What are the 5 levels of the food chain?
There are five key trophic levels in an ecosystem, from simple plants that get energy from sunlight to apex predators at the top of the food chain.
- Plants and Algae. Plants and algae comprise the lowest level of the trophic system. …
- Primary Consumers. …
- Secondary Consumers. …
- Tertiary Consumers. …
- Apex Predators.

What are the 4 steps of the food chain?
Roughly speaking, these levels are divided into producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers. Producers, also known as autotrophs, make their own food. They make up the first level of every food chain.
What is the process of the food chain?
A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. After that when carnivores eat the herbivores, energy is transferred from one to the other.
What is the correct order of producers to consumers in a food chain?
Hint: The order of any food chain seems like this: sun (or light energy), primary producers, primary consumers, secondary consumer and tertiary consumers.
What are the 7 trophic levels?
Examples of Trophic Level
- Primary Producers. Primary producers, or ”autotrophs”, are organisms that produce biomass from inorganic compounds. …
- Primary Consumers. …
- Secondary Consumers. …
- Tertiary Consumers. …
- Apex Predators.

Who is top of the food chain?
An apex predator, also known as a top predator, is a predator at the top of a food chain, without natural predators.
What is top of the food chain?
“Apex” is a Latin term that means peak or top. Apex predators, also known as alpha predators, are the animals at the top of the food chain and do not have any natural predators in their environment. Apex predators are usually defined in terms of trophic dynamics, meaning they occupy the highest trophic levels.
Why food chain consists of 3 or 4 steps?
Since, the amount of available energy keeps on becoming less as we move to higher trophic levels, so very little usable energy remains after four trophic levels. That is why a food chain consists of only three to four steps.
What is food chain in detail?
A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
What is food chain answer?
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
What comes first in food chain?
The food chain begins with a producer, which is eaten by a primary consumer. The primary consumer may be eaten by a secondary consumer, which in turn may be consumed by a tertiary consumer. The tertiary consumers may sometimes become prey to the top predators known as the quaternary consumers.
What is food chain example?
The definition of a food chain is a system where a small animal is the food for a larger animal which, in turn, is the food for an even larger animal. An example of food chain is a fly being eaten by a frog and then the frog is eaten by a larger animal.
How many levels are in a food chain?
Generally, there are a maximum of four trophic levels. Many consumers feed at more than one trophic level. Humans, for example, are primary consumers when they eat plants such as vegetables. They are secondary consumers when they eat cows.
What are the first order consumers?
Herbivores are animals such as deer which feed on plants. They belong to the second trophic level. Hence they are primary consumers also called first order consumers.
Who is at the bottom of the food chain?
Plants and algae, which use energy from the sun to produce all their food, sit at the bottom of the food chain, with a trophic level of 1. Right above them are herbivores, such as rabbits, cows and deer, which have a trophic level of 2.
What is at the end of the food chain?
A food chain is a linear network of links in a food web starting from producer organisms (such as grass or trees which use radiation from the Sun to make their food via photosynthesis) and ending at an apex predator species (like grizzly bears or killer whales), detritivores (like earthworms or woodlice), or decomposer …
What is a food chain prey?
Any animal that hunts and feeds on other animals is called a predator, and the animals that predators feed on are called prey. All carnivores are predators, and herbivores—and sometimes omnivores or other carnivores—are their prey.
What is food chain and diagram?
A food chain is a linear diagram showing how energy moves through an ecosystem. It shows only one pathway out of the many possibilities in a specific ecosystem. BiologyFood Chain.
Why do most food chains have 3 to 5 steps only?
At each trophic level a lot of energy is lost in the form of heat or is used for the maintenance because of which only 10% energy is transferred to the next trophic level. As such little amount of energy is transferred the trophic levels/ steps are limited to 3-5 only.
Why are most food chains only 3 5 steps?
A food chain's length is restricted to just 3 or 4 steps due to energy loss. Moreover, the energy added to the biomass of each trophic level is significantly lower than the one preceding it. This occurs as a result of material wastage from subsequently trophic levels and for the maintenance of various life processes.
How do you explain a food chain to a child?
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.
What is food chain types?
There are two types of food chains, namely the detritus food chain and the grazing food chain.
What is the start of the food chain?
plants All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of 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.
What does a food chain end with?
Thus the living part of 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.
What are the 4 trophic levels?
Trophic Levels
| Trophic Level | Where It Gets Food |
|---|---|
| 1st Trophic Level: Producer | Makes its own food |
| 2nd Trophic Level: Primary Consumer | Consumes producers |
| 3rd Trophic Level: Secondary Consumer | Consumes primary consumers |
| 4th Trophic Level: Tertiary Consumer | Consumes secondary consumers |

What is a food chain Grade 6?
A food chain explains which organism eats another organism in the environment. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. This occurs when one organism consumes another organism.
What are 2nd order consumers?
Some flesh eating or carnivorous animals eat flesh of the first order consumers or herbivorous creatures, for example, rabbit, goat, deer, sheep etc. So they are called the second order consumers. A frog eats insects, so it is second order consumer. Some carnivores eat other carnivore animals.
What are 3rd order consumers?
Third-level consumers are any organisms big enough to obtain energy by feeding off lower-level consumers. These are also called tertiary consumers. For example, in a forest ecosystem, snakes eat toads. Heron and large fish, such as bass and walleye, consume smaller fish, frogs and crayfish.
Are humans top of food chain?
At the top of the scale are meat-eaters that don't have any predators themselves, such as polar bears and orca whales. Instead, we sit somewhere between pigs and anchovies, scientists reported recently. That puts us right in the middle of the chain, with polar bears and orca whales occupying the highest position.
What is the first thing in a food chain?
The first organism or first link in the food chain is a producer. Producers are plants; they can be grasses, fruits, trees, vegetables, or ocean…
