The food web is directed but not acyclic, meaning that arrows can point in a loop.
An example of a directed, acyclic “web” (technically a graph), would he books being published that quote other, previously published books.
Another is (ideally) the library dependencies of a codebase. If you end up with a loop in your dependency graph your package manager will probably fail.
An example of a non-directed graph is the covid contact data that our phones were collecting if we opted in during the pandemic. If I was close to you, you were close to me. It basically means if we drew you and I as dots on paper, it would be a line connecting us not an arrow.
The food web is directed (there is the eater and the eaten) but not acyclic. I can eat a bear, and the bear can eat me, which would be represented not as one line, but as two arrows pointing to and fro.
Great explanation of the concept of a food web. Grew up only knowing the food chain as well. Still kind of fuzzy on the rules for direction with certain animal pairs and whether it’s based on predation capability or something else.
Yep saw that one and another with a deer eating a bird. So I think there’s new categories for animals now too on what they eat. Instead of carnivores, omnivores, and herbivores. There’s obligate carnivores and opportunistic carnivores. Apparently even pandas would kill for some protein if given the opportunity.
Gonna be a 3-D food web once we get all the new science rules settled.

Rule 1- All posts must be legitimate questions. All posts titles must include a question.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That’s it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it’s in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content. Rule 9- Reposts from other platforms are not allowed.

After I saw the video of the horse eating the chick I just gave up on trying to understand it

Has there been two papers that quote each other?
