Answer:
It would decrease
Explanation:
In an ecosystem, organisms feed on one another for survival due to the fact that energy needed for metabolic activities in individual organisms can only be obtained via food. This question depicts that certain bird population feeds on barley plant in an ecosystem.
However, If a disease attacks the plants in such a way that it destroys the barley plants in the field, this would cause the barley-eating bird population to DECREASE because their food source has been affected.
Chemical Property
<u>Explanation:</u>
When a substance is changed into another substance, may be due to addition of some other substance or removal of water from that substance.
* its identity changes
*its reactivity changes
*reactivity towards water, air and many other substances will change
*its chemical composition changes
and all these changes occurs due to the chemical properties.
If the physical property changes then there will be change in the state of matter, but its boiling point, melting point , reactivity towards water, air and other substances will not change, and it will not lose its identity.
Well one mole of stuff, any stuff, including carbon dioxide, specifies
6.022

individual items of that stuff.
Explanation:
And thus we work out the quotient:
7.2
