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.

A wildlife biologists has adopted a number of techniques to protect the Willow Flycatcher, a bird that often nests and feeds in
Ilia_Sergeevich [38]

Answer:

B) Willow Flycatchers can lose eggs to squirrels, weasels, and other predators. The biologist attempts to protect nests by putting metal collars around the base of the windows that keep ground predators from climbing up to reach the nests.

Explanation:  

The dynamic of a species depends on its interaction with other species. So in species management plans, among other aspects, it is important to know the trophic webs in which a species is involved and the interactions of that taxonomic group with the others in the chain.

Top-down techniques take decisions from the most global variables to the most inferior or specific ones. When referring to the trophic web, the most global variables are related to top predators, while the most inferior ones are related to the first levels of the chain.

If the researcher needs to adopt a top-down technique, the most suitable one to choose is to protect the Flycatcher´s nests from predators. Predators are the carnivores in the chain that feeds on the Flycatchers´ eggs. This action will interrupt the link between the superior predators and the flycatchers, allowing this last species to recover its population size.
