4
Which type of ecological succession is represented by the picture?
Secondary Succession
Primary Succession
5
Overexploitation of a fish population occurs when
harvest rate > reproductive rate
harvesting does not occur
harvest rate < reproductive rate
the harvest rate = reproductive rate

True
False
7
What are keystone species?
if removed would cause no harm and little effect to the food web
The apex predators of the food web
The primary producers of the food web
if removed would cause significant negative impact on the ecosystem

13
The carrying capacity is
amount of species that can survive in one area

14
What is the 10% rule?
10% of the world needs to recycle
10% of energy is dissipated as heat
10% of the U.S. budget goes toward the environment
