• Exponential Growth

• Logistic Growth

• Stable Growth

• Strategic Growth

NGSS.HS-LS2-6

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

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
