Chapter 54, Problem 2IQ
Summary Introduction
To determine: The increase in the population of smaller or larger size species under resource abundance.
Introduction: Population density is the number of a specific type of individuals living in a specified area for a given period of time. The population density can be calculated for plants, microbes, humans, domestic animals, and others.

Please answer questions from 1 to 10
1) compare species diversity and genetic diversity
2) list several reasons to value biodiversity
3) how does the green house effect occur?
4) identify the primary causes of modern species extinction
5) describe how pesticides, such as DDT, undergo the process of biological magnification
6) choose a species that might be affected by global warming, and predict how that species might be affected
7) contrast conservation biology with restoration biology
8) explain why reserves protect biodiversity
9) explain causes and affects of acid rain
10) give an account of the factors that threaten biodiversity
Q10. An ecologist wants to know if diversity in a forest system is likely to decrease when an invasive species
is introduced. This invasive species is a fast-growing annual plant that grows on oak trees and kills them.
The invasive species can only survive on living oak trees. The ecologist has the original model from this lab
and another version of the model which includes transitions that involve the invasive species.
To answer the research question, the ecologist should compare species diversity generated by the original
model to diversity generated by which model described below?
A model in which oak has a positive transition rate to the invasive and the invasive has a positive transition to
grass.
A model in which oak has a positive transition rate to the invasive and the invasive has a positive transition to
oak.
A model in which the invasive has a positive transition rate to oak and oak has a positive transition to grass.

- SUBJECT : Biology - Ecology How would you describe the slope of a rank-abundance curve that vary with increasing species evenness?arrow_forwardDetermine if each statement is correct or incorrect: 1. Ecosystems with fewer numbers of species tend to be less stable. 2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem. 3. More species mean more niche separation. 4. Species with a low resistance will also have low resilience. 5. Disturbances to ecosystems can be both naturally occurring and human caused. 6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive. 7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.arrow_forwardQuestion 2 Connectivity decreases when Question 2 options: A) dispersal is frequent.
