What is food chain in easy English?
A food chain shows the feeding relationship between different organisms in a particular environment and/or habitat. Plants are at the bottom of a food chain because they are producers that make their food from a process called photosynthesis . Organisms that can make their own food are called producers.
What is food chain short 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 do you mean by 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. ... In the food chain, energy is transferred from one living organism through another in the form of food.
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 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 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.
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.
Why is food chain important?
Food chains are important because they show the intricate relationships in ecosystems . It is seen that in food chains, each organism fills a specific niche in an ecosystem. Food chains reveal how each organism depends on someone else for survival.
What are some examples of 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 a food chain for kids?
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 in an ecosystem?
The food chain describes who eats whom in the wild . Every living thing—from one-celled algae to giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem. For example, grass produces its own food from sunlight.
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 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. Trophic levels include different categories of organisms such as producers, consumers, and decomposers.
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.
