Every component of food chain forms trophic level.
Inter-relation between different food chains is known as a food web.
All the chains formed by nutritional relations are used to understand energy flow.
In food chain, energy level increases from lower trophic level to higher trophic level.

Answer 1

The correct answer is In the food chain, the energy level increases from a lower trophic level to a higher trophic level.

Key Points

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.
There are 2 types of food chains, namely the Grazing food chain and Detritus food chain.
Food chains are important because they show the intricate relationships in ecosystems.

Additional Information

All of the interconnected and overlapping food chains in an ecosystem make up a food web. Organisms in food chains are grouped into categories called trophic levels.
The relationship between organisms is interlinked by a food chain. Food web: It is the link between different food chains and presents what species eat in an ecological system.
Energy flow is the flow of energy through living things within an ecosystem.
