What is used to indicate the flow of energy in a food chain or web
The flow of energy occurs from the sun in photosynthetic organisms. Another examples is a food chain with the flow of energy from through organisms from a producer. The flow of materials describes the movement of materials or components.
food chain
It is called a food chain.
grass - grasshopper - frog - snake.
science
The large omnivore may reverse the flow of energy in a food chain.
The arrows in a food chain indicate the direction of energy flow from organism to organism.
To most people it is true that in the biosphere there is a one way flow of energy. This is thought of in terms of the food chain.
There are several different factors that control the primary productivity of energy and biomass flow. Energy flow is the amount of energy that moves through a food chain. The energy input, or energy that enters the ecosystem, is measured in Joules or calories. Accordingly, the energy flow is also called calorific flow. In the study of energy flow, ecologists try to quantify the importance of different species and feeding relationships.
It can be argued that humans are the dominant species on Earth due to our advanced cognitive abilities and technological advancements. However, in terms of sheer numbers and impact on the environment, some may consider bacteria or insects as the dominant species.
