Biodiversity

What is biodiversity primarily built upon?

• Three intertwined features: ecosystem, species, and genetic diversity.

• The number of different species in an area.

• The variety of ecosystems on Earth.

• The genetic makeup of a single species.

Why is the Amazon Rainforest considered resilient to the loss of a single species?

• It has a simple ecosystem with few interdependencies.

• Its species have low genetic diversity, making them adaptable.

• It possesses a high volume of species, genetic diversity, and complex ecosystems.

• Its organisms can easily migrate to other habitats.

What defines a keystone organism in an ecosystem?

• It is the largest organism in the ecosystem.

• Many other organisms depend on it for their survival.

• It is the most common species found in the habitat.

• It is the primary producer of energy for the ecosystem.

What is the likely outcome when a keystone species like coral is weakened or killed?

• The ecosystem will quickly adapt and recover without significant changes.

• Only the species directly consuming the keystone species will be affected.

• The entire fabric of the ecosystem is threatened, as dependent species are lost.

• Other species will immediately evolve to fill the vacant role.

How is human well-being connected to biodiversity?

• Human well-being is independent of biodiversity.

• Humans are woven into biodiversity, and its loss threatens our well-being.

• Biodiversity only affects the well-being of animals, not humans.

• Humans can easily create new ecosystems to replace lost biodiversity.
