Plants are the primary producers in most terrestrial ecosystems and form the basis of the food web in those ecosystems. [82] Plants form about 80% of the world biomass at about 450 gigatonnes (4.4 × 10 11 long tons; 5.0 × 10 11 short tons) of carbon. [83]
One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
In the simplest scheme, the first trophic level (level 1) is plants, then herbivores (level 2), and then carnivores (level 3). The trophic level equals one more than the chain length, which is the number of links connecting to the base. The base of the food chain (primary producers or detritivores) is set at zero.
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 estimated total world production for eggplants in 2022 was 59,312,600 metric tonnes, up by 1.0% from 58,705,398 tonnes in 2021. [1] China was by far the largest producer of eggplants, accounting for nearly 65% of global production at 38,284,897 tonnes. Dependent territories are shown in italics.
