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 food chain in science terms?
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 is food chain and example?
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. A rabbit eats the grass. A fox eats the rabbit.
What is a food chain in Science for Kids?
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 in short answer? – Related Questions
What is a food chain for grade 4?
A series or sequence of links showing how nutrients and energy pass from one organism to another is called food chain. All food chains start from producers i.e. plants. Plants are called producers as they make food with the help of sunlight, water, carbon dioxide and nutrients from the soil.
What is class 3 food chain?
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.
What is a food chain Class 1?
All living things need energy to live and grow, and the flow of energy from one organism to another is called a food chain. Starting the food chain are producers, which are plants, fruits, and vegetables that make their own energy from the sun. Consumers eat producers and get their energy from them.
What is a food chain 5th grade?
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.
What is food web in simple words?
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.
How do you introduce a food chain to students?
17 Cool Ways to Teach Food Webs and Food Chains, In Person and Online

- Use a paper plate to show the circle of life.
- Try some StudyJams.
- Create food chain art.
- Construct food chain pyramids.
- Have a digital Food Fight.
- Assemble food chain links.
What is the importance of food chain?
Food chains are important because they show the intricate relationships in ecosystems. They can reveal how each organism depends on someone else for survival. Food chains also display what happens when a problem occurs and a producer or consumer is lost. Entire communities can collapse.
What is common to all food chains?
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 is food chain 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. Food Chain — Definition & Examples.
What is a food chain Grade 6?
The sequence of living creatures that represent who eats whom in an ecosystem is called a food chain. The food chain describes how an organism derives energy and nutrients by eating other organisms. It shows the relationship between the producers and the consumers (e.g. deer, goats, cows and tiger).
What is a food chain Class 7?
A food chain is a linear sequence of organisms in which each organism is eaten by the next member in the sequence. This interaction among organisms involves the transfer of energy from one organism to another.
What is a food web Class 10?
A food web is a network of food chains which are interconnected to each other. In a food chain, each member is eaten by the other in a particular sequence. The producers, consumers and the decomposers of the various food chains are considered as the part of the food web.
How does energy flow in an ecosystem?
The energy flow takes place via the food chain and food web. During the process of energy flow in the ecosystem, plants being the producers absorb sunlight with the help of the chloroplasts and a part of it is transformed into chemical energy in the process of photosynthesis.
What are trophic levels write the name of all four trophic levels in the given figure?
There are 4 trophic levels it includes producers, herbivores (primary consumers), carnivores (secondary consumers), predators (tertiary consumers).
What is the 10% law?
According to the law, during the transfer of organic food from one trophic level to the next, only about ten percent of the organic matter is stored as flesh. The remaining is lost during transfer or broken down in respiration.
How do you calculate ecological efficiency?
Ecological efficiency is defined as the energy supply available to trophic level N + 1, divided by the energy consumed by trophic level N.
What is percent law explain with an example?
Ten PerCent Law – According to ten per cent law only 10 per cent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level. Example – Suppose 1000 Joules of light energy emitted by the sun falls on the plants.
