B. There will be more carnivores than any other
organism in an ecosystem.
C. There will be more carnivores than herbivores in an
ecosystem.
D. There will be more producers than herbivores in an
ecosystem

D.There will be more producers than herbivores in an ecosystem

Explanation:

In an ecosystem, organisms feed on one another in order to obtain energy needed for their life processes. The series of chain by which organisms derive energy by feeding on one another is called FOOD CHAIN. A good chain always start with a PRODUCER (an organism capable of synthesizing its own food via photosynthesis). Organisms called HERBIVORES feed directly on the producers, and subsequently CARNIVORES feed on the herbivores.

According to the pyramid of numbers, which shows a graphical display of the number of organisms occupying each trophic level, the producers which are at the bottom of the pyramid are always more in number than any other organism in the food chain. It takes fewer herbivores to consume a large number of producers.

sorry, but you do not have posted the diagram.

the answer is sex-linked recessive.
