INTRODUCTION TO BIOLOGY - C190 UNIT 9 TEST
Nauru has relatively few native plants and animals. Native animals include birds,
insects, a few crabs, but no mammals. Most of the plant species on the island are
domesticated plants such as the coconut palm. The climate of Nauru is warm year-
round with variable precipitation.
Match the example to the correct ecological level.

Coconut palms are
Population
The topsoil in the island has mostly been lost, which interferes with plant growth.
Topsoil contains essential plant nutrients, such as nitrogen and potassium.
What is the source of a plant's nitrogen?
NO3- comes from the soil
Which type of organisms are able to convert nitrogen into a usable form for plants?
Bacteria
Nutrients are taken up by corn, corn is fed to chicken, and chicken feces with excess
nutrients runs off into a river.
Is this a potential pathway for the cycling of nutrients from fertilizers?
