Flow of Energy
Grade 6 Science Worksheets
The flow of energy refers to how energy moves and changes from one form to another. It’s similar to how water flows in a river, it starts at a high point and flows down to a lower point.

"We really love eTutorWorld!"
"We really love etutorworld!. Anand S and Pooja are excellent math teachers and are quick to respond with requests to tutor on any math topic!" - Kieran Y (via TrustSpot.io)
"My daughter gets distracted easily"
"My daughter gets distracted very easily and Ms. Medini and other teachers were patient with her and redirected her back to the courses.
With the help of Etutorworld, my daughter has been now selected in the Gifted and Talented Program for the school district"

Understanding the Flow of Energy.
The energy can flow through different pathways and systems, such as food chains and energy cycles.
For example, the sun sends energy to the Earth in the form of light and heat. This energy is then used by plants through photosynthesis to convert it into chemical energy, which is stored in their leaves. This energy is then passed on to animals that eat the plants, and it is used to fuel their movement and growth.
It’s important to note that energy can’t be created or destroyed, only transformed from one form to another. This is known as the law of conservation of energy.
Understanding the flow of energy is important because it helps us understand how energy is used in different processes and how it moves through different systems. It also helps us understand how energy resources are used, and how they can be conserved and utilized most efficiently.
Flow of Energy – Trophic Level and Food Chains
One way to understand the flow of energy is by looking at trophic levels and food chains.
A trophic level is a position occupied by group of organisms that have the same main source of energy in a food chain.
There are several trophic levels, but the most common are:
Producers: These are organisms that can produce their own food, such as plants. They use energy from the sun to make their own food through photosynthesis.
Consumers: These are organisms that cannot produce their own food and must eat other organisms to survive. There are different types of consumers such as herbivores, which eat plants, and carnivores, which eat other animals.
Decomposers: These are organisms that break down dead plants and animals, and recycle nutrients back into the ecosystem.
“There have been times when we booked them last minute, but the teachers have been extremely well-prepared and the help desk at etutorworld is very prompt.
Our kid is doing much better with a higher score.”

A food chain is a linear sequence of organisms that shows how energy flows through an ecosystem, starting with the producers and ending with the decomposers. Each organism in a food chain is a source of energy for the next organism.
For example, in a simple food chain, energy from the sun is used by plants to make their own food through photosynthesis. This energy is then passed on to herbivores that eat the plants, and then to carnivores that eat the herbivores. The energy is eventually lost as heat or used by decomposers to break down dead plants and animals.
It’s important to note that energy is lost at each step of the food chain, that’s why in most ecosystems, the number of organisms decreases as you move up the food chain.
Understanding the flow of energy in trophic levels and food chains allows us to understand how energy is transferred within an ecosystem, how it is used and how it is lost.
It also helps us understand the interdependence of different organisms within an ecosystem and how they rely on each other to survive.

How does energy flow through a food chain?
Energy flows through a food chain by being passed from one organism to another. For example, energy from the sun is used by plants to make their food through photosynthesis. This energy is then passed on to herbivores that eat the plants and then to carnivores that eat the herbivores. The energy is eventually lost as heat or used by decomposers to break down dead plants and animals.
