Consumers. The bottom level is only producers because nothing is below them. Producers, such as grass, provide nutrients for consumers but do not require anything else to live except sunlight and water.
All except the base, which is a square.
Energy and matter (mass) move through ecosystems from the bottom of the pyramid to the top. The bottom contains most of the matter and therefore the most energy. About 10% is passed to the second level. About 10% of that 10% is passed to the third level. Most ecosystems have three levels as there is not enough energy for a fourth level. Except in tropical rainforest they are fourth levels but no where else.
Yes, because the number of sides of a pyramid is equal to the bottom face's number of edges times 2. Any number multiplied by two except zero is even.
Because autotrophs use photosynthesis (The process of how plants create energy from carbon dioxide), they create the energy and food heterotrophs need to live. There is a thing called an energy pyramid, which is somewhat similar to a food chain or food web. On each "level" of the pyramid, the amount of energy passed through each animal has decreased by 10%, making the original autotroph the organism that has the most energy.The organism in the food web with the most energy is the autotroph.
The sun.
It gets converted into energy.
no, that is not true, it obvious that pyramid and prism are not the same(except they are both 3D shapes).
total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides
A tetrahedron is shaped like a pyramid, except it has 3 edges on the bottom instead of four. 3 points on the bottom to make the 3 bottom edges, plus one more point up top makes 4 points. 3 faces on the sides, plus the face on the bottom makes 4 faces. : )

A trapezium, except that when it goes through the apex, it becomes a triangle. If the pyramid is a right pyramid, then the cross sections will be isosceles.
All except the base are always triangles; the shape of the base gives the name to the pyramid; eg a pentagonal pyramid has a pentagon as the base and five triangular faces; a triangular pyramid has three triangular faces and also has a triangle for the base.
