Describe the information displayed by ecological pyramids Use all three pyramids (number, biomass, and energy in your answer.​
kumpel [21]

Explanation:

Edit

An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.

A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels. Energy pyramids are necessarily upright in healthy ecosystems, that is, there must always be more energy available at a given level of the pyramid to support the energy and biomass requirement of the next trophic level.

A pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms. There is also a pyramid of numbers representing the number of individual organisms at each trophic level. Pyramids of energy are normally upright, but other pyramids can be inverted or take other shapes.

Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.

The forelimbs of humans, cats, and bats have a number of detailed similarities in their construction. what best explains these s
bulgar [2K]
Evolution :).

Descent with modification helps to explain anatomical similarities among certain species. The bones of the forelimbs of humans, cats, and bats (you can add in penguins, alligators, and more) are used in different ways but have similar structures.

The best explanation is that these animals have a common ancestor. With new generations, new species emerged by natural selection from different populations, and with this, the bones become better for different tasks.

The forelimbs and other such structures with anatomical similarities due to a common ancestor are called homologous structures.
