Unit 3 Key Vocab Practice

What is the definition of 'Generalist'?

• A species with broad habitat and food requirements.

• A species that only eats plants.

• A species that lives only in water.

• A species with very specific food needs.

What is the definition of 'Specialist'?

• A species with a narrow food or habitat requirements.

• A species that can survive in a wide range of environments.

• An organism that produces its own food through photosynthesis.

• A species that migrates seasonally to find food.

What is the definition of 'r-selected species'?

• Species that produce many offspring with little or no parental care, resulting in rapid pop. growth rates, carrying capacity overshoot, and dieback.

• Species that produce few offspring with high parental care, resulting in stable population sizes.

• Species that are always at risk of extinction due to low reproductive rates.

• Species that only reproduce once in their lifetime and then die.

What is the definition of 'K-selected species'?

• Species that produce few offspring with high parental care, resulting in slow pop. growth and stable population sizes near carrying capacity.

• Species that produce many offspring with little parental care, resulting in rapid population growth and fluctuating population sizes.

• Species that are only found in aquatic environments and have no parental care.

• Species that reproduce only once in their lifetime and then die.

What is the definition of 'Biotic potential'?

• The maximum reproductive rate of a population under ideal conditions (unlimited resources).

• The total number of species in an ecosystem.

• The amount of energy transferred between trophic levels.

• The minimum population size required for survival.

What is the definition of 'Type I Survivorship'?

• A curve where survivorship is high early in life and declines sharply in old age.

• A curve where survivorship is low early in life and increases with age.

• A curve where survivorship remains constant throughout life.

• A curve where mortality is highest in the middle years of life.

What is the definition of 'Type II Survivorship'?

• A curve with a consistent decline in survivorship throughout the lifespan.

• A curve with high survivorship early in life and low survivorship late in life.

• A curve with low survivorship early in life and high survivorship late in life.

• A curve that shows no decline in survivorship throughout the lifespan.

What is the definition of 'Type III Survivorship'?

• High early mortality but lower mortality in middle and late life.

• Low early mortality and high mortality in late life.

• Constant mortality rate throughout life.

• High survivorship in early life and low survivorship in late life.

What is the term for when a population temporarily exceeds carrying capacity, followed by a sharp decline?

• Overshoot & dieback/die-off

• Population equilibrium

• Carrying capacity stabilization

• Sustainable growth
