Question: What Is Food Chain For Class 5?

What is a food chain Class 10?

A food chain is a series of organisms where all the organismsare dependent on next organism as a source of food.

The series of organism take part at various biotic levels to form a food chain.

Each step of the food chain forms a tropic level.

Tertiary consumers (larger carnivores) form the fourth tropic level..

What is a food chain easy definition?

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. … In a predator chain, a plant-eating animal is eaten by a flesh-eating animal.

What is food chain with example?

A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.

What is a food chain explain with 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.

What is food chain types?

The transfer of food energy from the producers, through a series of organisms (herbivores to carnivores to decomposers) with repeated eating and being eaten, is known as food chain. … In nature, basically two types of food chains are recognized – grazing food chain and detritus food chain.

Why is food chain important?

A food chain shows how energy is transferred from one living organism to another via food. It is important for us to understand how the food chain works so that we know what are the important living organisms that make up the food chain and how the ecology is balanced.

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 is the food chain of grasslands?

The grass, deer and tiger form a food chain (Figure 8.2). In this food chain, energy flows from the grass (producer) to the deer (primary consumer) to the tiger (secondary consumer). A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3).

What is a food chain for kids?

The term food. chain describes the order in which organisms, or living things, depend on each other for food. Every ecosystem, or community of living things, has one or more food chains. Most food chains start with organisms that make their own food, such as plants. Scientists call them producers.

What is food chain with diagram?

Normally, food webs consist of a number of food chains meshed together. Each food chain is a descriptive diagram including a series of arrows, each pointing from one species to another, representing the flow of food energy from one feeding group of organisms to another.

What is the correct food chain?

The process of transfer of energy from producers through a series of organisms, i.e., from primary consumers to secondary consumers and from secondary consumers to tertiary consumers by process of eating and being eaten constitute a food chain. The correct food chain is phytoplankton >> zooplankton >> fish.

What is difference between food chain and food web?

A food chain is a basic network that shows the linear flow of nutrients and energy from one trophic level to another. A food web is a multitude of food chains that are interconnected at many trophic levels. Furthermore, a food web accurately represents all the various food chains that exist in an ecosystem.

What are the 4 food chains?

Roughly speaking, these levels are divided into producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers. 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.
