How are insects valuable to humans? |
They provide many useful products and are important pollinators of fruits and vegetables on which we're reliant. |
What percent of insects are harmful? |
5% |
Why are insects successful? |
They have an exoskeleton that protects them from the outside world, they are small so they can easily hide from predators, they are capable of flight, they change forms during their life (metamorphosis), and they produce a large amount of offspring. |
