Answer:
Decomposers recycle essential nutrients back into an ecosystem
Explanation:
An ecosystem works thanks to the constant transformation of energy. The role of the decomposers will be to transform energy into something useful in the ecosystem. For example, The bacteria which will rotten the apples that fall from a tree onto the ground are recycling or making available this energy for other organisms to use it. As part of this example, the essential nutrients of the apples will be available to be reabsorved by the roots of the apple tree thanks to the transformation of energy done by the bacteria in the apples.
<u>Answer:</u>
<em>Warm water </em><u><em>is less dense than cold water and has lower salinity than cold water.
</em></u>
<u>Explanation:</u>
When the <em>temperature of water increases</em> the freedom movement of molecules increases and they expand. Hence the space between the molecules increases thereby causing the liquid to occupy more volume. Density is <em>the ratio of mass and volume</em> which means an increase in volume will decrease the density of a liquid.
Thus an increase in temperature has a negative impact on density and the density decreases. Salinity tends to increase with density. Thus temperature has a negative impact on salinity as well. When <em>temperature increases salinity decreases.
