In an ecosystem, energy flows from producers to consumers through trophic levels. If producers provide 1500 calories of energy to first-level consumers (herbivores), these consumers typically convert only about 10% of that energy into biomass, passing approximately 150 calories to the second-level consumers (carnivores). Following the same efficiency, the second-level consumers would then pass about 15 calories to the third-level consumers, which are the apex predators. Thus, the third-level consumers receive a significantly reduced amount of energy due to the energy loss at each trophic level.
Only about 10% is passed from level to level. In this case it is 10% of 1500 calories or 150 calories. This the reason why there has to be many, many producers and why there are only a few consumers. And why you will only see a few eagles or wolves at the very top of the pyramid.
Consumer because a consumer eats plants and animals for energy Producers create their energy through photosynthesis
A small biomass of producers can support a consumer population when there is enough energy available from the producers to sustain the consumer species. This relationship is dependent on factors such as energy transfer efficiency and the specific nutritional requirements of the consumer species. If the producers can replenish their biomass efficiently and there is minimal energy loss along the food chain, a small biomass of producers can indeed support a consumer population.
A producer is always at the beginning of a food chain. A producer will always be a plant. A primary consumer eats the producer. The secondary consumer eats the primary consumer. The scavenger comes next (if it gets there before the decomposer.) The decomposer will always be last. Example: (where there is a scavenger) grass --> rabbit --> fox --> vulture --> mushroom producer, primary consumer, secondary consumer, scavenger, decomposer

Consumer
they provide energy or calories
They make their own energy, instead of consuming another consumer for their energy.
Producers Consumer Decomposer
Lungfish are a consumer as they need food to survive. Producers recieve most of their energy from the sun
