Symbiotic Relationships in Desert
Transcript of Symbiotic Relationships in Desert
Mammalian predators are mammals such as badgers, bobcats and coyotes.
Reptilian predators are reptiles like Mojave rattlesnakes, Black-collared lizards and Mountain Kingsnakes.
Avian predators are birds like Red-tailed hawks, Golden eagles and Great-horned owls. What is Symbiosis? SYMBIOSIS refers to the long-term interaction between members of two different species that live together in a close association. There are 3 types of symbiotic relationships: MUTUALISM, COMMENSALISM, and PARASITISM. Mutualism in the Desert MUTUALISM occurs when both organisms benefit from each other. it can further be divided into 3 categories: TROPHIC, DISPERSIVE, and DEFENSIVE
Trohic mutualism happens when both organisms benefit from the resources.
Dispersive mutualism is when one organism benefits from resources while the other recieves services.
Defensive mutualism occurs when both organisms benefit from services. Example of Mutualism Here is an example of mutualism in deserts: The Phainopepla bird ingests mistletoe berries and disperses its seeds through droppings. Like this, mistletoe plants provide food for the Phainopepla birds while the birds help them reproduce. This is an example of a dispersive mutualism. This process is necessary for the Phainopepla since they depend on the mistletoe berries for food. On the other hand, the mistletoe might not be able to reporduce without the Phainopepla birds. A Phainopepla bird eating mistletoe berries Parasitism Commensalism COMMENSALISM refers to the process in which only one organism benefits while the other is neither helped nor harmed. This may also be put into 3 different groups: PHORESY, INQUILINISM, and METABIOSIS.
Phoresy commensalism is when one organism uses the other for transportation.
Inquilinism commensalism happens when one organism uses the other for shelter.
Metabiosis commensalism occurs as one organism creates a suitable environment for the other. Citations www.digital-desert.com/wildlife/predators.html

This aids the cactus wren but does not harm the cacti and this is an inquilinism commensalism. Without this relationship, the young cactus wren could be easily wiped out by predators. PARASITISM happens when one organism benefits from the process while the other one is harmed or killed. The organism that benefits is the PARASITE and the one that is harmed is the HOST. There are 2 kinds of parasitism: BIOTROPHIC, and NECROTROPHIC.
Biotrophic parasitism is when the host is harmed but not killed
Necrotrophic parasitism is when the host is killed. In the Mojave Desert of the United States, wasps often lay their eggs nearby the ones laid by the preying mantis. When the wasps' eggs hatch into larvae (the babies), they will feed on the preying mantis' eggs. This interaction is important because without the eggs of the preying mantis, the larvae of the wasps would not have anything to eat and might not survive. Thank You By: Hira and Letitia
