Pyramids of Numbers show the numbers of species involved in a simple food chain. The problem with pyramids of Numbers is that in some events the pyramid is not pyramid shaped. For example, When using aphids and tomato plants as an example, there will be hundreds of aphids feeding on the tomato plant, giving the pyramid an inverse-pyramid shape. Pyramids of Biomass, however, do not take into account the numbers involved, but rather the mass. This is not only sometimes of a higher scientific value, but in most cases this will form a pyramid.
No, green algae would not be found at the top of an energy pyramid. They are producers that form the base of the pyramid, converting sunlight into energy through photosynthesis. Organisms higher up in the pyramid, like herbivores and carnivores, consume the green algae for energy.
No, producers are not always the largest level in a trophic pyramid. Producers form the base of the pyramid, with primary consumers feeding on them, and subsequent trophic levels following. The largest level in a trophic pyramid can vary depending on the ecosystem and the specific food web dynamics at play.
A pyramid of numbers cannot always be to scale because it represents the number of organisms at each trophic level, which can vary significantly in size and biomass. For instance, a single large predator may consume many smaller prey, leading to a skewed representation if actual numbers are used. Additionally, certain ecosystems may have a high number of primary producers but fewer higher-level consumers, resulting in a pyramid that appears disproportionate when scaled. Thus, while it visually illustrates relationships in the food chain, it may not accurately reflect the biomass or energy flow.
The pyramid of energy always remains upright because energy diminishes as it moves up trophic levels in an ecosystem. This is because energy is lost as heat during each transfer between trophic levels, leading to a decrease in available energy for higher trophic levels.

No. For example, consider the vertices of a tetrahedron (triangle-based pyramid).
In an energy pyramid, the producer layer always has the most energy because producers, such as plants, are able to convert sunlight into energy through photosynthesis. This energy is then passed on to consumers in higher trophic levels through the consumption of producers.

Not always because as for example 2*19 = 38

The pyramid of numbers is not a true pyramid shape because it represents the number of organisms at each trophic level rather than biomass or energy. In many ecosystems, the number of individual organisms can be greater at lower trophic levels while higher levels may contain fewer, larger organisms, leading to an irregular shape. Additionally, some ecosystems, such as those with a few large producers and many small consumers, can result in inverted pyramids. Thus, the pyramid of numbers can be skewed and does not always reflect a true pyramidal structure.

Nutters who believe in pyramid energy. Or if the pyramid is a food chain, producers.
A triangle.
Producers, such as plants and algae, are always at the bottom of an energy pyramid because they are the foundation of the food chain, converting sunlight into energy through photosynthesis. They form the base of the pyramid and provide energy for all other organisms in the ecosystem.
No. For example, the GCF of 8 and 12 is 4. The GCF of 12 and 18 is 6. The Greatest Common Factor of two even numbers will always be even, but it will not always be 2.
