Unit 2 Pre-test

Which of the following is a characteristic of generalist species?

• Narrow niche

• Wide niche

• High extinction risk

• Specialized diet

Which of the following is a characteristic of specialist species?

• High adaptability

• Narrow niche

• Can thrive in many conditions

• Broad niche

Which type of species typically produces many offspring with little parental care?

• K-selected

• R-selected

• Generalist

• Specialist

Elephants, which reproduce slowly and invest heavily in offspring, are an example of:

• K-selected
• R-selected
• Specialist
• Generalist

Which survivorship curve represents species with high mortality early in life?

• Type I

• Type IV

• Type III

• Type II

Which survivorship curve represents humans and elephants?

• Type II

• Type IV

• Type I

• Type III

Carrying capacity (K) refers to:

• Average number of offspring per female

• Rate of exponential growth

• Maximum population size the environment can support

• Minimum viable population

When a population exceeds carrying capacity, it often leads to:

• Stable equilibrium

• Population crash

• No change

• Sustained growth

In exponential growth, the population increases:

• At a constant rate

• Without limit

• Proportionally to its size

• At a decreasing rate

The logistic growth model includes:

• Density independence

• Carrying capacity

• No limiting factors

• Unrestricted growth
