(02.05 MC)

Which of the following is an example of how a biotic factor can affect the population dynamics in an ecosystem?

Lack of water during a drought causes many of the individuals in a population to die.
Seasonal temperature changes cause a species to migrate between two ecosystems.
Excessive rain and flooding cause organisms in an area to relocate.
The population of a predator increases following an increase in the population of its prey.

Zebra mussels were first discovered in North America in the Great Lakes in 1988. This invasive species eats phytoplankton and other microscopic organisms in fresh water. What would be the most likely effect if zebra mussels are introduced into a local freshwater lake?

The ecosystem would be harmed, as other phytoplankton-eating organisms would have less to eat.
The ecosystem would benefit from the increased competition for food and increased diversity.
The zebra mussels would benefit the lake, especially species higher up on the food chain.
The zebra mussels would only affect the lake if it already contained another species of mussels.

Review the survivorship curve:

A graph displaying three survivorship curves starting at the same location at a value high on the vertical axis. Curve 1 plateaus initially, then curves downward to a point on the horizontal axis. Curve 2 is a straight down right diagonal line to the same point as Curve 1. Curve 3 drops down initially and then curves and plateaus to the same point as curves 1 and 2.

Which curve(s) would you expect to represent species that have few offspring but care for them well?

1
2
3
1 and 2
