Answer:
they're both cause by convection
Answer:
So as the mass of either object increases, the force of gravitational attraction between them also increases. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
Explanation:
Autotroph: a creature that obtains its carbon from inorganic carbon dioxide
Chemotroph: an organism that obtains energy from chemical substances-Heterotroph: an organism that must receive its carbon in an organic form
Phototroph: an organism that produces energy from sunlight
The term "primary nutritional groups" refers to a category of creatures that are separated into subcategories based on the sources of carbon and energy that they require for survival, growth, and reproduction. Carbon can come from organic or inorganic sources, and energy can be derived from either light or chemical molecules. ATP, carbs, or proteins are used to store the liberated energy as potential energy. The energy is eventually put to use for activities essential to life, like movement, growth, and reproduction.
