*URGENT*<br> Why do we think of ecosystems as systems within systems?

Alexandra [31]

Answer:

An ecosystem is not just a collection of species, but includes living things interacting with each other and their nonliving environment. In the systems view, the "objects" of study are networks of relationships.

Juan and his science class are constructing models of sugar crystals. He wants his model to show how the sugar molecules move in

inna [77]

Answer:

The correct answer is option B. "Fill a clear cube with them".

Explanation:

Sugar crystals, colloquially known as "rock candy", are conglomerates of sugar molecules that are formed when sugar-saturated water are cooled. Sugar crystals are arranged in a three dimensional repeating pattern, forming a cube like structure. Therefore, Juan could fill a clear cube with its plastic foam balls to represent sugar crystals. I attached an image of sugar crystals dissolving in water as reference.
