The video explains the symbiotic relationship between Clark's nutcracker and pine trees in Yellowstone. The nutcracker eats pine nuts, which are seeds of pine trees, and helps in their dispersal by hiding them across the park. This dispersal is crucial for the growth of new trees. During winter, nutcrackers rely on these stored seeds for survival, while some seeds remain to grow into new trees. This mutual dependence highlights the ecological balance in Yellowstone.

What is the primary diet of Clark's nutcracker?

• Insects

• Pine nuts

• Berries

• Small mammals

Why is seed dispersal important for pine trees?

• It helps in pollination

• It prevents overcrowding near the parent tree

• It attracts more birds

• It increases the tree's height

How does Clark's nutcracker prepare for winter?

• By migrating to warmer areas

• By hibernating

• By storing pine nuts under stones

• By building a nest

Approximately how many pine nuts does a single nutcracker disperse?

• 30,000

• 40,000

• 20,000

• 10,000

What is the relationship between nutcrackers and pine trees?

• Nutcrackers harm pine trees

• Pine trees provide shelter for nutcrackers

• Nutcrackers only eat pine trees

• They have a mutual dependency
