No. The predator has to eat something.
The jaguar is the top predator of the food chain, it has no natural predators - only man.
A field mouse is never at the bottom of a food chain because only decomposers (like worms and bugs) or plants (grass usually). A mouse is never at the top because it is not a predator. A simple food chain to help me explain would have grass or grains at the bottom and the mouse in the middle because it eats the grains/grass then the owl would be at the top because it's a predator and eats mice. You always end a food chain with a predator.
They are the top predator although humans will poach the tigers but they are still the top predators. Due to this they only get 0.1% of the energy that came from the feeder at the bottom of the food chain.
A carnivore at the highest level of the food chain. It eats only other carnivores and is usually the top predator in an ecosystem
it depends, doo you a food chain with only one preditor, or two or more? if one then the food chain is out of wack if two or more then the one that went extinced well then the other preditors will haves more food
A food web is more accurate than a food chain. Animals eat different things, and are eaten by different things, a web will show all or most of its predators and prey, whereas a food chain will only show one predator and one prey.
The white shark is an apex predator (on top of the food chain) and as such, has very few predators. Killer whales and larger sharks pose the only natural threat to an adult white shark.
The food chain is actually a loop. Bunny eats carrot, cheetah eats bunny, maggots eat cheetah (after death), soil absorbs maggots, carrots absorbs soil, bunny eats carrot ... it goes round and round.The closest thing you could say is that cheetahs are at the top of the predatory food chain.
Wolves in the wild are at the top of the food chain. The only predictors to wolves are perhaps other wolves. For example when food is low it's not uncommon for the alpha to eat the weak or injured. Though it's not a predator of the wolf bears have been know to kill a wolf.
Lions are predators that hunt for food the are on the top of the food chain and their only threat are humans or other lions. They mostly hunt but on rare occasions they would scavenge
Apart from human intrusion into their environment, their only natural predator is the dingo, but introduced species like dogs, cats and foxes can also hunt them for food. Aborigines also hunted wombats for food.
A food chain can only be up to 5 trophic levels in length, including the producer. Only a small proportion of the previous organism's energy is passed down through trophic levels to the next organism. This diminishes the energy available, so there is little or no energy to be gained after the 5th stage of a food chain. :)
