portion of the University of Florida campus in Gainesville‚ FL. Spanish moss is an atmospheric epiphyte and the Southern live oak is a hardwood tree. Some possible interactions between the two species were neutralism‚ commensalisms‚ mutualism‚ and parasitism. It was hypothesized that the relationship would be commensalism‚ with Spanish moss benefited and the Southern live oak neither benefited nor harmed. The type of symbiotic relationship was determined using two factors‚ the relative health of the

Competition- (–/– interaction) occurs when species compete for a resource in short supply example when an invasive species moves in it cause competition. Large insects defend feeding sites on cottonwood leaves by kicking and shoving smaller aphids from better sites. Predation- (+/– interaction) refers to an interaction in which

The film Alien is presented as a science fiction film. The fascination with outer space and what intelligent life out there to find are basics of the films dynamic. Digging deeper into Alien‚ it becomes much more than just a science fiction film. Alien emphasis the yonic and phallic struggle between men and women‚ along with the struggle of manmade structures and man themselves. The two struggles revolve around the two characters Ripley‚ a woman‚ and Ash a male android. The Film Alien uses the dynamics

Did you know that literally anything can change or affect an ecosystem. All kinds of relationships affect an ecosystem. An Ecosystem is a biological community of interacting organisms and their physical environment. Changes to an ecosystem can literally change and affect everything in it. Things outside of an ecosystem can affect an ecosystem. Everything connects together. Living and nonliving changes to an ecosystem can change and affect everything in it. It affects it in positive and negative ways

One density dependent limiting factor is parasitism. This describes organisms that live off a host that can easily pass from one organism to another because they are close together. Parasites are more likely to spread through a population if the population density is high. 1. One density independent limiting factor is natural disasters‚ such as fires‚ floods‚ and tornadoes‚ each of which can wipe out a significant number of a population. 2. Another density dependent limiting factor is competition
