AP BIOLOGY

Detailed explanation-1: -At the lowest trophic level, the primary producers, there is the least amount of biomass and as the trophic levels increase the biomass increases. This is known as an inverted pyramid. A pyramid such as this one occurs in aquatic ecosystems because the turnover rates of the primary producers are much higher.

Detailed explanation-2: -In general, the higher the trophic level (increasingly apex predators), the lower the biomass. Therefore, the lowest trophic level has the greatest biomass, and those are the producers.

Detailed explanation-3: -As a result, tertiary consumers have the least amount of energy and are therefore at the top of the pyramid (the smallest part). Ecological pyramids can illustrate changes in the numbers, biomass, or energy content of organisms at each level.

Detailed explanation-4: -Terrestrial biomass The level with the least biomass are the highest predators in the food chain, such as foxes and eagles. In a temperate grassland, grasses and other plants are the primary producers at the bottom of the pyramid.

Detailed explanation-5: -The trophic level that has the least biomass is usually the tertiary consumers. Tertiary consumers are at the top of the food web and subsequently have the least access to energy, according to the 10% rule. Producers access energy directly from the sun or from chemicals, so they get 100% of the energy available.
