Multiple Select

What are the three main parts of Biodiversity?

(Check all 3 that apply)

• Genetic

• High Risk

• Ecological

• Species

Poll

True or False: higher species diversity allows for a more sustainable ecosystem?

• TRUE

• FALSE

Multiple Choice

Four students plan on creating an ecosystem in an aquarium. Their plans are listed. Each include soil and water.

Which ecosystem is most likely to be sustainable?

Multiple Choice

An ecosystem that is not sustainable can break down when a natural disaster occurs. This can lead to organisms in the ecosystem either leaving the area or dying off.

Increased biodiversity results in a more sustainable ecosystem because -

• a greater number of plant species means that there is less barren land

• a greater variety of species present allows more organisms to adapt after changes occur

• the transition area between two ecosystems is narrower

• there are fewer species to be affected by environmental stresses

Multiple Choice

Which ecosystem would be more likely to survive if a disease killed all the grasses?

• The forest ecosystem - because most of the organisms can eat other organisms

• The forest ecosystem - because it has three top predators

• The grassland ecosystem - because several predators compete for food

• The grassland ecosystem - because it has several herbivores

Multiple Choice

When Charles Darwin visited the Galapagos Islands in the 1800s, he observed many types of organisms that were similar but lived on different islands. The four species of mockingbirds found on the Galapagos Islands are shown. Each species lives on a different island.

These species are very similar, but the Hood Mockingbird has a longer beak than the other three species. Which of the following explains the difference?

• The Hood mockingbird needs a longer beak for defense against predators.

• The Hood mockingbird originated from a different type of bird than the others.

• The Hood mockingbird's longer beak is an adaptation to the food available in the bird's habitat.

• The Hood mockingbird's beak stretched to reach its food, and the longer beak was passed down to its offspring.
