Question

1.
Differentiate between insecticides, rodenticides and fungicides. Which of these are

pesticides?

2.Discuss with an example how hybridization is used for developing new varieties of crops with

desired characteristics.

3.Differentiate between nitrification and denitrificati​

Answer 1

Answer:

Insecticides are chemicals used to kill insects like locusts. Rodenticides are chemicals used to kill rodents like rats. Fungicides are chemicals used to destroy fungi. ... So insecticides, rodenticides and fungicides are all pesticides

Answer 2

Insecticides are chemicals used to kill insects like locusts. Rodenticides are chemicals used to kill rodents like rats. Fungicides are chemicals used to destroy fungi. ... So insecticides, rodenticides and fungicides.

Hybridization involves cross-breeding two different varieties of crops to obtain a new variety with the desired traits. Example: Two varieties of crops, one with high yield and other with disease resistance, can be crossbred to obtain a variety that has both the traits, i.e., high yield and disease resistance

3.Nitrification is the second step of the nitrogen cycle. Denitrification is the last step of the nitrogen cycle. Nitrification involves the conversion of reduced nitrogen compounds into oxidized forms. Denitrification involves the conversion of oxidized nitrogen compounds into reduced forms.
