How does knowing the equivalence point for a titration help pick out an indicator?

Answer is: near equivalence point indicator should change color, so we must pick indicator who changes color near pH of equivalence point.
Equivalence point is the point which there is stoichiometrically equivalent amounts of acid and base. 
Chemist can draw pH curve (graph showing the change in pH of a solution, which is being titrated) for titration and determine equivalence point.

Explain the difference between ecosystem, community, and population.

Studentka2010 [4]

Out of the three you gave ecosystem is what I would call the most broad. An ecosystem includes living AND non-living things in an area

Community is all the LIVING things in an area (plants are included and I think bacteria is too, but I'm not sure)

Population is pretty narrow it just looks at specific species in one area. Population of mosquitoes doesn't include butterflies, if only looks at mosquitoes
