1. 4/14/10Ecosystems and Limiting Factors#8 Entry Task: A milkweed bug population starts with only one female and one male. There’s plenty of food and everything else the bugs need to thrive. How big would the milkweed-bug population be after 1 year? Here is some information to help you: LT: I will define my ecosystem, identify the producers, and learn how limiting factors affect populations. Today’s Plan: -Limiting factors -Computer Lab

3. 4/14/10Ecosystems and Limiting Factors#8 31,875,000,000 milkweed bugs! About 32 billion! LT: I will define my ecosystem, identify the producers, and learn how limiting factors affect populations. Today’s Plan: -Limiting factors -Computer Lab

5. 4/14/10Ecosystems and Limiting Factors#8 The reproductive potential of 2 milkweed bugs in one year would be about 32 billion, but the population never reaches that potential. Limiting factors prevent populations from reaching their reproductive potential. LT: I will define my ecosystem, identify the producers, and learn how limiting factors affect populations.
