Draw pyramid of number, biomass, and energy for any food chain
Answers
1. A pyramid of numbers represents the number of individuals per unit area of various trophic areas where producers are kept at the base and the tip is occupied by top carnivores.
2. The pyramid of numbers is mostly upright. The members of successive higher trophic levels are higher than the previous one.
3. A higher trophic level has fewer individuals than that of the lower trophic levels. This is because the organisms of the lower level provide the organism of a higher level with food.
4. When food is transferred, only 10 percent of the food is consumed by the higher trophic level organisms.
5. However, a tree that is a large-sized producer can provide food to several herbivores including birds.
Answer:
A pyramid is a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. As such, a pyramid has at least three outer triangular surfaces.
