Biodiversity and Sustainability

Anastayjia visited 3 different ecosystems to collect specimens. She visited a grassy area in a tundra and woody area in a Temperate deciduous forest. She collected 20 different types of species from the tundra and 98 different types of species from the forest. Which ecosystem is the MOST sustainable?

• Tundra

• Desert

• Temperate deciduous forest

• Rainforest

What is true about sustainability?

• Having a small number of species increases biodiversity

• Sustainability is how organisms change over time

• Sustainability is how much rainfall and sunlight an ecosystem receives

• The more different types of species you have (biodiversity) the better an ecosystem can sustain itself

Biodiversity means..

• The variety of life in an ecosystem

• How an ecosystem changes over time

• Differences among humans

• Diversity of a select few species in a deserted area

A certain area of the Indian ocean is expected to dry up and become a desert over thousands of years. What will happen to the sustainability of this ocean?

• Sustainability would increase because the number of species would increase

• Sustainability would remain the same

• Sustainability would decrease because the number of species would decrease

• Not enough information is given

What is false about biodiversity

• More biodiversity makes it least likely for a species to survive a disturbance such as a Tsunami

• More biodiversity allows species to survive a disturbance such as a hurricane

• As biodiversity increases sustainability increases

• Genetic biodiversity is what makes us look and act different

A hurricane hit a tundra and a forest. A tundra is less biodiverse than the forest. Which biome would be impacted the most?

• The forest because it has more species and it wouldn't be able to sustain itself as well as the tundra

• They would be impacted the same

• The forest because it has more producers

• The tundra because it has less species and it wouldn't be able to sustain itself as well as the forest

When biodiversity increases

• Sustainability decreases

• Sustainability remains the same

• Sustainability also increases

• Sustainability becomes greater by 2
