Q-10.Suppose there were a bird that always sat on a horse’s back and ate the insects that would bite the horse. What would this be an example of?










  1. a
  2. b Explanation- Abiodiversity hotspot is a biogeographic region with a significant reservoir of biodiversity that is under threat from humans.
  3. A Explanation – Inecology, commensalism is a class of relationship between two organisms where one organism benefits without affecting the other. It compares with mutualism, in which both organisms benefit, amensalism, where one is harmed while the other is unaffected, and parasitism, where one benefits while the other is harmed.
  4. B Explanation- Afood web (or food cycle) depicts feeding connections (what-eats-what) in an ecological community and hence is also referred to as aconsumer-resource system.
  5. C Explanation- Habitat fragmentationdescribes the emergence of discontinuities (fragmentation) in an organism’s preferred environment (habitat), causing population fragmentation. Habitat fragmentation can be caused by geological processes that slowly alter the layout of the physical environment  (suspected of being one of the major causes of speciation), or by human activity such as land conversion, which can alter the environment much faster and causes extinctions of many species.
  1. B Explanation- this can be understood with an example- suppose you use pesticide on an insect population. At first it seems to be working and most of the insects died. Those who survived somehow carried the gene that has pesticide resistance. These insects with pesticide resistance quickly reproduced and passed on their genes. Over time natural selection occurred and the pesticide resistance became less effective. Note that environment changes does not create new alleles that are beneficial in the environment but rather natural selection selects alleles from a populations gene pool that will be beneficial. Thus natural selection acts on population and its gene pool (not gene).
  2. D
  3. D
  4. B
  5. A Explanation- mutualism is the interaction in which both the organisms are benefitted. In this case bird is getting food by eating insect and the horse is getting rid of the insect that would bite it hence this interaction is mutualism.
