Chapter 1, Problem 24A

Summary Introduction

To determine:

The seabird colony that has the access to the highest fish biomass upto the depth of 40 meters.

Introduction:

The prime driver of coral reef ecosystem is the fish biomass. It is highly sensitive to human activities, like fishing. Fish biomass estimation, its spatial distribution, and potential of recovery help in analysing reef status.

Explanation of Solution

In the graph, relative fish biomass is given at five water depths, 10 m, 20 m, 30 m, 40 m, and 50 m. The seabird colonies used to analyse the relative fish biomass are Chisik, Kachemak, and Barrens. From the given graph, it is clear that at 40 m depth the highest fish biomass is of Kachemak seabird. The lowest fish biomass at this depth is of chisik.
