Why are keystone species important for biodiversity?

• They are the most numerous species in their ecosystems.

• They provide food for all other species.

• They help to maintain the structure and integrity of the ecosystem.

• They have no predators, ensuring their survival.

What could be a direct consequence of removing a top predator from an ecosystem?

• A decrease in the population of primary consumers.

• An increase in the diversity of plant species.

• An increase in the population of herbivores, leading to overgrazing.

How can the removal of a keystone species affect an ecosystem?

• It can increase biodiversity.

• It can lead to a more stable ecosystem.

• It has no significant effect.

• It can cause a trophic cascade and disrupt the ecosystem balance.

What is the advantage of having different shaped beaks?

• To look different from other species.

• To be able to eat the food readily available in the environment.

• To protect itself against predators.

When there is higher biodiversity...

• more organisms are likely to die because they can't adapt to environmental changes.

• there is more diversity and higher sustainability of life.

• there is less diversity.

• there is more diversity and lower sustainability of life
