Angie visited 3 different ecosystems to collect specimens. She visited a grassy area in a tundra, and a pond and a woody area in a Temperate deciduous forest. She collected 20 different types of species from the tundra, 64 different types of species from the the pond and 98 different types of species from the woody area in the forest. Which ecosystem is the MOST sustainable?

• grassy area in a tundra

• pond in a temperate deciduous forest

• woody area in a temperate deciduous forest

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

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

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
