A food chain is a sequence of populations or organisms of an ecosystem through which the food and its contained energy pass with each member becoming the food of a later member of the sequence..

Can any food chain be complete without plants?

No. Explanation: Because the living of the food chain always starts with plants life and ends with animals life. Plants are called producers because they are able to use light energy from the sun, carbon dioxide and water to produce food.

What is a simple food chain?

A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals. A simple food chain could start with grass, which is eaten by rabbits.

What is food chain with example and diagram?

In scientific terms, a food chain is a chronological pathway or an order that shows the flow of energy from one organism to the other. In a community which has producers, consumers, and decomposers, the energy flows in a specific pathway.

What are top level consumers?

The organisms that consume the primary producers are herbivores: the primary consumers. … Tertiary consumers are carnivores that eat other carnivores. Higher-level consumers feed on the next lower tropic levels, and so on, up to the organisms at the top of the food chain: the apex consumers.

What are the five levels of a food chain?

Here are the five trophic levels:Level 1: Plants (producers)Level 2: Animals that eat plants or herbivores (primary consumers)Level 3: Animals that eat herbivores (secondary consumers, carnivores)Level 4: Animals that eat carnivores (tertiary consumers, carnivores)More items…

What is a 5th level consumer called?

The fifth trophic level contains organisms known as Quaternary consumers or Apex predators. These organisms consume organisms in the consumer levels below them and have no predators. They are at the top of the food chain..

What is food chain for Class 4?

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 are the 4 parts of a food chain?

The food chain is made up of four main parts – the sun, producers, consumers, and decomposers. Producers include all green plants. They use energy from the sun to make food. Consumers do not make their own food; they eat other plants or animals.

Why does a food chain consist of only three to four steps?

A food chain’s length is restricted to just 3 or 4 steps due to energy loss. Consequently, the shorter the food chain, the more energy that is available to the final consumer. … A shorter food chain is also considerably more efficient as less energy is lost.

What are the two types of food chain?

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).

What is the first organism in a food chain?

autotrophsProducers, 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 is the difference between a food chain and a food web?

FOOD WEBS show how plants and animals are connected in many ways to help them all survive. FOOD CHAINS follow just one path of energy as animals find food.

What is a 1st order consumer?

1st Order Consumers are animals that eat plants. They are the first step in the food chain. For instance: First-order Consumer – the organism that eats the producer. Second-order Consumer – the organism that eats or derives nutrients from the first-order consumer.

What is the order of the food chain?

The order of a food chain looks like this: sun (or light energy), primary producers, primary consumers, secondary consumers, and tertiary consumers.

What is food chain example?

A food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. eg. Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers — an example is a rabbit that eats grass.

Where do humans sit on the food chain?

The World’s Food Chain Next come the omnivores that eat a mixture of plants and herbivores. That’s where humans rank, with a trophic level of 2.2.

What is the top level of the food chain?

Most food chains have producers, consumers and decomposers. The highest level “consumer” is often referred to as the apex predator. An apex predator is a consumer at the top of the food chain which is not preyed upon by any other predator. That said, most food chains end with what is called a decomposer.
