<u>Answer:</u>
Ecosystem is the level of organization which includes a community, population, and an individual.
<u>Explanation:</u>
- An ecosystem is the dynamic system of biotic and abiotic components that helps to maintain the circle of life.
- In an ecosystem there are different species and population of those species that exist together within a physical environment that is composed up of soil, water, minerals as well as weather conditions and climates.
- In ecosystem, there is the food chain as well as food web. The change in any component of the biotic or abiotic component would bring about change in every other component. Each component is interrelated with one another in an ecosystem.
The answer is B., Natural Selection.
Weather certainly doesn't change populations, and genes only caused individuals in a population to be slightly ( genetically-wise ) different from the others. It does cause change, but not change in the whole population over time.
Natural disasters don't change the populations over time either. Natural disasters only caused change in their environment, at most.
So, the only answer left is natural selection, and it makes sense too!
Natural selection is the process where the individuals with better traits suited to survive in that specific environment live on and give those good traits to their offspring.
The individuals with less suited traits to survive will die out, and will not be given an opportunity to reproduce and pass on their less suited traits, so over time, the population will increase of individuals with better suited traits to survive and the individuals with less suited traits will eventually die out, therefore making the entire population change.

2.a.The particles in the gas are moving faster than the particles in the liquid
2.b. The particles in a liquid are still connected, but the particles in a gas have separated from each other and now fly around to fill the container.
3.a. It dissolves into Hydrogen ions in water (H+).
The major difference between liquid and a gas particles of the same substance at the same temperature is that the particles in the gas are moving faster than the particles in the liquid due to distance between particles. The particles in a liquid are connected to each other, but the particles in a gas are separated from each other and moves freely in the container.
Acid forms Hydrogen ions in water (H+) and It cannot be mixed with oil due to its polarity. An acid is a molecule that donates a proton (H+) according to Bronsted–Lowry acid theory.

The pond will continue to get smaller and posibly will not exist at all. The area will be covered in shrubs because the dirt had softened because of the water. I think this might be the answer or something like it. Hope this helps!
