I at first found the notion a bit ridiculous, but then I found this Venn diagram on Wikipedia's article on predation:  |

Some maybe, but even those predators who eat grass usually leave the roots intact and those who eat leaves leave the tree intact. Only few of them actually kill the plant (if a plant regrows, it's not dead), but killing the organism is a vital component of predation.

No, predation requires killing the organism. Grass regrows.

No, predation requires killing the organism. Grass regrows. how about fruit? when say a horse eats a apple |

Well, that would technically be browsing (since only a part of a plant is eaten), and according to the Venn diagram, that doesn't fall under predation.
I'm a little confused by the diagram, though. It defines parasitism as when prey stays alive. Browsing and even many cases of grazing (where the herbivore doesn't eat the root, leaving it to regrow and continue living) involves the prey staying alive, so...yet they don't overlap. Intuitively I can't imagine why they would, though.

That's a good point, I think it would be better to define parasitism as the exploitation of another organism's metabolism or as a form of antibiosis where the parasite requires special adaptations that make living without the host nearly impossible (admittedly, each of these definitions has its edge cases). rockAs Infinity Blade said, fruits are not organisms. |

Yeah.....I am not sure at all. Those diagrams are just throwing loops and loops

It's not. A fruit is more like an egg. Technically, only the seed is the egg. Most animals only eat the stuff around the seed and the plant counts on the animal doing precisely that. The seed usually doesn't get swallowed or survives digestion so that it enters the ground bare and allows a new plant to grow. Nothing is killed here, think of it as peeling the shell off of an egg.

Except that frugivores only peel off the shell whilst doing nothing to the embryo. Nothing is killed here, all that is done is the consumption of biomatter.
