A food chain shows a sequence of living things in which one organism eats the one below it . Most animals eat more than one thing, so to show ALL the feeding relationships, we use food webs which are made of many intersecting food chains.
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 a food chain simple definition for kids?
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 web and chain?
A food chain outlines who eats whom . A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid.
What is food chain and food web in short answer?
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. ... Food chain and food web form an integral part of this ecosystem.
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 types?
There are two types of food chains, namely detritus food chain and grazing food chain . ... The detritus food chain begins with dead organic material. The food energy passes into decomposers and detritivores, which are further eaten by smaller organisms like carnivores.
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.
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 is food chain explain with diagram?

What is food web examples?
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.

What is a food web explain with example?
A network of interconnecting food chains in a natural community of different organisms is called a food web. Example of Food Web. Consider six food chains which are interconnected to form a food web. The food web begins with plants and ends with the top carnivore, the vulture.
What is a food web easy definition?
A food web consists of all the food chains in a single ecosystem . Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.
What is difference between food web and food chain 10?
Food chain is defined as the process of energy transfer from producer by a series of organisms with repeated eating or being eaten. Food web is defined as the interconnected network of food chains at various trophic levels. ... It provides an alternative path of food stability .
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 differences between food chain and food web?
A food chain is a basic network that shows the linear flow of nutrients and energy from one trophic level to another. A food web is a multitude of food chains that are interconnected at many trophic levels. Furthermore, a food web accurately represents all the various food chains that exist in an ecosystem.
