:) The 1st trophic level has more energy. The first trophic level consists of producers(plants and algae). They has more energy because they create their own food (photosynthesis). Hope this answer helps :)

In food chain and web what trophic level must you have more of than other?

the primary producer


Why is it that only part of the energy store in one tropics level is passed on to the next level?

Because every organism, upon consuming a resource, must expend some energy in order to digest/process that resource. Thus not all energy is passed from trophic level to trophic level.


Why does the amount of energy decrease as you move up the energy pyramid?

Energy decreases as you move up the energy pyramid due to energy loss at each trophic level through respiration, heat loss, and incomplete digestion. Organisms at higher trophic levels must consume more food to meet their energy needs, resulting in less energy transfer to the next trophic level.


What is needed for an ecosystem to create stability?

An ecosystem needs biodiversity, nutrient cycling, energy flow, and dynamic interactions among its components to create stability. These elements help maintain resilience in the face of disturbances, such as natural disasters or climate change.


Why do different tropic levels have different amounts of energy?

Different trophic levels have different amounts of energy because energy is lost as it moves up the food chain. Organisms at higher trophic levels must consume a larger amount of lower trophic level organisms to obtain enough energy to sustain themselves. This inefficiency in energy transfer limits the amount of energy available at each trophic level.


What trophic level represents the largest biomassin this ecosystem?

The producers, which are usually plants, represent the largest biomass in an ecosystem. They convert sunlight into energy through photosynthesis, providing food for consumers at higher trophic levels.


How is the energy loss from one trophic level to the next reflected in the pyramid of numbers shown in the transparency?

In a pyramid of numbers, the number of organisms decreases at higher trophic levels due to the energy loss as it moves through the food chain. This is because each trophic level must consume more individuals from the level below to meet its energy needs, resulting in a decrease in the total number of organisms as you move up the pyramid. This reflects the decreasing efficiency of energy transfer from one trophic level to the next.


Why must there be more organisms at the bottom of the pyramid of numbers at the top?

There needs to be more organisms at the bottom of the pyramid of numbers because each trophic level requires energy from the level below it, resulting in a decrease in available energy as you move up the food chain. This means that more organisms are needed at lower levels to support the energy requirements of those at higher levels.


Why must there be more organisms at the bottom of the pyramid of numbers than at the top?

There must be more organisms at the bottom of the pyramid of numbers because these organisms, typically producers like plants, form the foundational level of the food chain. They convert sunlight into energy through photosynthesis, providing the primary energy source for the entire ecosystem. As you move up the pyramid to higher trophic levels, such as herbivores and carnivores, the number of organisms decreases due to energy loss at each level, primarily through metabolic processes and heat. This energy loss limits the number of individuals that can be supported at higher trophic levels.


Why is so little of the energy from one trophic level transferred up to the next trophic level?

Energy is lost as heat through respiration, metabolism, and waste production as it moves up the food chain. Each trophic level can only convert about 10% of the energy it receives into biomass that is available to the next trophic level, resulting in an overall inefficiency in energy transfer.


Why must there be more biomass at the lowest trophic level?

Consumers do not use 100% for growth as some of the energy they use is used to maintain body temperature but also to contract muscles. As energy cannot be created or destroyed but only transferred the amount of energy as you go up the chain must decrease, so the primary producer must have the most biomass.


What does auto trophic mean?

auto must be meaning automatic,they can make there own food and trophic must be ecology of or involving the feeding habits or food relationship of different organisms in a food chain. by sharandeep bose
