Populations
How might establishing wildlife corridors impact ecological balance?
They may facilitate gene flow between animal populations.
They could increase habitat fragmentation for certain species.
Might result in a reduction of ecosystem services provided by wildlife habitats.
Could potentially decrease biodiversity by isolating populations.
In terms of population dynamics, what is likely to occur if resource availability in an environment declines?
The carrying capacity for local populations decreases.
Migration patterns become less predictable.
Global temperature progressively rises.
Species mutation rates increase.
What could be a trade-off associated with implementing strict pollution control policies?
Possible increase in production costs for industries.
Improved public health due to better air quality.
Reduction in the emission of greenhouse gases.
Decreased instances of acid rain affecting ecosystems.
What is the consequence of a population crash?
Elimination of competition
Exponential growth of the population
Increase in carrying capacity
Rapid decrease in population size
Which of the following factors can contribute to an increase in carrying capacity for a population?
Increase in competition
Expansion of available habitat
Decreased genetic variation
Scarce resources
What happens when a population exceeds its carrying capacity?
Resource depletion occurs.
Population growth increases exponentially.
Immigration rates surpass emigration rates.
The birth rate becomes zero.
In ecological terms what does "K" represent?
The Biome Type
The Carrying Capacity
The Biodiversity Index
The Climate Change Factor

What term is used to describe a rapid decrease in population size due to a lack of available resources?
Population overshoot
Die-off
Carrying capacity
Exponential growth
Which scenario illustrates the principle of competitive exclusion in relation to carrying capacity?
Seasonal fluctuations in food supply cause regular but temporary exceedance of an environment's carrying capacity.
A keystone species increases overall ecosystem stability by maintaining diversity and carrying capacities across trophic levels.
A species expands its range into new territories when its population size exceeds the local carrying capacity.
Two species with identical ecological niches cannot coexist indefinitely; one will outcompete the other for limited resources.
What is the term for the situation when resources are unlimited, and population size grows without constraints?
Carrying capacity
Die-off
Exponential growth
Population overshoot
