Which of the following explains the term pyramid of numbers?
Answer Details
Pyramid of numbers is a graphical representation of the number of organisms present at different levels in a food chain. It shows the relationship between the number of organisms at each trophic level, starting from the producers at the base and moving up to the top predators.
The correct option that explains the term pyramid of numbers is: "Progressive decrease in the number of individuals from lower to higher trophic level." This means that the number of organisms decreases as we move from the lower to the higher trophic level. For example, there are more plants than herbivores, and more herbivores than carnivores. This results in a pyramid shape when represented graphically.
Therefore, the pyramid of numbers provides a simple and clear way to understand the structure of an ecosystem and the flow of energy through different levels of the food chain.
