Connecting the Dots: Sea Turtles and Ecosystem Balance

The video explains the crucial role of sea turtles as a keystone species in marine ecosystems. Sea turtles help maintain healthy seagrass beds and control jellyfish populations, which supports marine biodiversity and human reliance on oceans. They are part of the marine food chain and have mutualistic relationships with other species. The video also highlights the threat of plastic pollution in oceans.

Why are sea turtles considered a keystone species?

• They are essential for the survival of other species in their ecosystem.

• They can swim at super speeds.

• They are the largest marine animals.

• They provide food for humans.

How do sea turtles help maintain healthy seagrass beds?

• By protecting them from predators.

• By planting new seagrass seeds.

• By eating seagrass, which promotes new growth.

• By fertilizing them with their waste.

What is the impact of sea turtles on jellyfish populations?

• They increase jellyfish numbers.

• They avoid jellyfish entirely.

• They have no impact on jellyfish.

• They help control jellyfish populations.

What is a mutualistic relationship in the context of sea turtles?

• A relationship where sea turtles dominate other species.

• A relationship where sea turtles and other species benefit each other.

• A relationship where sea turtles compete with other species.

• A relationship where sea turtles are harmed by other species.

Why is plastic a problem in the ocean?

• It is a natural part of the ocean environment.

• It disrupts marine ecosystems and harms wildlife.

• It helps clean the ocean.

• It provides food for marine animals.
