Population Ecology Graphs and Carrying Capacity

A population is...

• All members of one species in one area

• All members of all species that live in one area

• All of the living and nonliving things in an area

• None of these

Which factor is a density-dependent limiting factor on the population of a species?

• seasonal variation

• natural disasters

• unusual weather

• predation

Population increases at a constant rate over time.

• Exponential Growth

• Logistic Growth

• Stable Growth

• Strategic Growth

NGSS.HS-LS4-2

A graph that shows the number or proportion of individuals surviving to each age for a given species or group.

• survivorship curve

• exponential

• linear

• logistic

Tracks organisms that tend to live long lives (low death rate and high survivorship rate); toward the end of their life expectancies, however, there is a dramatic increase in the death rate.

• Type I

• Type II

• Type III

• Type IV

NGSS.HS-LS2-2

Describes organisms with a high death rate (or low survivorship rate) immediately following birth. Examples include bacteria, fishes, and invertebrates.

• Type I

• Type II

• Type III

• Type IV

These organisms occupy stable environments, are larger in size and have longer life expectancies. They produce, during their life spans, fewer offspring, but place a greater investment in each.

• k-strategist

• r-strategist

• m-strategist

• s-strategist

• Exponential Growth
• Stable Growth
• Declining Growth
