serotinous cones  are sealed with a resin that prevents seed dispersal & the cones of a jack pine tree are serotinous cones ->  the cones of a jack pine tree are sealed with a resin that prevents seed dispersal  the cones of a jack pine tree are sealed with a resin that prevents seed dispersal & serotinous cones  are sealed with a resin that prevents seed dispersal0 ->  the resin on the cones of a jack pine tree that prevent seed dispersal can be melted with heat  burning trees is used to produce heat & a forest contains many trees ->  burning a forest can produce great amounts of heat  burning a forest can produce great amounts of heat & wildfire is when a forest catches fire ->  a wildfire produces great amounts of heat  the resin on the cones of a jack pine tree that prevent seed dispersal can be melted with heat & a wildfire produces great amounts of heat ->  a wildfire can melt the resing that prevents seed dispersal off of the cones of a jack pine tree  a wildfire can melt the resing that prevents seed dispersal off of the cones of a jack pine tree & melting something off of something else is a lind of method for removing something from something else ->  a wildfire can remove the resin that prevents seed dispersal from the cones of a jack pine tree  a wildfire can remove the resin that prevents seed dispersal from the cones of a jack pine tree & removing something that prevents something else causes that something to be able to do that something else ->  a wildfire causes jack pine tree cones to be able to disperse seeds  dispersing seeds is a kind of action for trees & something will perform an action after something else causes that something to be able to perform that action ->  a tree will disperse seeds after something else causes that tree to be able to disperse seeds  a wildfire causes jack pine tree cones to be able to disperse seeds & a tree will disperse seeds after something else causes that tree to be able to disperse seeds -> a jack pine tree will disperse seeds after a wildfire
