Today I will study the components of an ecosystem because I need to understand how living things depend on one another.

Catalyst

Linear vs. Exponential growth Continues to grow at faster and faster rates (J-shaped curve) Linear Growth Steady growth (straight line) This is the type of growth seen in populations

Limiting Factors Limiting Factors: biotic and abiotic factors that limit growth and reproduction Could populations continue to grow exponentially? Examples: sunlight, climate, temperature, water, food, space, competition with other organisms

Carrying Capacity Instead of growing forever, populations level out at a certain point because of limiting factors. L i m i t i n g F a c t o r s Exponential Growth Population Time

Carrying Capacity The maximum number of organisms that an environment can support is called the carrying capacity L i m i t i n g F a c t o r s Exponential Growth Carrying Capacity Population Time
