Question

How are pine seeds dispersed?

Answer 1

They can be dispersed in multiple ways.

1) Animals eat pine seeds and spread them around by defecating them and letting them grow.

2) Sometimes if the pine seeds are in a windy environment, they can be blown around and spread.

3) Some are dispersed by water. Currents can carry seeds across oceans, lakes and rivers, and they end up on shores where they can grow.

4) There is manual dispersing, where humans plant pine seeds.

Assuming all seeds end up on a habitable environment for them(basically any place on land where there's sun) to grow, they should be able to grow into pine trees.
