Answer:
A food chain only just follow one path as animal find food.
A food web only connected by the plant and animal.
Explanation:
Food chain is that chronological process that show energy of the organism to the other,that energy flow the specific path.
Food chain is the single way to the producers and consumers, animal food travels different around level.
Food chain begins the producer and that eaten by the primary consumer,food chain as the start with a green plant as the producer .
food chain very important the survival of the species,food chain is used in ecological modeling food chain complex network of animals.
Food web is natural inter section representation of ecological community,food web is consumer resource system.
Food web is also limited representation of ecosystem species same predators in a food web.
food web is a complex relation,patterns in the structure of real food web networks,food webs using a network theory.
Food web are the feeding connections in an the ecological community, food web is the collection of network and cycle.

Answer: Option (B) and (F)
Explanation:
Pressure and Density, both are inversely proportional to the height.
The air molecules are mostly present near the surface because of its higher density and the gravitational force that forces them to accumulate near the earth's surface. And as we go up, these air molecules gradually decreases in number and their density also becomes very less, as a result of which the pressure and density both subsequently reduces.
Thus, the correct options are mentioned above, i.e the pressure as well as density both decreases with the increasing height.
