Summary Introduction

To review:

The hypothesis that supports the fact that different ecosystems like tropical rainforests and desert have five and three trophic levels in their food webs respectively.

Introduction:

Different ecosystems contribute different net primary production (NPP) to the earth’s net primary productivity. Depending upon the primary producers in a region, the NPP of that region gets affected. Generally, the NPP increases with the decrease in latitudes. The tropical rainforests have higher NPP. The trophic levels depend upon the amount of NPP of an ecosystem.
