What do crops rely on insects for? How does this affect humans?
What is a food chain? What is a food web? and what is the difference?
Answers
Answer:
plants rely on insects for pollination
Though some plants are self-pollinated or wind pollinated, many flowering plants rely on insects to transport their pollen to other flowers, ensuring fertilization. ... Without bees, many of the plants we rely on wouldn't be able to reproduce—and produce many of the fruits we eat, such as apples and blueberries.
insects are beneficial to humans and the environment, not detrimental. Without insects, the environment could not function as it does, yet few of us have considered how these numerous and varied organisms actually affect our lives.

One of the most important services insects provide is pollination. Though some plants are self-pollinated or wind pollinated, many flowering plants rely on insects to transport their pollen to other flowers, ensuring fertilization. Insects visit flowers to collect nectar, but many have specialized anatomy for carrying the pollen they inevitably brush up against. Bees commonly collect pollen in “baskets” formed by stiff hairs on their hind legs or abdomens.
food chain
food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. A food chain also shows how the organisms are related with each other by the food they eat. Each level of a food chain represents a different trophic level.
food web
food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Another name for food web is consumer-resource system.
difference between food chain and food web
food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected
