Detailed explanation-2: -Positive effects of fire heats the soil, cracking seed coats and triggering germination. triggers woody seed pods held in the canopy to open, releasing seed onto a fresh and fertile ash bed. clears thick understorey reducing competition for seedlings. encourages new growth that provides food for many animals.

Detailed explanation-3: -Wildfire, also called forest, bush or vegetation fire, can be described as any uncontrolled and non-prescribed combustion or burning of plants in a natural setting such as a forest, grassland, brush land or tundra, which consumes the natural fuels and spreads based on environmental conditions (e.g., wind, topography).
