  2. Separate out the 4 big cards.
  3. Sort the remaining small cards into each of the 4 categories.

Provisioning Services

These services provide raw materials for humans to survive

Regulating Services

These services help provide security against natural disasters and that natural resources are available to all.

Supporting Services These make it possible for ecosystems to keep life going

Cultural Services

These are important to the social fabric of human societies

Bird Island - Our investigation study

A group of scientists recently returned from surveying Bird Island, a remote island in the Atlantic Ocean.

​

This island is inhabited by people.

​

The scientists identified six species of birds living on the island.

​

Here is a map they created after surveying the island (on your table too). Each population of birds is shown as a unique symbol on the map and indicates a sampling site.

​

53 of 111

Looking at the map, how many ecoregions are on Bird Island?

54 of 111

How could you compare one ecoregion to another?

55 of 111

Purpose of this investigation

Typically, ecosystems with high species abundance and high species richness are those that are complex enough to withstand a disturbance event.

​

​

Goal: To determine the species abundance and richness in each ecoregion to analyze which ecoregion is most likely to survive a disturbance.

You will work in groups of 6 people

56 of 111

Procedure

  1. Use the map to fill out your entire data table
  2. For the species that you are assigned, create a bar graph to show species abundance in each of the ecoregions
  3. For the ecoregion that you are assigned, create a bar graph to show species abundance within your ecoregion

Multiple food sources prevents a food chain collapse:

​

The ravens don’t lose all their food sources if the tree frogs are wiped out by a virus.

65 of 111

Multiple predators control population sizes:

​

The deer population is held in check by the coyotes, even if the mountain lions are hunted to local extinction. This protects the trees (deer’s food) from being overeaten.

Multiple species performing the same service ensures that the service isn’t interrupted by extreme events.
