Plant growth – Clip

In dense forests, fallen seeds often fail to germinate due to insufficient light. A forest fire can provide a solution by burning the mountain ash, which releases its seeds. The fire also clears the undergrowth, allowing the seeds to receive ample light and promoting their growth.

Why do the seeds of the mountain ash struggle to germinate in the forest?

• They are eaten by animals.

• They lack sufficient light.

• They are washed away by rain.

• They are buried too deep in the soil.

What is the primary obstacle for seed germination in the thick forest undergrowth?

• Lack of water

• Lack of light

• Lack of nutrients

• Lack of space

What event causes the mountain ash to release its seeds?

• Animal activity

• A forest fire

• Strong winds

• Heavy rainfall

What role does the forest fire play in the life cycle of the mountain ash?

• It prevents seed germination.

• It helps in seed dispersal.

• It destroys the seeds.

• It provides shade for the seeds.

How does the forest fire benefit the fallen seeds?

• It provides nutrients to the soil.

• It clears the undergrowth, providing light.

• It scares away seed predators.

• It increases the temperature for germination.
