# examples of symbiotic relationships

From Wikipedia

Inverse relationship

An inverse or negative relationship is a mathematical relationship in which one variable, say y, decreases as another, say x, increases. For a linear (straight-line) relation, this can be expressed as y = a-bx, where -b is a constant value less than zero and a is a constant. For example, there is an inverse relationship between education and unemployment â€” that is, as education increases, the rate of unemployment decreases

Inverse relationships and their counterpart, direct relationships, are widely used in thephysical sciences to describe the relationship between two variables in an equation.

In economic graphing, two variables are said to have an inverse relationship if the graph line slopes downward to the right.

Question:I need 1 example of Mutalism Symbiotic relationship. 1 example of Commensalism Symbiotic relationship, 1 example of parasitism symbiotic relationship, and 2 examples of predatation symbiotic relationships. Any one of these will be great! Thank you so much!

Answers:One example of a mutualism symbiotic relationship, would be the existence of bacteria in the human gut. The human gets the benefit of digesting food more efficiently, while the bacteria gets food and shelter.

Question:I need this b-4 Nov. 13 okay so hurry! plz! Okay here's the deal: I need 2 examples of: Mutualism Parasitism Commensalism in a desert. If you can give me some websites that would be good :] P.S. btw I need someone who can explain things very well otherwise a retard, like me, won't get a word you said! ;] so PLZ HELP!!! TY

Question:any basic algae that I can find in a symbiotic relationship with a fungus

Answers:A lichens is such a relationship.

Question:my homework is about giving an example to these relationships but I was struck w/ this question. give an example (photo) to differentiate SMYBiOSIS and MUTUALISM.? i don't quiet get it. can anyone help? and WHAT WAY IS THE RELATIONSHIP BETWEEN A CARABAO AND A CARABAO EGRET BENEFICIAL TO BOTH? AND WHAT IS THE RELATIONSHIP OF THE FF: (PREDATION, COMMENSALISM, MUTUALISM, COMPETITION, PARASITISM) 1. BARNACLE'S ON CRAB'S CARAPACE? 2.MILKFISH AND TILAPIA (KIND OF FISH) BOTH FEEDING ON ALGAE ON A FISHPOND. 3.VENUS FLYTRAP PLANT AND FROG 4.RHIZOBIUM ROOT NODULES ON PEANUTS. THANK UUU VERY MUCH! PLS. HELP! thanks to those who answers but the main thing i was asking was to tell me whether what relationship are the ff: 1. BARNACLE'S ON CRAB'S CARAPACE? 2.MILKFISH AND TILAPIA (KIND OF FISH) BOTH FEEDING ON ALGAE ON A FISHPOND. 3.VENUS FLYTRAP PLANT AND FROG 4.RHIZOBIUM ROOT NODULES ON PEANUTS

Answers:Symbiosis means living together in a close ecological relationship but always inter-specific-it occurs only between different species. Fish can be in two symbiotic relationships by having internal parasites in a parasitic symbiosis and have cleaner fish in a mutual symbiosis. In mutualism both species benefit but in parasitism one species benefits at the expense of the other. In commensalism, one species benefits and the other remains unaffected. Barnacles and whales live in a commensal relationship. Some barnacle species are not such easy partners; the Sacculina is a parasitic barnacle on crabs. http://books.google.com/books?id=X8M7fsyvQo4C&pg=PA205&lpg=PA205&dq=symbiosis+sacculina+barnacle+crab&source=bl&ots=UensCHDFHQ&sig=NY_rPVKgfSWlLDY98Z2Q5dkZq3Y&hl=en&ei=kj15SqjuE4vssQOPhP3fBA&sa=X&oi=book_result&ct=result&resnum=1#v=onepage&q=symbiosis%20sacculina%20barnacle%20crab&f=false In competition, neither species benefits. This is seen when both milk fish and tilapia species feed on the same algae source. Rhizobium are in a symbiosis with legumes like peanuts that is a highly adapted and regulated mutualism. The carabao water buffalo exist with cattle egrets in commensal relationships. The buffalo grazes, disturbing insects for the bird to eat. The bird will perch on the buffalo and also hunt for skin parasites like ticks. http://en.wikipedia.org/wiki/Cattle_Egret A very large venus fly trap can eat a small frog as in the youtube video below, but this is not the typical relationship. http://www.youtube.com/watch?v=B8XQ20X_4s4
