Answer:
The aquarium is covered and not in sunlight
Diminishing
Explanation:
The sun is the ultimate source of energy for all life and activities on earth. The aquarium is no exception.
Green plants manufactures food in the process of photosynthesis by combining carbon dioxide and water in the presence of sunlight.
- This food provides all other lives with energy through the break down of energy held in carbon chains.
Is the aquarium now in sunlight or is it covered?
Here is a feeding relationship between plants and fish in a pond. The producer here is the plants. The consumer is the fish.
Using carbon dioxide and water, plants manufactures food. When the amount of carbon starts decreasing it shows that the aquarium is covered.
The source of dissolved carbon dioxide in water is the fish which gives off this gas as it respires. When the fish ceases to respire, it does not have enough food and might have died thereby decreasing carbon dioxide levels.
What is happening to the number of energy storage molecules in the plants and fish as a result?
The energy levels in both plant and fish will begin to reduce because the plant is unable to produce food which the fish depends on.
This will furnish a rapid decline in the energy available in these living organisms since the plants are not able to produce.
Answer:
What can liquids do that solids cannot?Liquids will flow and fill up any shape of container. Solids like to hold their shape. In the same way that a large solid holds its shape, the atoms inside of a solid are not allowed to move around too much. Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want.
What can gases do that solids cannot?The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

Answer:
The density of the metal is 0.561 g/mL
Explanation:
The computation of the density of the metal is shown below;
As we know that
The Density of the metal is
where,
Mass = 4.9g
Change in volume = 6.9 mL
Now place these values to the above formula
So, the density of the metal is
= 0.561 g/mL
Hence, the density of the metal is 0.561 g/mL
We simply applied the above formula so that the correct density could arrive
