How do terrestrial arthropods of the group Hexapoda impact the world's food supply? Provide at least two positive and two negative effects. The terrestrial worms can infect humans and lead to illness and death. The worms can also infect cattle leading to Mad Cow Disease. The worms can churn the soil, which aerates and fertilizes it. The worms can remove harmful organisms from the garden helping the plants. The marine worms trigger harmful algal blooms when there is too much fertilizer in the water. The worms kill small fish destroying the food chain. The worms can be used as bait when going fishing. The worms cut down on the spread of invasive fish. Locusts can consume all the crops for a region leading to starvation. Pine beetles can kill an entire forest. Bees can pollinate crops. Ladybugs can eat garden pests. Spiders like the brown recluse can be harmful to humans. Spiders like tarantulas can kill pets and people. Spiders eat bugs and keep the population down so they do not bother humans. Spiders silk can be used for bandages.
