Population Dynamics 2026

A population is 

• a group of communities that exist in different places
• a group of organisms of one species that lives in the same area at the same time
• a group of people that populate one place at the same time on different planets

Carrying Capacity is

• the capacity of what one person can carry per day 
• how many animals you have in your daily bag limit at the end of the year
• wildebeest at a watering hole with zebras
• the maximum number of individuals that the environment can support
