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 do you mean by food chain explain with an example?
The sequential process of eating and being eaten is called a food chain. Grass → Grasshopper → Snake → Hawk → Fungi. All food chains begin with green plants or producers. Thus, the plants or producers constitute the first trophic level. Example: Grass.
What is the food chain explain?
A food chain explains which organism eats another organism in the environment . The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. ... It begins with producer organism, follows the chain and ends with decomposer organism.
What is 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.

Producers , 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 are plants called in a food chain?
Plants form the base of Great Lakes food chains. They're called producers , because they make their own food by converting sunlight through photosynthesis. They also act as food, providing energy for other organisms.
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.
