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?
(a) The sequence of living organisms in a community in which one organism consumes another organism to transfer food energy is called a food chain. An example of a simple food chain is that operating in a grassland: Grass (Producer)⟶Deer (Herbivore)⟶Lion(Carnivore)
What is a 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 explain a food chain to a child?
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. A food chain always starts with plant life and ends with an animal.
What is another word for food chain?
In this page you can discover 3 synonyms, antonyms, idiomatic expressions, and related words for food-chain, like: food cycle, food-web and trophic-level.
What are the 3 food chains?
- Producers – Plants are producers. This is because they produce energy for the ecosystem.
- Consumers – Animals are consumers. This is because they don’t produce energy, they just use it up.
- Decomposers – Decomposers eat decaying matter (like dead plants and animals).
What is a good sentence for food chain?
The food chain affects us all; only a few will be eaten by cannibals. In caves, the basis of the food chain is organic matter from the surface. These measures include the compulsory slaughter of cattle suspected of having BSE and the removal from the food chain of their milk and carcasses.
What is the difference of food chain and food web?
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 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 does a food chain looks like?
A food chain shows you how one organism eats another and transfers its energy. For example, a zebra eats grass, and the zebra is eaten by the lion. The food chain looks like this: Grass – Zebra – Lion.
What is a food chain short answer?
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.
Why is a food chain important?
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 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’s at the 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 of its own.
What does top of the food chain mean?
At or occupying the position of most importance or influence in a social, corporate, or political hierarchy. Some high school seniors revel in the fact that they are now at the top of the food chain, using their newfound and largely imaginary authority to boss around younger students.
What are the 4 parts of a food chain?
All food chains begin with energy from the sun. The food chain is made up of four main parts – the sun, producers, consumers, and decomposers. Producers include all green plants.
What are animals called in a food chain?
Plants and algae (plant-like organisms that live in water) are able to make their own food using energy from the sun. These organisms are called producers because they produce their own food. Some animals eat these producers. These animals are called consumers because they consume something else to get their food.
What is the food chain order?
The order of a food chain looks like this – sun (or light energy), primary producers, primary consumers, secondary consumers, and tertiary consumers.
What are the 5 example 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.
Who created the food chain?
Food chains were first introduced by the Arab scientist and philosopher Al-Jahiz in the 10th century and later popularized in a book published in 1927 by Charles Elton, which also introduced the food web concept.
What are the types of food chains?
There are two types of food chains: the grazing food chain, beginning with autotrophs, and the detrital food chain, beginning with dead organic matter (Smith & Smith 2009).
Where does a food chain starts and end?
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 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 algae and other aquatic plants. These organisms are called producers because they produce energy themselves with help from the Sun.
Where does the food chain start from?
Explanation: A food chain generally starts with producers. Plants or photosynthetic organisms are the main producers. They trap the energy from sunlight and use it to produce food.
Are humans Top of the 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.
