A forest fire lightly burned part of the park. The fire added nutrients to the soil. The fire also helped pine cones open and dr
op their seeds on the ground. These seeds sprouted and grew into strong, healthy seedlings. What effect did the change in the environment MOST LIKELY have on the pine trees growing in the park? A) All of the pine trees died. B) The fire helped release the seeds that grew in the improved soil. C) New plants moved in to replace the pine trees that were there before. D) The seeds that dropped to the ground grew, but there were much fewer trees than before.
The forest fire increased the temperature of the environment which helped pine cones to release seeds. Low intensity of fire increases the soil fertility. The fire decomposes the humus of the soil into the black carbon. The black carbon when added to the soil enhances plant nitrogen uptake which helped the seed to grow into healthy strong seedlings.
