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.

One type of active transport is called cotransport. In cotransport, the energy available from an ion moving through a transport
kompoz [17]

Answer:

b- It is a spontaneous process.

Explanation:

Passive transport is the type of transport of substances across the plasma membrane that occurs without energy expenditure and occurs spontaneously. There is no energy expenditure during passive transport because substances naturally move from the more concentrated to the less concentrated medium, ie in favor of the concentration gradient.

Substance transport occurs until concentrations inside and outside the cell are equalized.

According to this conceptualization we can conclude that the correct answer to your question is the letter B.
