State and explain five uses of insects

They help our eco system

Explanation:

PROVIDERS

Insects are in nearly every food chain. Many larger animals—birds, bats, amphibians, and fish—eat insects before they in turn are eaten by predators. The dearth of insects is suspected to be a leading cause of recent declines in bird populations.

DECOMPOSERS

Waste-eating insects unlock nutrients for use by the ecosystem that would otherwise stagnate in dung, dead plants, and carrion. Dung beetles process parasite- breeding and grass-killing cattle dung in 23 months versus the 28 it would otherwise take.

PEST CONTROLLERS

By feeding on crop-threatening pests, predatory insects perform the role of pesticides without chemicals. This cuts pest-control costs and increases yields, saving agricultural industries billions of dollars every year—while reducing toxic pesticide residue on crops.

POLLINATORS

Nearly 90 percent of flowering plant species and 75 percent of crop plant species depend on pollination by animals—mostly insects. Overall, one out of every three bites of food humans eat relies on animal pollination in the production process.

SOIL ENGINEERS

Termites (and ants) can trans- form soil in hot, dry climates. Their tunneling aerates hard ground, helping it retain water and adding nutrients. In some regions, the introduction of termites has turned infertile land into cropland within a year.

Pollination, Food, Silk, Dyes, Dermestids for cleaning skeletons.

Explanation:

Pollination.  Honeybees are among the most important of pollinators, and their efforts result in about 80% of all pollination in the United States.

Food. Honey is made by insects and can be consumed by humans.

Silk.  Most silk is produced from the cocoons of the Silkworm.

Dyes. Many insects provide dyes that are used in cosmetics and for coloring cakes, medicines and beverages.

Dermestids for cleaning skeletons. Carpet beetles feed on almost anything organic and have been used in museums by technicians to clean the skeletons of mammals.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
