Explain how changes in land use can impact an ecosystem. Reducing the amount of land available will reduce the amount of available resources. This leads to a loss of species because they can no longer survive. This will decrease populations which will have a permanent effect on the ecosystem.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

some scientists like gregory adcock agree with thorne's theory of regional continuity.
