Answer:
The given statement about the air parcel is True
Explanation:
It can be explained as atmospheric pressure on air parcel is higher due to which it contracts when it is close to earth but if the temperature inside the parcel is more than that of the surrounding then due to low density it will rise upward and as the parcel gains height the air pressure exerted by the surrounding on the parcel reduces due to increase in height of the parcel from the earth and hence the air parcel expands. The entire process happens with heat being constant (adiabatic) i.e., amount of heat transferred in the expansion remains same.
Now, the same amount of heat is scattered on the expanded area leading the parcel to cool as it ascends.
Biotic factors are organisms that interact with non-living & living parts of an ecosystem.
Egs. badgers, worms, fungi, bacteria, insects.
