Increased nutrients can stimulate an algal bloom in waterbodies, increasing primary production but making the ecosystem less stable. [31] This would raise secondary production and have a trophic cascade effect across the food chain, ultimately increasing overall ecosystem productivity.
An initial increase of net primary productivity, which was not sustained. Faster decline in nitrogen availability in increased CO 2 forest plots. Change in plant community structure, with minimal change in microbial community structure. [48] Enhanced CO 2 cannot significantly increase the leaf carrying capacity or leaf area index of an area.

The research shortened photosynthetic pathways in tobacco. Engineered crops grew taller and faster, yielding up to 40% more biomass. The study employed synthetic biology to construct new metabolic pathways and assessed their efficiency with and without transporter RNAi. The most efficient pathway increased light-use efficiency by 17%. [15]
Thus, increased solar energy (with an abundance of water) at low latitudes causes increased net primary productivity (or photosynthesis). This hypothesis proposes the higher the net primary productivity the more individuals can be supported, and the more species there will be in an area.
Gross primary production (GPP) is the amount of chemical energy, typically expressed as carbon biomass, that primary producers create in a given length of time.Some fraction of this fixed energy is used by primary producers for cellular respiration and maintenance of existing tissues (i.e., "growth respiration" and "maintenance respiration").
The effect of irradiance was significant and constant across all studies, where an increase in irradiance decreased both P:C and N:C. The P:C ratio decreased significantly with warming, but the response to temperature changes was mixed depending on the culture growth mode and the growth phase at the time of harvest.
Productivity in professional and financial services and in information technology grew by 4.3% between 2018 and 2022 compared with gains of 0.9% across construction, manufacturing and retail, food ...
The RIPE project's proof-of-concept study established photosynthesis can be improved to increase yields, [11] published in Science. [12] The Guardian named this discovery one of the 12 key science moments of 2016. [13] Computer model simulations identify strategies to improve the basic underlying mechanisms of photosynthesis and increase yield ...
