Biotic factors are …… between organisms

What is Competitive exclusion principal

• Both species will go extinct w/ different niches

• One species will go extinct w/ same niches

• One species will go extinct w/ different niches

• Both species will go extinct w/ same niches

Niche... Is when different species share a niche by using/consuming different sections

Difference between fundamental & realized niche

• Fundamental:actually survive & realized: potentially survive

• Fundamental: no survival or death & Realized: optimal survival

• Fundamental: potentially survive & Realized: actually survive

Calculate FCR:

• GPP - Respiration

• (amount converted/total) x 100

• (total #) x (total #2) / # previously captured in 2nd

• Food fed/consumed by animal / body mass gained

What gershmel diagram do-we not need to know

• Taiga

• Tropic rainforest
