World Atlas of Biodiversity
Mappa geografica biodiversità terrestre e marina.
Terrestrial biodiversity:
Terrestrial ecosystems extend over little more than one quarter of the Earth's surface but they are more accessible than aquatic habitats and so are far better known. The land supports fewer phyla than the oceans but most of the global diversity of species, and is characterised above all by an extensive cover of vascular plants, with associated animals and other groups of organisms.
Marine biodiversity:
Most of the planet is covered by ocean waters whose average depth is four times the average elevation of the land, making the open sea by far the largest ecosystem on Earth. Despite this volume, marine net primary production remains similar to or less than that on land because photosynthesis in the sea is carried out by microscopic bacteria and algae restricted to the sunlit surface layers (plants are virtually absent).

worthington-biochem
The following has been excerpted from a very popular Worthington publication which was originally published in 1972 as the Manual of Clinical Enzyme Measurements. While some of the presentation may seem somewhat dated, the basic concepts are still helpful for researchers who must use enzymes but who have little background in enzymology.
