MYP Biology Warm-upWarm-up:

Create a possible quiz question related to carrying capacity, limiting factors, or population growth. Use your notes to help. Make sure you identify the correct answer.

Quiz a friend and see if they answer correctly!

Ecosystem VocabularyAdd to your notes:

Limiting Factor - an environmental factor that controls the growth or distribution of a population.

Density-dependent factors - limiting factors that affect denser populations more than less crowded ones.

Density-independent factors - limiting factors that affect populations regardless of density.

Limiting Factors Card SortWork with your partner to sort the cards into density-dependent and density- independent factors. Be sure you can support your decisions. After class discussion, record the factors in a T-chart in your notebook:

Density-dependentFactors

Density-independentFactors
