Which group in the food web has the greatest biomass?
Which group of organisms in this food web has the greatest available energy?
Food Chains and Energy Flow
|10%||the amount of energy passed on at each level in a food chain/energy pyramid|
|Which group of living things receives the greatest amount of energy from the sun?||green plants (producers/autotrophs)|
|Which group of consumers receives the most energy in a food chain?||plant eaters (herbivores)|
Which level contains the least biomass?
Why do tertiary consumers have the least biomass?
With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass.
What happens to biomass as you move up?
A biomass of organisms at different levels of a food chain can be shown in a pyramid of biomass. Some material and energy is passed out as waste by the organism. Some of the energy is used for growth. Therefore, biomass and energy decreases as you move up the biomass pyramid from one trophic level to the next.
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.
How do you explain a food chain to a child?
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.
How many types of food chains are there?
