Birds swallow some seeds which come out with
their droppings. Squirrels collect nuts and bury

them to be used in winter. They often forget
where they had buried the seeds. So when the

conditions become favourable, these seeds
grow into new plants. While eating fruits, some
seeds get stuck on the beaks of birds. When they

rub their beaks on the bark of trees, the seeds

Coconut can be dispersed by water fall down and later on they grow into new plants.
CROPS

Healthy crops are important because they help in feeding the people of a
country. A good crop adds to the wealth of the nation. There are several things

that farmers keep in mind while growing crops. The following are the various
stages for growing a healthy crop.
a. Ploughing the field b. Sowing the seeds

c. Addition of fertilizers and manure d. Irrigation

e. Crop protection f. Harvesting g. Storage
Ploughing the Field

Ploughing is the first preparation for growing crops. The purpose of ploughing
is to turn over the upper layer of the soil and bring the fresh nutrients to the

surface. It also helps in burying the weeds and the remains of previous crops,
allowing them to break down. Ploughing aerates the soil and allows it to hold
moisture.

Sowing the Seeds
Sowing is the first stage process of planting.
