How could wildfire immediately impact competition in a forest ecosystem?

Competition would increase. Wildfire would increase the scarcity of resources, causing individuals to compete at higher rates.

Competition would decrease. Wildfire would decrease the number of individuals competing for resources, making more resources available per individual.

Competition would remain the same. Wildfire would increase the scarcity of resources and decrease individuals competing, effectively balancing each other out.

Competition would decrease. Many ecosystems rely on wildfire to restore nutrients and germinate seeds; therefore, wildfire would increase resources available, lowering competition.

Two prides of lions compete with one another for the same prey (antelope). Which scenario would cause a decrease in competition?

A. A disease kills individuals from the lion population.

B. Wildfire kills many antelope and some lions.

C. An invasive species outcompetes and replaces antelope.

How do high temperatures affect corals?

A. corals become more susceptible to disease
B. corals become more colorful

D. corals collect more zooxanthellae

A. corals become more susceptible to disease

Jumping worms affect populations in forest ecosystems by directly competing with native

A. primary consumers.
B. secondary consumers.
C. decomposers.
D. producers.

C. decomposers.

In order to explain how changes to physical components of an ecosystem affect populations, you must use data from observations and investigations. These data are also known as

empirical evidence.

C. An invasive species outcompetes and replaces antelope.
