Sect 2.13-2.16 Population Characteristics/Movement

Front

What is migration?

Back

Migration is the movement of entire populations at predictable times from an area lacking resources to an area having resources.

How many bacteria will there be after one hour if they double every 20 minutes?

Back

Front

What describes a healthy population?

What is nomadism?

Back

Nomadism is a regular, wide-ranging, random wandering behavior.

Front

What is dispersal?

Back

Dispersal is the movement of offspring away from the parents.

Front

What is the difference between migration and dispersal?

Back

Migration involves the movement of entire populations, while dispersal refers specifically to the movement of offspring away from their parents.

Front

What factors can influence population movement?

Back

Factors include resource availability, environmental conditions, and social behaviors.

Front

What is a limiting factor in population dynamics?

Back

A limiting factor is a resource or condition that limits the growth, abundance, or distribution of a population.

Front

What is the significance of parental care in population health?

Back

Parental care can lead to higher survival rates for offspring, contributing to a healthier population.

Front

How does population density affect migration patterns?

Back

High population density can lead to increased competition for resources, prompting migration to areas with more resources.
