BIO 182 EXAM 3 ACTUAL UPDATED
Exam Questions and CORRECT Answers
The project reached its carrying capacity in ______ - CORRECT ANSWER - False
During 1995-2002, the number of births likely exceeded the number of deaths. - CORRECT
ANSWER - True
Between 1996 and 1999, the death rate in the population could have exceeded the birth rate if
immigration from other populations increased greatly. - CORRECT ANSWER - True
Between 1988 and 2007, the rate of death could have exceeded the rates of birth and immigration
if emigration to other populations increased steadily. - CORRECT ANSWER - False
The growth of the population between 1998 and 2007 can be adequately described by an
exponential model. - CORRECT ANSWER - True
Competing Carp - CORRECT ANSWER - False
An increase in the number of species 2 likely contributed to the decline in species 1. -
CORRECT ANSWER - True
An increase in competition within species likely contributed to the decline in species 1. -
CORRECT ANSWER - True
A mutation in species 1 that causes its fundamental niche to diverge from the fundamental niche
of species 2 could increase the fitness of species 1. - CORRECT ANSWER - True
Both species will likely coexist in a lake that has cool water but a low concentration of oxygen. -
CORRECT ANSWER - False
, Since the brown tree snake is a keystone species in Guam, it must also be a keystone species in
Australia. - CORRECT ANSWER - False
Native predators of birds on Guam likely decreased in abundance after brown tree snakes arrived
- CORRECT ANSWER - True
If birds on Guam usually disperse seeds, brown tree snakes likely had a negative indirect effect
on plants. - CORRECT ANSWER - True
Since more prey and fewer predators occur on Guam than in Australia, the density of brown tree
snakes in Guam likely exceeds the density in Australia. - CORRECT ANSWER - True
If some of the extinct species of lizards used to eat bird eggs, brown tree snakes had a positive
direct effect, though still exhibits a negative indirect effect, on birds. - CORRECT
ANSWER - False
All of the nitrogen in fertilizers will end up in bodies of water. - CORRECT ANSWER -
False
If the supply of nitrogen limits the growth of plants, emissions from burning fossil fuels should
lead to more biomass of plants. - CORRECT ANSWER - True
A teleconnection occurs when nitrogen introduced as fertilizer ends up causing algae to bloom in
the ocean. - CORRECT ANSWER - True
Negative feedback would occur if emissions of fossil fuel increase the rate of nitrification by
bacteria. - CORRECT ANSWER - False
Positive feedback occurs when nitrification by bacteria causes the population of bacteria to grow.
- CORRECT ANSWER - True
