1 Activated sludge formation by microbes treats sewage and recycles water.
Activated sludge formation in sewage treatment only serves to purify water and has no
2
impact on microbial processes.
Activated sludge formation treats sewage and recycles water, all without microbial
3
involvement.
Anaerobic digestion is a process that requires the presence of oxygen for microbial
4
activity.
Anaerobic digestion is solely responsible for treating sewage, while activated sludge
5
formation is unrelated to water recycling.
6 Anaerobic sludge digestion produces methane-rich biogas for energy.
7 Antibiotics derived from useful microbes combat harmful disease-causing microbes.
Bacillus thuringiensis (Bt) bacteria and Trichoderma fungus have no significance as
8
biocontrol agents and don't impact pest populations.
Bacillus thuringiensis (Bt) bacteria are commonly used as a food source for caterpillars in
9
agriculture.
Bacillus thuringiensis (Bt) bacteria are ineffective as biocontrol agents and have no impact
10
on insect pests.
Bacillus thuringiensis (Bt) bacteria only target non-harmful insects and do not contribute to
11
biocontrol efforts.
Bacteria and fungi in cheese production are irrelevant to texture, flavor, and taste, and
12
they have no influence on the final product.
Bacteria and fungi in cheese production negatively impact the quality of the cheese,
13
making it less appealing to consumers.
Bacteria and fungi play no role in contributing to the texture, taste, and flavor of cheese.
14
15 Baculoviruses and Trichoderma are used for species-specific insect control.
16 Beneficial insects contribute to biocontrol in organic farming.
Biocontrol agents like Ladybirds and Dragonflies actually contribute to the proliferation of
17
pests rather than managing them.
Biocontrol agents like ladybirds and dragonflies are dangerous pests that destroy crops
18
instead of helping control pests.
Biocontrol methods involve using beneficial microbes to manage harmful pests and reduce
19
the need for toxic pesticides.
Biodiversity in organic farming disrupts the balance of ecosystems, leading to increased
20
pest infestations.
Biodiversity in organic farming promotes balanced ecosystems, managing pests through
21
natural checks and balances.
22 Biofertilizers are chemical compounds that harm soil health and hinder plant growth.
23 Biofertilizers are eco-friendly alternatives to chemical fertilizers.
Biofertilizers containing microbes degrade soil quality and accelerate soil degradation,
24
leading to reduced agricultural productivity.
Biofertilizers containing microbes harm soil health and contribute to nutrient depletion,
25
reducing agricultural sustainability.
Biofertilizers made of bacteria, fungi, and cyanobacteria have no impact on soil fertility
26
and crop yield.
27 Biogas is a greenhouse gas that contributes to global warming and climate change.
Biogas production is entirely unrelated to microbial activity, instead relying on chemical
28
reactions.
Biogas production using microbial activity is an eco-friendly way to generate energy from
29
organic waste.
