4 is correct. In a wide expanse of space, gravity drew dust and gas together to create the solar system. The sun formed first from the vast material.
Answer:
Due to the earth's rotation and the gravitational pull of the moon.
Answer:
The scale is same.
Explanation:
The scale of nuclear fusion reaction on earth is the same as compared to fusion reactions that is happening in the sun because both reactions produces the same product i. e. energy and heat etc and both are occurring naturally. Due to large size of the sun, huge number of nuclear fusion reactions occur ac compared to the earth which is smaller in size so the scale of both nuclear fusion reactions are the same but vary in numbers.
The plates will move and the underwater island will start to move and shift. It's possible it will also weather
Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
