Question
Chapter 20, Problem 10SQ
Summary Introduction
To determine:
Movement corridors.
Introduction:
Landscape has an important feature where habitats have been acutely fragmented. The places in which extremely heavy human impact is present, the artificial corridors are constructed. Corridors help in sustaining of population by promoting the dispersal of individuals.

In landscape ecology, the matrix is the area surrounding a habitat patch. The matrix can affect a species living in the habitat patch by altering:
O A. Dispersal between patches

At any point in time, a number of environmental objectives must be met with a limited amount of economic resources. This means that once an environmental problem is identified, they have to be prioritized. In general, this is done using scientific valuation of the relative risk to human health and the ecology of a given environmental hazard - a procedure known as:
A. Biodiversity
B. Public Goods
C. Risk Assessment
D. Profit maximization
Which of the following best describes a keystone species?
a. An organism, whose introduction causes or is likely to cause environmental harm
b. An organism, who if removed, the entire ecosystem changes.
c. Can signal a change in the biological condition of a particular ecosystem and diagnose the health of that ecosystem
d. Can indirectly protect several other species in the same habitat
