Question
Chapter 53.5, Problem 1CC
Summary Introduction
To describe: The three features of habitat patches that can affect the population density, emigration rate, and immigration rate.
Concept introduction: The “habitat patch” is any distinct area with a specific shape and configuration and is used by an organism at a specific time for living, breeding or obtaining further
The available resource in any habitat patch affects the local population density and the rates of emigration and immigration. Below mentioned are the three attributes of habitat:
- Size
- Quality
- Isolation of patches.
