Answer 1

This is because of seed dispersal. Seeds are dispersed away at different places from the parent plant through the means of wind, water, animals etc. Seed dispersal is important because:

1. it prevents overcrowding of plants at a particular place.

2. after the seeds are dispersed they get enough space and essential nutrients

3. seed dispersal is important because it helps plant to invade new habitats for wider distribution.

Answer 2

These small plants that Paheli saw are weeds and they grow from the seeds dispersed by birds when they come and sit in the garden.  

Explanation:  

• Weeds are considered to be a bane for gardeners as these rampantly grow in gardens and hijack the nutrition provided to plants and hinder the latter’s growth.
• It is during monsoons that weeds grow a lot and it is required by the gardeners to identify and pick the weeds. These weeds generally grow from the seeds dispersed by the birds when they come and visit the gardens.
• As birds fly everywhere often the seeds get stuck in their beaks and they fall in different spaces.
