Ecological Resilience After Volcanic Eruption

The video describes a helicopter journey over a volcanic eruption site, highlighting the stark contrast between the lush forest and the barren landscape. Despite the destruction, signs of life and ecological recovery are observed, leading to the realization of the concept of biological legacies. This concept emphasizes that some species survive intense events, forming a foundation for ecological recovery.

What was the initial landscape the narrator saw before witnessing the volcanic destruction?

• A dry savannah

• A lush, green forest

• A snowy mountain

• A barren desert

What was the narrator's reaction to the extent of the volcanic destruction?

• It was not destructive at all

• Flowing rivers

• Tall trees

• Signs of new vegetative growth

• Complete absence of life

What evidence of insect activity did the narrator observe?

What was the big realization about life after the volcanic eruption?

• All life was destroyed

• Only plants survived
