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.
-- Earth is one planet is a "Solar System", that consists of everything
that's gravitationally hooked to the Sun ... one star. This system contains
7 other other significant planets, more than 100 of their moons, and huge
numbers of comets, asteroids, dwarf planets, and countless bodies in a
giant shell that are so small and so far away that we can only see a few
of them so far. Every one of these items orbits the sun. The ones that
are farthest out may take thousands of years to complete one orbit.
That's the 'kingdom' of ONE star ... the sun.
-- It's very likely that there are similar gatherings of different-size objects
around MOST stars ... maybe ALL stars. Those objects are tremendously
difficult for us to see. We're just beginning to be able to see the most massive
planets that go with other stars, and already, something like a thousand of them
have been discovered. We know that they're there, but we can't see things like
their actual size or surface markings yet.
-- Stars are clumped in gatherings of several billion, called 'galaxies'.
Our sun is one of an estimated 300 to 400 billion stars in one galaxy,
which we call the "Milky Way Galaxy".
-- Astronomers estimate that there are billions of other galaxies.
So there are billions of billions of other stars, and most of them may
have several planets.
That's an awful lot of OTHER physical systems out there, that contain
other planets and moons.
Having trouble wrapping your mind around all of that ? Don't worry,
you're not the only one. It's easy for us to talk about it, but impossible
for our minds to actually understand it. It's just too big.
Answer:
The west and north of the country are dominated by sunken basins (such as the Gobi and the Taklamakan), rolling plateaus, and towering massifs. It contains part of the highest tableland on earth, the Tibetan Plateau, and has much lower agricultural potential and population.
Its territory includes mountains, high plateaus, sandy deserts, and dense forests. One-third of China's land area is made up of mountains. The tallest mountain on Earth, Mount Everest, sits on the border between China and Nepal. China has thousands of rivers.
Mountains, deserts, rivers, beaches, deep canyons and fertile plains all make up China's unique and storied geography.
The vast land expanses of China include plateaus, plains, basins, foothills, and mountains. Defining rugged plateaus, foothills and mountains as mountainous, they occupy nearly two-thirds of the land, higher in the West and lower in the East like a three-step ladder.
