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 phytoplankton. Since there are so many fish, there is high biodiversity.

• Yes, this system has high biodiversity; however the fish can adapt and get food from another source.

• Yes, this ecosystem has low biodiversity. Without a producer the herbivores will die out leaving no food.

• 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 higher the biodiversity, the greater the sustainability.

• The lower the biodiversity the greater the sustainability.

• The higher the biodiversity, the less sustainable the ecosystem.

• Biodiversity has nothing to do with sustainability.

Why is biodiversity in an ecosystem so important?

• Because it can help humans where to determine good places to develop farm land.

• Because places that have a healthy biodiversity are unaffected by major disturbances.

• Because having a high biodiversity allows for fewer opportunities of competition for similar resources.

• Because having a high biodiversity allows ecosystems to withstand disturbances (major changes).
