In ecology, a group of particular organisms which live in a community is called POPULATION.
For instance, all the number of lions which live in a community make up the population of lions in that community. Populations of different species of animals that are found in that area combine together to form the community.
The untreated human waste may never be dumped in inland waters. This is because it is illegal and may also affect the creature that live in the waters. The untreated human waste must be stored in a reservoir in the ship and later disposed in appropriate sewages that are on land.
Species are single organisms that are able to reproduce, while a population is a group of species living in the same general area.
<span>The variables in this study would be the folic acid used (the independent variable) and the DNA formed through the implementation (the dependent variable). By changing the amount of folic acid used in the experiment, the DNA will possibly be changed in the microbes.</span>
