Question

Burmese pythons (Python molurus bivittatus) are constricting snakes that can reach enormous sizes (up to 7 meters in length). They are native to Southeast Asia but were released into southern Florida from the pet trade. Many other snakes occur naturally in this area. Are the introduced pythons a problem?

Researchers hypothesize that the severe winter of 2010 caused the decline in the number of pythons encountered that year. Is cold weather typically a density-dependent factor or a density-independent factor? Explain the difference.

Accepted Answer

Hello everyone here. We have a question that says flood is a blank factor, whereas competition is a blank factor. So density independent factors change per capita growth rate independently of population density. So the number of people or organisms does not matter if its density independent if its density dependent, it changes per capita growth rate. So it depends how many organisms are in a habitat or in an area. So floods are independent because floods happen. No matter how many there are. Competition, however, is a dependent factor because you're gonna have higher competition, the more animals there are. So our answer here is B density independent, density dependent. Thank you for watching. Bye.
