Answer:
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.
FOOD CHAIN: Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.
FOOD WEB:A food web is all of the food chains in an ecosystem. Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid.
DIFFERENCE: The main difference between food chain and web are as follows:-1) Food chain is a single path of plants and animals so that they eat each other and energy flows accordingly while food web is a collection of many food chains.
2) Food chains shows only one chain of connected plants and animals with their food habits while food web shows the various different plants and animals in an ecosystem.
3)Food chain is a model of plants and animals which shows the flow of energy among organisms while food web is a connection between food chains and what species eat them.
4) Food chain has no effect on improving the adaptability and competitiveness of organisms while food web improves them.
5) The food chain is the pattern that energy uses to transmit to producers to decomposers while food web is a series of related food chains displaying the movement of energy.
MECHANICAL ENERGY: Mechanical energy is the energy possessed by an object due to its motion or its position.
