Answer:
The force that pulls the moon toward Earth is called _Gravity_.
Explanation:
Gravity is the force that holds the planets in orbit around the sun and keeps the moon to orbit around Earth. the moon pulls the oceans towards it causing ocean tides, because of the gravitational pull. gravity creates planets and stars by pulling material together from which stars and planets are made.
In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are the amount of water and temperatures. Terrestrial ecosystems rely on the sun's energy to support the growth and metabolism of the organisms. Plants use the sunlight, then they supply the organisms that are higher up the food chain with energy and the structural buildings blocks of life. Water is also essential for the survival of these organisms.
I'd say option 4, because all of those are capable of changing the enviroment
