A food chain is a series of organisms where all the organisms are dependent on next organism as a source of food. All the components of forests are interrelated to one another. Autotrophs, heterotrophs and saprotrophs in the forest are connected to each other.
What is a food chain kid definition?
The term food. chain describes the order in which organisms, or living things, depend on each other for food . Every ecosystem, or community of living things, has one or more food chains. Most food chains start with organisms that make their own food, such as plants. Scientists call them producers.
What is a food chain easy definition?
Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism . ... Plants, which convert solar energy to food by photosynthesis, are the primary food source. In a predator chain, a plant-eating animal is eaten by a flesh-eating animal.
What is food chain for class?
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. It begins with producer organism, follows the chain and ends with decomposer organism.
What is food chain and 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. noun.
What is food chain with 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.
What are the 4 food chains?
On the blackboard, write the following headings: Producers, Primary Consumers, Secondary Consumers, and Tertiary Consumers . Ask students to name some species under each heading. Then demonstrate how to create a food chain, using some of the species listed.
What are plants called in a food chain?
Plants form the base of Great Lakes food chains. They're called producers , because they make their own food by converting sunlight through photosynthesis. They also act as food, providing energy for other organisms.
What are examples of a food chain?
- Nectar (flowers) – butterflies – small birds – foxes.
- Dandelions – snail – frog – bird – fox.
- Dead plants – centipede – robin – raccoon.
- Decayed plants – worms – birds – eagles.
- Fruits – tapir – jaguar.
- Fruits – monkeys – monkey-eating eagle.
- Grass – antelope – tiger – vulture.
- Grass – cow – man – maggot.
What is an example of a food web?
eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected . eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal. The snake may eat a beetle, a caterpillar, or some other animal.
Which is the correct food chain?
The process of transfer of energy from producers through a series of organisms, i.e., from primary consumers to secondary consumers and from secondary consumers to tertiary consumers by process of eating and being eaten constitute a food chain. The correct food chain is phytoplankton >> zooplankton >> fish.
Is food chain is always straight?
| Food Chain Food web | Food chain is always straight and proceeds in straight manner Unlike food chains, food webs are never straight. |

What is difference between food chain and food web?
A food chain follows one path of energy and materials between species . A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. ... Producers are the basic trophic level while top predators are the peak level.
What is food chain and food web explain with diagram?
Food chain is a linear sequence of organisms which starts from producer organisms and ends with decomposer species. Food web is a connection of multiple food chains . Food chain follows a single path whereas food web follows multiple paths. From the food chain, we get to know how organisms are connected with each other.
What is a food chain Class 10?
A food chain is a series of organisms where all the organismsare dependent on next organism as a source of food . The series of organism take part at various biotic levels to form a food chain. Each step of the food chain forms a tropic level.
What comes first in a food chain?
Producers , also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.
