A food chain is a pathway that represents the exchange of energy from one organism to another. 1) what is food chain explain with various example 2) what is food chain and write down its characteristics 3) what is food web make diagram of one example of food web.
In other words, it is the chronological order of who eats whom in a biological community.
What is food chain give an example. During the 1920s and 1930s, the pioneer british ecologist charles elton studied the ecology of arctic lands. Here are some examples of food chains: The butterflies feed on nectar and, at the same time, are the food of other insects that are the food of bats.
They use photosynthesis to make their own food. The grass, deer and tiger form a food chain (figure 8.2). B) long answer type question.
A food chain is mostly made up of three trophic levels. Most of the ecosystems in nature exhibit this type of food chain. The producers form the first trophic level as they manufacture food.
The various links or steps in a food chain at which the transfer of food and energy takes place are called trophic levels. Examples of food chains in this category include: (ii) parasitic food chain, where organisms tend to decrease in size as one goes higher up the food chain.
It may also be defined as follows. First, let's talk about the example of the food chain in the wetland ecosystem. In a forest ecosystem, grass is eaten by a deer, which in turn is eaten by a tiger.
It starts with the primary source , like the sun or hydrothermal vents, where producers make food, continues with consumers , or animals who eat the food, and ends with the top predator. Consumers are all organisms that are dependent on plants or other organisms for food. → primary consumers are animals that belong to second trophic level and feed on plants.
Food chains in rice fields. The green plants are the food of all herbivores that are primary consumers. Example of a predator food chain:
A food chain is a link of simple organisms which include only a few animals or plants while as a food web is a complex food system which can include many varieties of organisms. A food chain in an ecosystem is a series of organisms in which each organism feeds on the one below it in the series. This type of chain thus depends on autotrophic energy capture and the transfer of this captured energy to herbivores.
What is food chain ? Here is an example of a food chain from various ecosystems complete with pictures that we will discuss one by one. An example is shown in the diagram.
In a food chain, each step representing an organism forms a trophic level. In the above food chain. 11) give two example of food chain.
The sequence of eating and being eaten with the resultant transfer of energy from one level to another level is known as food chain. Grasshoppers are the primary consumers, and represent the second trophic level. An example of food chain is a fly being eaten by a frog and then the frog is eaten by a larger animal.
Give example asked by nathsantanukumar 27th april 2018 9:47 pm. The primary consumers form the second trophic level, the secondary consumers form the third, and the tertiary consumers form the fourth trophic level. A food chain is when a producer is eaten by a consumer, and then that consumer becomes prey for a predator, which then becomes prey for another consumer, and so on.
Primary consumers are the second link of a food chain. (0) 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. 1) flow of energy in food chain is.
H owever, some trophic levels have four trophic levels. Answered by expert icse viii biology ecosystems explain the different trophic levels of a food chain asked by nathsantanukumar 27th april 2018 9:58 pm. Well, for starters, a food chain is a series of interconnected feeding relationships among different species in an ecosystem.
An example of 4 steps food chain is: Energy is not created or destroyed. The hens feed on corn and their eggs are the food of the weasels that, at the same time, are hunted by snakes.
Food chainfood chain tells us how energy is transferred from one organism to another.it is a linear sequence of organisms (i.e. Please do mark me as brainliest⭐⭐⭐. Let’s look at some types of food chain in the examples below.
They are usually herbivores that eat green plants or sometime omnivores that eat both plants and animals. In a community which has producers, consumers, and decomposers, the energy flows in a specific pathway. 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.
One example of a food chain is grass,then grasshopper, then frog, then fish, then snake, then bigger fish, then alligator, then human, then calusa. → primary producers which are plants that are autotrophs and belong to the first trophic level. One example of producers found in food chains include plants.
This study can be cited as an example of a predator food chain (fig. Thus, plants are the producers, and represents the first trophic level. When they die, they are broken down by organs and worms.
Rice fields are an artificial ecosystem consisting of almost homogeneous organisms at all trophic levels. Grasshopper eats grass, frog eats the grasshopper and snake eats the frog. For example, green plants, fruits, phytoplanktons, small plants, and algae are some examples of producers in a food chain.
Examples of plants include trees, grass, moss, flowers, and weeds, to name a few. The term food chain refers to the sequence of events in an ecosystem, where one organism eats another and then is eaten by another organism.
