What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

As the amount of salt in water increases, the___________ of the water increases.
1. temperature
2. humidity
3. density
4. size
Answer:
3
Explanation:
As the amount of salt in water increases, the density of the salt water increases. The more the particles of the in water being added to the total mass and thus increases the density.
What is density ?Density of a substance is the measure of its mass by volume. It describes how closely packed its particles are. The density of a substance depends on the bond type, pressure and temperature.
The density of pure water is 1 g/ml. However, when salt is added to water it becomes denser since the mass of the solution changes from that of water.
Hence, more the salinity of the salt solution, more denser it is. Because, amount of salt is contributing to the total mass. Therefore, As the amount of salt in water increases, the density of the salt water increases.
