Many of Earth’s creatures see humans as super predators. And no, that title is not as great as it sounds.
What is the order of a food chain?
The order of a food chain looks like this: sun (or light energy), primary producers, primary consumers, secondary consumers, and tertiary consumers.
Are humans on the top of the food chain?
Humans aren’t at the top of the food chain. In fact, we’re nowhere near the top. Ecologists rank species by their diets using a metric called the trophic level. … They found that the global HTL average is a measly 2.21, which puts the human diet on par with pigs and anchovies.
What is at the top of the food chain?
Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow. At the top of the system are the apex predators: animals who have no predators other than humans. Help your class explore food chains and webs with these resources.
What is the greatest predator of all time?
SpinosaurusSpinosaurus discovered – the largest predator ever to walk the Earth – Telegraph.
Who eats the lion?
Lions have almost no predators. However, old, sick lions are sometimes attacked, killed and eaten by hyenas. And very young lions can be killed by hyenas, leopards and other predators when they are not being watched carefully by their mothers. But a healthy adult lion has little to fear from any other animal.
What are the 5 levels of the food chain?

Plants and algae comprise the lowest level of the trophic system. … Primary Consumers. … Secondary Consumers. … Tertiary Consumers. … Apex Predators.
Do humans have a natural predator?
Originally Answered: Do humans have natural predators? No, but sometimes cases of man-eaters have involved lions, tigers, leopards, and crocodilians. … There were also many large animals in the past that preyed on humans, but humans killed most of them, so that’s why you don’t know about them.
What is a food chain and give examples?
A food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. eg. Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers — an example is a rabbit that eats grass.
Are humans the ultimate predator?
Predators that exert a top-down control on organisms in their community are often considered keystone species. Humans are not considered apex predators because their diets are typically diverse, although human trophic levels increase with consumption of meat.
What predators do humans eat?
Most reported cases of man-eaters have involved lions, tigers, leopards, and crocodilians. However, they are not the only predators that will attack humans if given the chance; a wide variety of species have also been known to adopt humans as usual prey, including bears, Komodo dragons and hyenas.
What does a food chain show?

What is the 5th consumer called in a food chain?
Quaternary consumersThe fifth trophic level contains organisms known as Quaternary consumers or Apex predators. These organisms consume organisms in the consumer levels below them and have no predators. They are at the top of the food chain..
What is food chain for Class 4?
A food chain is the transfer of food energy from plants to an animal and then to another animal. Most food chains start with green plants making food energy from the sun. Then an animal eats the plant and another animal eats that animal. Green plants in a food chain are called producers.
Where do humans lie on the food chain?
