One of the three diagrammatic representations of the ecosystem used in ecology is a pyramid of numbers. The total number of species at every level of the food chain can be seen in such a picture. Since the biomass is not taken into account, it does not necessarily have a regular pyramidal shape.
The ecological pyramids are diagrams with a pyramidal structure that explain the relationships and energy flow between various species in an ecosystem. The producers, which are the species that produce food or energy for their life, make up the lowest layer of the pyramid. Other species, known as the consumers, make up the layer above the producers and consume the producers. When a result, there is only a slight energy waste in the environment as energy moves from producers to consumers. Each level of this phenomenon's food chain is referred to as a trophic level.
A single large producer At the first trophic level would be shown As a large measure in the pyramid of biomass by a small measure in the pyramid of numbers.
Explanation:
I Got The Question Wrong but this is the correct answer.
The correct answer is option A, It grows healthy crops.
Because the loess soil is very fertile due to its ability to exchange cations and porosity.
Due to cation exchange capacity the plants easily absorbs nutrients from the soil and due to porosity the soil holds the water, oxygen and nutrients which is absorbed by the roots of the plants for their nourishment.
The myelin sheath is a layer that forms an insulating and protective coating around nerves. This sheath is fundamental for the functioning of the nervous system.
During neuronal firing, the part of the neuron that acts as an insulator and conductor to speed the electrical impulse as it travels down the axon is the MYELIN SHEATH.
This myelin layer is fundamental for the efficiency and velocity of the transmission of electrical impulses along nerves.
The damage of the myelin sheath is associated with different neuronal disorders (e.g., multiple sclerosis).
