  •  Protista
  •   Cyanobacteria
  •  Fungi
  •  All of these
b) Cyanobacteria.

Q2. Methanogens, growing anaerobically on cellulosic material, produce
  •  Methane
  •  Methane and carbon dioxide
  •  Methane and hydrogen
  •  Methane, carbon dioxide and hydrogen
d) Methane, CO2 Hydrogen. Biogas is a methane rich fuel gas produced by anaerobic breakdown or digestion of biomass with the help of methanogenic bacteria. Biogas is made up of methane, carbon dioxide with traces of hydrogen

Q5. Which of the following statements regarding baculoviruses as bio-control agents is/are correct?
I. Baculoviruses are pathogens that attack insects and other arthropods
II. Most of these biocontrol agents belong to the genus Nucleopolyhedro virus
III. They do not harm plants mammals, birds, fish and other non-target insects
IV. Baculoviruses are helpful in Integrated Pest Management (IPM) programme, in which beneficial insects are conserved
Choose the correct option
  •  I, II and III
  •   I, II and IV
  •  II, III and IV
  •  All of these
d) Baculovirus heliothis (a group of virus) are known to infect the larval stages of many harmful insects beetles, wasps and ants. A number of baculovirus, which are used as biopesticides belongs to the genus Nucleopohyledro virus These biological weapons are not only effective as potential biological control of harmful insects, but are also harmless to non-target organisms insects (plants, birds, mammals, non-targets insects etc). They are important in organic farming because of their specific action on harmful insects without causing any damage to beneficial insects as well as to the environment. Baculoviruses are helpful in Integrated Pest Management (IPM)Programme, in which beneficial insects are conserved

Q6.  Morphine, which is used as an analgesic is obtained from
  •   Cinchona officinalis
  •  Papaver somniferum
  •   Taxus brevifolia
  •  Berberis nilghiriensis

  • Energetic nutrients
  •  Constructive nutrients
  •  Energetic and constructive nutrients
  •  Protective nutrients
Q8. The free-living fungus Trichoderma can be used for
  • Killing insects
  •   Biological control of plant diseases
  •  Controlling butterfly caterpillars
  •  Producing antibiotics
b) Trichoderma is a free living saprophytic fungi that most commonly lives on dead organic matter in the soil and rhizosphere. It acts as a biopesticides for control of many soil borne disease

Q9.Secondary sewage treatment is mainly a
  •  Chemical process
  •  Physical process
  •  Mechanical process
  •  Biological process
(d) Secondary treatment of the liquid effluent from the primary settling tank is purely a biological treatment involving microbial activity .

Q10.  Which of the following microbe convert milk into curd?
  •  Bacteria
  •  Virus
  •  Fungi
  •  Protozoa
(a) In the process of making curd, bacteria convert milk into curd and milk protein into predigest milk protein. These bacteria then inside the growth of hostile (illness causing) bacteria inside the intestinal tract and promote beneficial bacteria needed for digestion .
