16. The base has eight around it and there are eight more connecting the vertices of the base to the apex of the pyramid.
a pyramid as long as there is only one base more specifically a rectangular pyramid
If the pyramid has a triangular sides then truncate each vertex (cut off a small pyramid shape from the vertices).If the pyramid has a quadrilateral base then truncate 3 vertices.If the pyramid has a pentagonal base then truncate 2 vertices.If the pyramid has a hexagonal base then truncate 1 vertex.If the pyramid has a heptagonal base then it is already an octahedron.If the pyramid has an base with 8 or more vertices then slice off the section formed by joining the apex and two vertices from the base which are six apart. This makes the base heptagonal and therefore the shape is an octahedron.
In a stable ecoystem, there should always be more producers than carnivores. For one, there has to be more energy, because your energy flow has to reach the top of the pyramid through your primary, secondary, etc. consumers. There has to be more at the bottom because the organisms at the upper levels have to have a food source. How would the jungle look if there were 100 tigers and only 1 plant?
1 A square pyramid has 1 at the top and 4 round the base, a total of 5. A triangular pyramid has 1 at the top and 3 round the base, a total of 4. The square pyramid has 5 - 4 = 1 extra vertex (round its base).
A food chain shows food energy moving from organism to organism. A pyramid ofnumbers show how many organisms were involved in each level of food chain. Food chains always begin with the sun as the source of energy and the pyramid of numbers always has the producer as the base. Pyramid of numbers have more producers at the bottom than consumers at the top.The similarities are that they both are models and they both have the same organisms. They both have top consumers and they both show how energy is passed down from organism to organism.
A food chain is more relative. A food pyramid is more empirical. The food pyramid is more useful in determining food groups and needs.
As you more up the ecological pyramid, the relative number of organisms present decreases. This means there will be more organisms at the bottom of the pyramid than at the top! At every increasing trophic level (ie primary to secondary to tertiary, etc.), the relative number of organisms will be less as you move up the ecological pyramid! Hope that helps :) Gayyy
There needs to be more organisms at the bottom of the pyramid of numbers because each trophic level requires energy from the level below it, resulting in a decrease in available energy as you move up the food chain. This means that more organisms are needed at lower levels to support the energy requirements of those at higher levels.
A cone has a round base and a pyramid has a base with 3 or more angles.
16. The base has eight around it and there are eight more connecting the vertices of the base to the apex of the pyramid.
Biomass - the total dry weight of the organisms in a trophic levelBiomass Pyramid - a diagram showing the biomass at each trophic level of a food chainA pyramid of biomass shows energy lost in each trophic level while a pyramid of numbers shows the numbers of the organisms in each trophic level
a pyramid as long as there is only one base more specifically a rectangular pyramid
We need more plants than animals in the food pyramid so there is enough food and air to support them
The energy pyramid shows how the amount of useful energy, food, decreases as organisms in that level use it. Even though a lot of energy may be taken in at any level, more energy in the form of food that is available to the next level, is stored on the bottom level and decreases at each level as you move to the top of the pyramid. Thus, there is much less energy to support organisms at the top, so there are fewer in most communities.
An oblique pyramid is a pyramid that does not have its apex aligned with the center of its base. In other words, the pyramid leans more towards one side
A food web shows the complex network of interconnected food chains in an ecosystem, including the various paths of energy flow. On the other hand, a pyramid of biomass represents the relative amount of living organic matter present at each trophic level in an ecosystem, with producers at the base and top predators at the apex. The pyramid of biomass illustrates the quantitative differences in biomass between trophic levels, while the food web provides a more qualitative view of the interactions between different organisms in an ecosystem.
