Energy flow in an ecosystem can be illustrated with a food web. For every step up in an ecosystem -- producer to primary consumer, for example, only about 10% of the biomass is conserved (a 200 pound cow would likely consume 2000 pounds of grass) . This means that there is a significant amount of energy lost between each trophic level. This explains why there are beyond trillions and trillions of krill (small aquatic organisms) in the oceans, but only a few blue whales.
Energy flows through an ecosystem via trophic levels, where energy is transferred from one level to the next as organisms are consumed. Trophic structure represents the hierarchy of feeding relationships within an ecosystem, showing the flow of energy from primary producers to consumers at different trophic levels. The efficiency of energy transfer decreases as it moves up the trophic levels due to energy loss through respiration, resulting in less energy available for organisms at higher trophic levels.

The lowest trophic level of any ecosystem is occupied by the consumers?
This statement is incorrect. The lowest trophic level in an ecosystem is occupied by the primary producers, such as plants and algae, that create energy through photosynthesis. Consumers occupy higher trophic levels and feed on the organisms at lower trophic levels.
What are organisms in the lowest trophic level of an ecosystem?
Organisms in the lowest trophic level of an ecosystem are typically primary producers, such as plants and algae. These organisms convert sunlight into energy through photosynthesis, forming the basis of the food chain and providing energy for all other organisms in the ecosystem.
Why do biologists measure the number of trophic levels in ecosystem?
Biologists measure the number of trophic levels in an ecosystem to understand the flow of energy and nutrients through the food chain. It helps to identify the efficiency of energy transfer between different organisms and how changes in one trophic level can impact the entire ecosystem's stability and biodiversity. Tracking trophic levels also aids in predicting how disturbances or human activities may affect ecosystem dynamics.
What can you conclude about a ecosystem with many trophic levels?
it is a stable ecosystem
what is meant by trophic levels?
answer
What moves through organisms at each trophic level of an ecosystem?
nutrients
Besides energy what moves through the organism at each trophic level of an ecosystem?
nutrients
The lowest trophic level of any ecosystem is occupied by the consumers?
This statement is incorrect. The lowest trophic level in an ecosystem is occupied by the primary producers, such as plants and algae, that create energy through photosynthesis. Consumers occupy higher trophic levels and feed on the organisms at lower trophic levels.
The lowest trophic level of any ecosystem is occupied by organisms such as?
The lowest trophic level of any ecosystem is occupied by primary producers, such as plants and algae. These organisms convert energy from the sun into organic compounds through photosynthesis, forming the base of the food chain for other organisms.
An organism's position in the sequence of energy transfers in an ecosystem is known as its what?
An organism's position in the sequence of energy transfers in an ecosystem is known as its trophic level. This indicates the organism's position in the food chain and its role in energy flow through the ecosystem.
What are organisms in the lowest trophic level of an ecosystem?
Organisms in the lowest trophic level of an ecosystem are typically primary producers, such as plants and algae. These organisms convert sunlight into energy through photosynthesis, forming the basis of the food chain and providing energy for all other organisms in the ecosystem.

What does a number pyramid tell you about an ecosystem?
A number pyramid in an ecosystem illustrates the relative abundance of different trophic levels within the food chain. It shows that the number of individuals decreases as you move up the pyramid due to energy loss from one trophic level to the next. This helps us understand the structure and dynamics of energy flow within the ecosystem.
What are the dynamics of any ecosystem?
two major process 1 = cycling of nutrient 2= chemical energy (food)
Which does the trophic structure of a community describe?
The trophic structure of a community describes the feeding relationships and energy flow between different species within an ecosystem. It shows how energy is transferred through the food chain, from producers to consumers at different trophic levels. This structure helps illustrate the flow of nutrients and energy within an ecosystem.
What is energy that is lost at each trophic level of an ecosystem is replenished?
Energy that is lost at each trophic level of an ecosystem is replenished by the producers. The producers get it from the sun.
What is the new trophic model?
Well the trophic model is like the pyramid (Food Chain).But the difference is that trophic model's change every time you go to a different ecosystem.(Ecosystem Definition - http://dictionary.reference.com/browse/ecosystem)Pristine Ecosystems have a wine shaped trophic model and Near - Pristine Ecosystems have a upside down wine shaped trophic model. Human affected ecosystems have a triangle trophic model.
