of many plants that are not well chemically defended, but often can't eat leaves of plants with specialized chemical defenses (generalist). Assume you have observe a patch of land that was planted with tobacco and some tree species that don't have specialized chemical defenses. How might the abundance of the tobacco plant most likely be affected differently by the generalist herbivore and by the specialist herbivore? Tobacco Hornworm Gypsy Moth The gypsy moth may increase the abundance of tobacco by choosing to eat the tree saplings The gypsy moth larvae may decrease the abundance of the tobacco plant by eating the leaves of the tree saplings The tobacco hornworm may increase the abundance of tobacco by chasing gypsy moth larvae away from the plants. The tobacco hornworm might decrease the abundance of tobacco by feeding on…Name each type of mimicry: Batesian Mimicry The harmless locust borer beetle looks, and even sounds like a bee. Mullerian Mimicry Apheloriine millipedes of the temperate North American forest produce enough hydrogen cyanide to kill a pigeon. The different Apheloriine species are all toxic and all have similar bright coloration.
