How can the abundance and diversity of living beings in the tropical forests be explained?
The biodiversity of these ecosystems can be defined by the great availability of the main abiotic factors for photosynthesis. As these factors are abundant plants can perform maximum photosynthetic activity, living and reproducing simply. With a great amount and diversity of producers (autotrophs), the consumers (heterotrophic animals and microorganisms) also have abundant food and a difficult food web emerges creating many different ecological niches to be explored. So the appearance of varied living beings as well as the existence of large populations is possible.
