Answer:

15%

Explanation:

From the question given above, the following data were obtained:

Mass of sugar = 15 g

Mass of water = 85 g

Percentage of sugar in the solution =?

Next, we shall determine the mass of the solution. This can be obtained as follow:

Mass of solute (sugar) = 15 g

Mass of solvent (water) = 85 g

Mass of solution =?

Mass of solution = mass of solute + mass of solvent

Mass of solution = 15 + 85

Mass of solution = 100 g

Finally, we shall determine the percentage of the sugar in the solution. This can be obtained as follow:

Mass of solute (sugar) = 15 g

Mass of solution = 100 g

Percentage of sugar in the solution =?

Percentage = solute /solution × 100

Percentage = 15 / 100 × 100

Percentage of sugar in the solution = 15%

Based on ecological studies, the definitions below applies to the given terms:

Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

<h3>What is ecology and what are some terms in ecology?</h3>

Ecology is the study of living things and their interactions with their environment.

Some terms in ecology include:

Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available
