Question

the figure above shows the same ecosystem in texas at two different times, 1984 and 2004. which of the following most likely caused the change of species shown in the figure?
a development of a parking lot
b passing through of a glacier
c preservation of habitat
d occurrence of a forest fire

Explanation:

• Option A: A parking lot development would lead to more urban - like changes, not the shift from forest to grassland - like shown.
• Option B: Glaciers are not common in Texas, so this is unlikely.
• Option C: Habitat preservation would maintain the original forest - like ecosystem, not cause the change seen.
• Option D: A forest fire can destroy trees (the 1984 forest - like scene) and allow grass - like vegetation (2004 scene) to grow, which matches the ecosystem change.

Answer:

D. occurrence of a forest fire
