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.
What are the 5 steps in a food chain?
- 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)
What are the steps of the food chain?
Organisms in food chains are grouped into categories called trophic levels. 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.
What is food cycle explain with 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 food chain What are the 3 main parts of a food chain explain with diagram?
The food chain also explains the feeding pattern or relationship between living organisms. Trophic level refers to the sequential stages in a food chain, starting with
producers at the bottom, followed by primary, secondary and tertiary consumers
. Every level in a food chain is known as a trophic level.
How do you explain a food chain to a child?
A food chain
shows how each living thing gets its food
. 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.
What is food chain and 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. BiologyFood Chain.
Who eats eagle in food chain?
Eagles are apex predators at the top of the food chain, which means they have no natural predators. However, unattended eaglets and even weakened adult eagles may be eaten by other predators such as
bears, wolves, lions, alligators, ravens, and great horned owls
.
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.
What are the three main steps in a food chain?
Answer: Various steps in a food chain are known as
trophic levels
. The first trophic level is of producers. The second trophic level is of primary consumers also known as herbivores, third of carnivores, or secondary consumers, fourth is of tertiary consumers also known as top carnivores.
What are the three major steps in a food chain?
Answer : Various steps in a food chain are known as
trophic levels
. The first trophic level is of producers. The second trophic level is of primary consumers also known as herbivores, third of carnivores, or secondary consumers, fourth is of tertiary consumers also known as top carnivores.
What is food chain in simple words?
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.
What is food chain give an example of a food chain?
Each living thing is a part of multiple food chains – for example, grass is a part of the food chain:
grass → grasshopper → frog → snake → eagle, and also of the food chain: grass → deer → tiger
. All of the interconnected and overlapping food chains in a habitat make up a food web.
Where does the food chain start from?
A food chain always starts with
a producer
. This is an organism that makes its own food. Most food chains start with a green plant, because plants can make their food by photosynthesis. A living thing that eats other plants and animals is called a consumer.
How does a food chain show interdependence?
A food web is a network of interconnected food chains . It shows the energy flow through part of an ecosystem . In a food web,
changes in the population of one organism have an effect on the populations of other organisms
. This is called interdependence.

What is food chain class4?
food chain is
a transfer of food energy from some plants to an animal and then to another animal
. green plants make their own food by photosynthesis. then animal eat plants and another animal eat animals. this process is called food chain.
Who eats lion?
Do lions have predators? No predators hunt lions to eat them; however, they do have a few natural enemies, such as
hyenas and cheetahs
. Hyenas compete with lions for food and often try to steal their kills.
