An important ecosystem function associated with biodiversity is pest control. [23] Control species can suppress pest populations and reduce loss of crop yields without the negative impacts of chemical pesticides. [24] This has economic benefits and maintaining natural pest control is important to humanity's ability to grow crops. [25]
Liverworts have little direct economic importance today. Their greatest impact is indirect, through the reduction of erosion along streambanks, their collection and retention of water in tropical forests, and the formation of soil crusts in deserts and polar regions. However, a few species are used by humans directly.
With such soil fertile soil comes premium forage for livestock which is why South Dakota also comes in top ten for beef, sheep, hog, and honey production. [1] Houdek loam soil is the foundation of life and the economic base for South Dakota. Houdek loam is a symbol that can help increase public awareness and importance of South Dakota's soil ...
Pacific sea nettles, Chrysaora fuscescens. Cnidaria (/ n ɪ ˈ d ɛər i ə, n aɪ-/ nih-DAIR-ee-ə, NY-) [4] is a phylum under kingdom Animalia containing over 11,000 species [5] of aquatic invertebrates found both in fresh water and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites.
Organisms that live freely at the surface, termed neuston, include keystone organisms like the golden seaweed Sargassum that makes up the Sargasso Sea, floating barnacles, marine snails, nudibranchs, and cnidarians. Many ecologically and economically important fish species live as or rely upon neuston.
A mass deposition of Pyrosoma atlanticum carcasses were found along an oil pipeline in West Africa in 2006.. Jelly-falls are marine carbon cycling events whereby gelatinous zooplankton, primarily cnidarians, sink to the seafloor and enhance carbon and nitrogen fluxes via rapidly sinking particulate organic matter.

Cnidarians (jellyfish) Velella, Porpita, Physalia, and Actinecta. Numerous floating cnidarians (jellyfish) live at the ocean's surface, some famous (or infamous) and others rarely seen. Species like Velella sp. (by-the-wind sailor) and Porpita sp. (blue button) are central to the surface food web. They possess symbiotic dinoflagellates in their ...
Economic entomology is a field of entomology, which involves the study of insects that benefit or harm humans, domestic animals, and crops. Insects that pose disadvantages are considered pests . Some species can cause indirect damage by spreading diseases, and these are termed as disease vectors .
