Insects create the biological basis of all terrestrial ecosystems. They cycle nutrients, pollinate plants, disperse seeds, maintain soil structure and fertility, control populations of other organisms, and provide an important source of food for other taxa. Insects are the only food that sustains certain species of birds, fish and amphibians. Without insect life, the food chain would be severely compromised, as many higher-order animals and birds depend on lower ones for food.
If insects were destroyed, many species would also be eliminated.
