BIO 1001 COMMUNITY & ECOSYSTEM ECOLOGY & CON-SERVATION OF
BIODIVERSITY EXAM (VERIFIED & CORRECTLY SOLVED)
In biology, an arms race occurs when .
Select one:
a. predators become dominant over their prey species leading to the local extinction of
the prey
b. a new species evolves into two separate species
c. there is a repeating cycle of reciprocal adaptation
d. a prey species adapts and is able to coexist with its predators
e. a new niche is created because of interactions between species
The main goal of sustainable development is to:
Select one:
a. re-evaluate and re-implement management plans over time.
b. use only natural resources in the construction of new buildings.
c. involve more countries in conservation efforts.
d. use natural resources such that they do not decline over time.
Periwinkle snails, which feed on various types of algae, are thought to be keystone
species of rocky northeastern Atlantic shores. This is because
Select one:
a. The action of periwinkles made one type of algae less dominant, which allowed other
algae populations to continue.
b. Periwinles eliminated all of the less-dominant algae species
c. Periwinkles eliminated the dominant algae entirely.
d. Periwinkles eliminated all algae and died out.
Which of the following is one of the criteria used to define an area as a conservation
“hotspot”?
Select one:
a. A high species diversity that ranks in the top 70% worldwide.
b. Over 70% of the plant species are endemic.
c. Lost at least 70% of their primary vegetation.
Which of the following terms describes the community interaction where one organism
makes the environment more suitable for another organism?
Select one:
a. facilitation
b. commensalism
