Biodiversity and Sustainability Unit 2

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

What is false about biodiversity

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

• As biodiversity increases sustainability increases

• Genetic biodiversity is what makes us look and act different
