Detritus - Wikipedia

Detritus occurs in a variety of terrestrial habitats including forest, chaparral and grassland. In forests the detritus is typically dominated by leaf, twig, and bacteria litter as measured by biomass dominance. This plant litter provides important cover for seedling protection as well as cover for a variety of arthropods, reptiles and amphibians.

Thus a pressure gradient from the area of photosynthesis (source) to the region of growth or storage (sink) is established in sieve tubes that would allow solution flow.

ADVERTISEMENTS: Decomposers are the final step in the food chain and they reduce the organic matter into inorganic forms so that it is once again available to the producers. The upper layer of soil is the main site for the action of decomposers. In this way, decomposers provide energy and nutrients to the producers. The [.]

Water and Mineral Transport

So the limits on water transport limit the ultimate height which trees can reach. The tallest tree ever measured, a Douglas fir, was 413 ft. (125.9 meters) high. Root Pressure When a tomato plant is carefully severed close to the base of the stem, sap oozes from the stump. The fluid comes out under pressure which is called root pressure.

Insects as a Nitrogen Source for Plants - PubMed Central (PMC)

Jul 31, 2013 · Another major reason for the nitrogen deficit is that some nitrogen is immobilized within decaying plant material. Plant litter is high in nitrogen-containing polymers such as lignin, which is recalcitrant to decomposition, and as such, plant detritus contains large quantities of immobilized nitrogen .

Heterotroph - Wikipedia

A heterotroph (/ ˈ h ɛ t ər ə ˌ t r oʊ f, -ˌ t r ɒ f /; Ancient Greek ἕτερος héteros = "other" plus trophe = "nutrition") is an organism that cannot produce its own food, relying instead on the intake of nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are primary, secondary and tertiary consumers, but not producers.
