Limiting Factors
Sophisticated
Accurately defined.
Includes 5 density-dependent factors and 8 density-independent factors.
Mastery
Accurately defined.
Includes 4 density-dependent factors and 6 density-independent factors.
Developing
Accurately defined.
Includes 2-3 density-dependent factors and 3-5 density-independent factors.
Beginning
May or may not be accurately defined.
Includes 1-2 density-dependent factors and 1-2 density-independent factors.
Carrying Capacity
Sophisticated
Accurately defined.
Graph is clear & accurate, showing growth rate increasing, growth rate slowing, and growth rate stopping with population stabilizing.
Accurately explains why the population line "wiggles" over and under the Carrying Capacity line.
These topics are accurately labeled and explained on the graph:
- lag phase
- exponential growth phase
- deceleration phase
- stable equilibrium phase
Mastery
Accurately defined.
Graph is clear & accurate, showing growth rate increasing, growth rate slowing, and growth rate stopping with population stabilizing.
Accurately explains why the population line "wiggles" over and under the Carrying Capacity line.
Developing
Accurately defined.
Graph is clear & accurate, showing TWO of these:
-growth rate increasing,
- growth rate slowing
- growth rate stopping with
population stabilizing.
Beginning
Incompletely or inaccurately defined.
Graph is unclear, incomplete, and/or has mistakes.
Graph shows ONE of these accurately:
-growth rate increasing,
- growth rate slowing
- growth rate stopping with
population stabilizing.
