When there is higher biodiversity

• more organisms are likely to die because they can't adapt to environmental changes.
• there is less diversity.
• there is more diversity and higher sustainability of life.
• there is more diversity and lower sustainability of life

A small marine area has phytoplankton as its only producer.  Should the marine biologist be concerned about this ecosystem?

• No the fish do not need the phytoplanton. Since there are so many fish, there is high biodiversity.
• Yes, this ecosystem has low biodiversity.  Without a producer the herbivores will die out leaving no food.
• Yes, this system has high biodiversity; however the fish can adapt and get food from another source.
• Yes, the fish will overate to get all of the phytoplankton that is left, then they will die.

How do biodiversity and sustainability work together?

• The lower the biodiversity the greater the sustainability.
• The higher the biodiversity, the less sustainable the ecosystem
• The higher the biodiversity, the greater the sustainability.
• Biodiversity has nothing to do with sustainability.
