Why should you avoid fish at the top of the food chain?

Fish at the top of the food chain contain too many toxins.

Because there are too many toxins in the body.

Fish at the top of the food chain are the most likely to contain the most waste.

Because fish at the top of the food chain are the least safe.

Too many toxins accumulate at the very top of the food chain.

Because the more the top, the more poisonous.

The more you are at the very top of the food chain, the more harmful substances in your body.

The fish at the top contain more toxins.

Tigers, lions, eagles, eagles, sharks, whales, without human intervention, they will certainly be in smaller numbers compared to herbivores. The number of animals at the top of the food chain depends on the natural environment (the number of food source habitats), and if there are more food source habitats, their numbers will also increase. If there is less food and water habitat, their numbers will also decrease.

The factors of the natural environment and the contradictions within the population keep their numbers stable, like a pack of rabbits. Living on a prairie. If there are no other animals that threaten them, then they will look at breeding.

And after reproduction to a certain extent. There will not be enough grass to eat, and the number of rabbits will plummet. And the grass grows again.

The number of rabbits continues to increase, and so on and so forth.

You don't know that these animals are almost gone now, and as long as there are human restrictions, the number will not increase.

Energy transfer is characterized by a step-by-step decrease.

Because only part of the energy of organisms located at the lower levels of the food chain can be transferred to the upper levels, the rest will decay and dissipate in nature. Therefore, the total energy obtained by animals at the top of the food chain is relatively small, and the quantity is naturally smaller.

Decreasing levels – The amount of energy fixed by the various parts of the ecosystem is decreasing gradually. In general, the further you move to the back of the food chain, the fewer the number of organisms, creating a pyramid-shaped trophic hierarchy.

There are two main food chains in any ecosystem, the grazing food chain, which starts with living animals and plants, and the detrital food chain, which starts with dead organisms or detritus.

In most terrestrial and shallow water ecosystems, the majority of biomass is not fed, but is broken down by microorganisms after death, so energy flow is dominated by the detrital food chain.

The main path of energy flow in the ecosystem is that the energy enters the ecosystem in the form of solar energy, and the energy stored in the form of plant matter flows through the ecosystem along the food chain and food web, and is stored in the system in the form of chemical potential in animal and plant matter, or is exported as a product, leaves the ecosystem, or is lost from the system by the respiration of consumers and decomposer biological organisms. Ecosystems are open systems, and certain substances can also be imported through the boundaries of the system, such as animal migration, water flow, and human replenishment.

The flow of ecosystem energy is unidirectional. After energy enters the ecosystem in the state of light energy, it can no longer exist in the form of light, but constantly escapes in the form of heat in the environment.

The food chain is generally pyramid-shaped because of the flow of energy.

The first stage producer fixes the solar energy, after which a part of it flows to the next trophic level, which is 10 -20. It can be seen that the higher the trophic level, or the less energy, so the smaller the quantity. Think about it, if the number of tigers and rabbits is about the same, then the rabbits will be eaten quickly, and there will not be so many tigers at all.

Of course, there is also a case that is not pyramidal, tree with aphids.

I think this is also a big reason for the fact that the animals at the top of the food chain are not very reproductive, and if there is no human influence, there are generally fewer offspring, and the offspring of some animals are easy to be preyed on, and I think this is also a big reason, not just energy.

Man is the highest animal, and man can change the food chain.

If Bei Ye said that he was not a creature standing at the top of the food chain, then humans would not be on the list.

Go check out "Survival in the Wild", and after watching it, you will know that not everyone can stand at the top of the food chain.

Humans live at the top of the food chain with their intelligence, and they can't face crocodiles with their bare hands.

Because man is a superior animal, man has wisdom and brain, man can invent all kinds of **, and is the master of this world.

At the top is the orca, which can kill the great white shark, and there are a lot of related videos!

Large carnivorous sharks, such as great white sharks.

People are caught by marine life.

It's the great white shark, the man and nature that I just watched today.

Killer whales, sperm whales, great white sharks.

With the increase of trophic level, because the transfer of energy from the upper level to the next level is only 10 to 20 percent, so the number of higher animals will be less - except for humans, and animals will rely on their own intraspecific competition and racial competition to regulate the number, for example, a large increase in rabbits, will reduce rabbits through the predation of rabbits and other animals such as rabbits, if there are no natural enemies such as wolves, but rabbits reproduce to a certain stage, when they reach the maximum value of environmental capacity, various resources are limited, and they will be regulated by their own intraspecific competition. The behavior is equivalent to the collective suicide of some animals or fighting each other.

Animals at the top of the food chain are regulated by intraspecific competition between the organisms below them and their own species. The food chain is a kind of predation and feeding relationship between organisms, and each link affects each other. For example, when the number of wolves is large, the number of creatures he preys on decreases, and the number of wolves decreases due to the decrease in the amount of food.

After that, the number of creatures he preys on will increase due to the lack of natural predators. Leads to an increase in the number of wolves.

Because the loss of energy transfer in the food chain is very large, the energy that can be obtained at the high end is very small, and they are generally large carnivores, and the few energy individuals are huge, so the number will naturally be very small.

Win a cup in the land of Africa, three checks in eternity, one hundred.

Apex predators, or superpredators, are at the top of the food chain.

An apex predator is a predator that is generally not hunted by other species within a valid part of their range. Usually at the very top of the food chain, such as lions, tigers, jackals, wolves, bears, Nile crocodiles, killer whales, sperm whales, etc. It is located at the top of the food chain and has no natural predators.

And some are also potential cannibals, though they may act little for fear of human retaliation.

If you ask this question, it shows that your understanding of the concept of food chain and food web is not complete, and it makes no sense to talk about the food chain without a specific ecological environment, but it makes sense to talk about animals at the top of the food chain in a specific ecological environment. In general, it can be considered that animals such as lions, tigers, and eagles are at the top of the food chain, but there is no "most", because in a different ecological environment, people may not eat tigers. It's a bit messy.,The landlord understands it himself.。

Regardless of the natural environment, such as in the Arctic, polar bears should be the animals at the top of the food chain. Sharks, killer whales, sperm whales in the ocean should be the animals at the top of the food chain. But the animal at the top of the global food chain on land is the anacond, and a common analea can eat a caiman like a mouse.

Except for mutated and super-large animals. An ordinary python fights a great white shark, I guess it's a python, and an adult python has great strength. That's why I recommend that the worm is the animal at the top of the terrestrial food chain.

In the ocean, killer whales are at the top of the food chain, and killer whales can even eat great white sharks.

The strongest king at the top of the food chain, the animal with the strongest bite in the world.

No, humans can kill pythons, and pythons can swallow people. If human beings do not use tools, they will no longer be at the top of the food chain, but at the bottom.

Actually, there is no top of the food chain, but there is actually a top, and the marine food chain does not, but from the land, actually, the top of the food chain is humans.

Since the discovery of fire, there has always been only one at the top of the food chain, and that is humans! Without any natural predators, lions and tigers are strong? Even species need human permission to exist for survival, and if they are not allowed, they will become extinct in the world in half a day.

At this time, there will be a bar spirit to say, if human beings don't take the **, I can only tell you, don't be too naïve, there are not so many ifs in this world. In addition, tigers and lions are incomparable, a guy who can only fight alone will not have much success, and humans are good at holding together, so humans have become the masters of the world.

There is no one, only some organisms can reach the top of the food chain, and humans do not belong to this genus! There is no doubt that the top creatures on land, lions, tigers, hyenas (individual strength is not good, but group strength makes hyenas rampant in the African savannah), brown bears, polar bears, Komodo dragons, these are all recognized as the top creatures of the food chain, and of course there are other creatures that I will not list!

In the ocean, killer whales and sperm whales, as well as great white sharks, bull sharks, can be rampant.

The top of the food chain does not mean that there are no natural predators, only that there are almost no natural predators.

In fact, people are the masters of everything, although they are only a kind of advanced mammals.

Depending on the specific food chain, what is at the top of one food chain may be at the bottom of the other chains, and a species does not exist in only one food chain, because the food chain is intricate! There are natural enemies, so that they can restrain each other and balance the ecology.

Because humans have the ability to move in all terrain that is unimaginable to other animals.

The creatures at the top of the food chain are all state-protected animals, and people can't eat them at all. Strictly speaking, humans are really not at the top of the food chain.
