Chapter 56, Problem 7IQ
(a)
Summary Introduction
Toanalyze: The reason for the greatest species richness at the intermediate level of productivity.
Introduction: The term species richness can be defined as several different species found in an area.
(b)
Summary Introduction
Toanalyze: The reason for the highest number of species found in structurally complex areas.
Introduction: The number of species found on the earth is known as biodiversity. The different type of species needsa different environment for survival.
(c)
Summary Introduction
Toanalyze: The reason for the presence of more species in the area with less variation in temperature.
Introduction: The species richness can be calculated by the number of species found per unit area.
