Question

Some species of pine are adapted to their fire-prone habitats by having tightly sealed cones that open and shed their seeds only after being exposed to high________ . This allows seedlings to take advantage of the abundant resources available after a fire.

Answer 1

Answer: temperatures

Step-by-step explanation:

The fire is an ecological factor which is responsible for opening up cones of pine trees and allow their seed dispersal. The forests fire is a naturally occurring environmental factor. The forests fire provides the high temperature which melts the waxy resin seal present inside the pine cone and hence, the hard woody cones open up to spread the seed. This is necessary for the colonization and abundance of pine trees in the forests.
