Answer:

Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

Answer:

The basic difference between primary and secondary succession is the presence of soil. When primary succession begins, soil is not present; in the case of secondary succession, soil is already in place.

D) Psychrotrophs.

Explanation:

  • Psychrotrophs are those bacteria which can tolerate cold temperature and have optimum growth above 15 degree Celsius.
  • Halophiles prefer high salt concentration.
  • Mesophiles prefer temperatures with a average of 37 degree Celsius.
  • Anaerobes grow in absence of oxygen.
  • In the given experiment, none of the bacterial cultures were placed in saline or anaerobic conditions. So, the bacterial species is not an anaerobe or halophile.
  • Again the cultures did not show growth at 37 degree celsius so they are not mesophiles.
  • Maximum growth at 22 degree celsius and a little growth in refrigerator make it obvious that the species is a Psychrotroph.
