Which factors (limited space or overcrowding; limited food; Predators; parasite and diseased) tend to act in a density-dependent manner; Tony Sinclair (1989) many studies of density dependence in 51 populations of insects, 82 populations of large mammals, and 36 populations of small mammals and birds. Which of the following observation is most likely true?

a) Insects showed a wide variety of causes of density dependence and no one density-dependent factor was of overriding importance

b) The lesser the amount of available food, the greater the mortality of large mammals

c) Space and social interactions were more important for smaller mammals and birds, because they are more territorial

During  a  field  trip,  an  instructor  touched  a  moth  resting  on  a  tree  trunk.  The  moth  raised  its  forewings  to  reveal large eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answered that sensory  receptors  had  fired  and  triggered  a  neuronal  reflex  culminating  in  the  contraction  of  certain  muscles.  A second student responded that the behaviour might frighten predators. Which statement best describes these explanations?
