100
When individuals of different species compete for the same resource in an ecosystem.
What is interspecific competition
100
A group of individuals of one species.
What is a population.
100
The three processes that change the size of populations.
What are birth, death, and movement.
200
A non-native species with a tendency to spread and harm its new environment.
What is an invasive species.
200
The two species of barnacles observed in the experiment.
What are Chthamalus stellatus and Balanus balanoides
200
Rooted or fixed organisms that grow by repeated production of modules.
What is a modular organism.
200
Species that, post-juvenile years, swims thousands of miles from their birthplace, but returns years later to reproduce.
What is the Pacific Salmon
300
An invasive species available for purchase in the U.S. that costs the government $600,000+ annually to control.
What is Eurasian watermilfoil.
300
That the absence in the lower zone of adults of Chthamalus was due to interspecific competition with Balanus for space.

Mass directional movement of large numbers of a species from one location to another.
What is migration.
300
Process that consists of birth, pre-reproductive period, reproduction, post-reproductive period, and death.
What is the life cycle.
400
1. allowing any and all new species 2. allowing no new species 3. prescreening species for invasive likelihood and only allow low-risk species to be traded.
