Even though we are omnivores, we are apex predators. Nonetheless in primitive/ wilderness areas we sometimes fall prey to other apex predators such as crocodiles, tigers etc.
We are also often "lunch" for parasites and eventually (like all things that die) decomposers.

Not to set out to confuse but I feel the food chain is an outdated idea about evolutionary relationships from the 19th century. People have pointed out that we are often 'eaten' by bacteria but you cant really say they're a predator on the next rung up - they'll consume any decomposing animal.

Generally we are at the top of the 'food chain' since with our technology, rifles and fire we tend not to let other animals eat us. It might be true that sometimes an animal will attack and kill a human but we cant be considered a major part of their diets. One exception to this might be parts of India where they still have big problems from time to time with man-eating leopards. They even enjoy killing for sport like humans - a panther in Tanzania killed 27 humans and didnt eat any of them.

A food chain will usually start with a plant - even a single celled alga and then be host to a sequence of larger predators. However this doesnt adequately reflect the complex relationships there are in nature. Look up 'co-evolution' for an insight.

No humans have reached the top of the food chain. We were part of it a long time ago but as we turned from hunter gathers into farmers we removed our self from the food chain and put oursleves at the top. Apart from the odd animal attacking we are at the top of the food chain. We have no predatation of the human species. There is no predator keeping our numbers down. All animals that have had long term contact with humans in the wild learn to fear us.

A food chain is:

A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees & shrubs, the giraffes (that eat trees & shrubs), and the lions (that eat the giraffes). Each link in this chain is food for the next link. A food chain always starts with plant life and ends with an animal.

Plants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water.

Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers. There are three groups of consumers.

Animals that eat ONLY PLANTS are called herbivores.

Animals that eat OTHER ANIMALS are called carnivores.

Animals and people who eat BOTH animals and plants are called omnivores.

Then there are decomposers (bacteria and fungi) which feed on decaying matter.

These decomposers speed up the decaying process that releases mineral salts back into the food chain for absorption by plants as nutrients.

A simple food chain would be something like this.

A field of grass grows using the sun and nutrients in the soil.
A cow eats the grass.
We eat the cow

If you want a genuine food chain. Its more of a food web as there are many species that may prey on a single species. A tree may support many different species of insect feeding on it. But not all of them will be eaten by tha same birds or small mamal. But futher up the food chain a bird of prey may eat both the bird and small mamal. And There is also the return of nutrients back into the system. The effects on one link in the chain will be felt through the rest of the chain.

Look at the link so understand more.

Yes, humans are part of the food chain -- the top -- for many animals (cows, sheep, pigs, salmon, etc.) A food chain always starts with a plant, since plants can make their own food. Animals cannot make their own food, so tsome of them eat the plants to get nourishment. Some animals cannot eat plants, so they must eat other animals. A genuine food chain starts with the plants, progresses to the first animal that eats the plant, and then proceeds through successively larger animals that eat the smaller animals which ate the plants. Some food chains may have just two members (cabbage -- human) while others may have several (plankton -- snail -- small fish -- large fish -- human)

i imagine this all boils all the way down to our perspective on lack of existence and suffering. there's a organic stability to nature, and gazing it as benevolent or malevolent is purely lacking the point. In my nature i believe a repugnance in the route of killing something to eat. which could no longer how my cat feels at the same time as eating a mouse. people have killed off maximum of our predators, and which could no longer an excellent element. purely imagine that once you go outdoors to get on your vehicle to bypass to artwork, how a lot extra alert on your ecosystem you'd be in case you've been searching for a cougar. you'd be unsleeping. We go by this existence on snooze. you are able to sparkling up your area of causing soreness in case you so choose, by no longer eating animals. Watch a cat eat a mouse and spot that there isn't any moral judgment on the area of the cat or the mouse, it truly is what it truly is.

The best solution is to gain control over it. As someone already said, stop when you're getting there and relax. Pay more attention to pleasuring your mate--orally, perhaps--and avoid rubbing your penis up against anything while doing so. It will take work on your part and patience on both parts. Learn here http://EndPrematureEjaculation.enle.info/?GaoO

As a last resort, some antidepressants curb sexual functioning with the intention of learning the pleasure of restraint after which you could taper off them. Here's your goal: the longer you can delay your orgasm, the more intense it will be. So it isn't just a matter of satisfying your mate. This is the main reason some claim stoned sex is better, unlike drunk sex which can leave you unable to perform (brewer's droop). You enjoy exploring each other longer. And remember, oral isn't just one place. It's all over, paying particular attention to kissing, and TALK about what each of you like. Strange how people don't talk about sex when they're the ones doing it.

yes we are a "part" of a food chain

we are currently the top, and so don't get predated (most of the time!)
however i feel the term "food chain" is confusing...

it suggests that each organism only eats 1 type of food...

humans are omnivores we eat plants and animals

other animals do eat other things ie birds don't just eat worms! beetles, butterflies, other birds, frogs, fish... etc etc etc

"food web" is much more accurate

any organism that eats any other (including plants or parasites)
is part of the food web/chain

hope that helps!

Reasonably briefly: It is widely accepted that only polar bears will actively try to source humans as a meal, other animals may by particular circumstances become 'man eaters' either because the eg. tigers infirmity to hunt deer leads it to take humans as a soft target, or e.g crocodiles because we 'give ourselves up' by entering their rivers. Probably the greatest man eating sensation is the one attached to sharks, esp the great white but again research seems to suggest that man has been mistaken for seals or more natural prey. After all a shark could not survive as a species if it had to rely on humans, there just aren't enough of us in the water ! Also sharks tend to bite to disable and then wait, human swimmers not unnaturally tend to get or be or be pulled out of the water. The basic food chain theory is a pyramid with plankton, shrimps and small creatures and vegetation at the bottom, being consumed by more developed creatures, faster and or more intelligent creatures, right up to man himself at the top. The precise pattern can be varied by the introduction of environment variables ie. a land or water based, or mixed land and water based structures.

a food chain is a collection of animals and plant which consumes, as well as, gets consumed.

man is also a part of it as he is an omnivore (plant and animal eating).

cud be anythn..like man eats chicken, chickens eat seeds, seeds got from plants..

ultimately all r decomposed by microbes in soil.
so the chain is complete!

I would think before man was as advanced as we are now, Lions and Other carnivores, IE tigers, wolves, and such hunted us . until we evolved into the species we are now...I would think a food chain would have to start with , the smallest part consuming a form of one celled bacteria and progress up to the largest carnivore .. so in a sense there is only one food chain we are just a small part of it.
