Phytoplankton obtain energy through the process of photosynthesis and must therefore live in the well-lit surface layer (termed the euphotic zone) of an ocean, sea, lake, or other body of water. Phytoplankton account for half of all photosynthetic activity on Earth. Thus phytoplankton are responsible for much of the oxygen present in the Earth’s atmosphere – half of the total amount produced by all plant life. http://en.wikipedia.org/wiki/Phytoplankton
Marine Biodiversity Strongly Linked to Ocean Temperature
ScienceDaily (July 29, 2010) — In an unprecedented effort that will be published online on the 28th of July by the international journal Nature, a team of scientists mapped and analyzed global biodiversity patterns for over 11,000 marine species ranging from tiny zooplankton to sharks and whales. The researchers found striking similarities among the distribution patterns, with temperature strongly linked to biodiversity for all thirteen groups studied. These results imply that future changes in ocean temperature, such as those due to climate change, may greatly affect the distribution of life in the sea.

Habitat fragmentation and its lasting impact on Earth’s ecosystems / March 2015

“There are really only two big patches of intact forest left on Earth”

... the studies showed that when patches of forest become smaller and more isolated, the abundance of birds, mammal, insects and plants decreases in kind — those pressures reduced the species’ ability to persist... On average... fragmented forests lose more than half of their species within just 20 years; in the one experiment that’s still ongoing after more than two decades, the losses are continuing to compound.

THE BIOSPHERE

The biosphere is integral to the functioning of earth systems. First, the present atmosphere is the product of respiration on the part of plants, which receive carbon dioxide and produce oxygen. In addition, transpiration, a form of evaporation from living organisms (primarily plants), is a mechanism of fundamental importance for moving moisture from the hydrosphere through the biosphere to the atmosphere....
