What happens to the relative number of organisms as you move up an ecological pyramid?

Answer 1

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 :)

Answer 2

I assume you mean food chain, and will answer the question as such. A food pyramid is something primarily regarding human nutrition. As you go up a level in food chain, say from salmon to grizzly bear, the number of organisms decreases as competition for food increases. Even if there were theoretically more predators than prey, the trend would quickly shift because as prey grows scarce and predators die off from starvation.
