Question 1:


Imagine a situation where a large, established forest is suddenly destroyed by a massive wildfire. The fire reduces all the plants and wildlife to ashes, effectively resetting the ecosystem. After a few years, the forest begins to regrow, and different species of plants and animals start to repopulate the area. As the ecosystem recovers, how would you predict the flow of energy and matter would progress from this event? Consider the various stages of recovery and the types of organisms that would inhabit the forest at each stage, and provide a reasoning for your answer based on your understanding of the flow of energy and matter in ecosystems.
