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.
Answer:
the same number of cells in both.
Explanation:
Nutrient broth is a general purpose medium that can be used to cultivate different variety of both fastidious and non-fastidious microorganisms.
Nutrient broth is known to contain or compose of simple peptone and a beef extract.
It is known to be used for bacteria that will not form colonies on a solid surface.
Nutrient broth can be prepared through this following steps
* Add 13g of nutrient broth powder in 1L of distilled water.
* Mix and dissolve them completely.
* Pour them into the final containers (eg. conical flask)
* Sterilize by autoclaving at 121°C for 15 minutes.
In this case, since the 100 ml and 1000 ml is prepared using the same method, it is expected to have the same number of cells in the same volume of the broth.
Answer:
Early prophase: the DNA and centrioles duplicate and the centioles move and form the mitotic spindle. Middle prophase: microtubles from the spindle attach to the chromosomes. Late prophase: the chromosomes move to the equatorial plane.

Answer:
Explanation:
In mitosis, when a single cell divide into two daughter cell and each daughter cells have a copy of chromosomes, there must first be the copying of the chromosomes from the parent cell and after that the chromosomes are separated or there is separation of chromosomes into each of the daughter cells.

For APEX: A decline in the native species of beetle.
