Answer:
Air
Explanation:
depending on the concentration of Oxygen in any of the medium- air or water, Oxygen pick up will be easier in air than water. This is because the energy barrier for the exchange of gases is higher in a liquid medium than in a gaseous medium.
Answer:
The sample a which is solid at 20°C is "Iodine"
The sample b which is liquid at 20°C is "Bromine"
The sample c which is gas at 20°C is "Chlorine"
Explanation:
Iodine : It starts melting at 113.7°C, so the solid sample found is the iodine. Iodine is present in both solid as well as in vapor state. Basically it is kept in closed jars. Only when it reaches the temperature above the melting point is starts melting.
Bromine: It is a non metallic element that is present in the liquid state, being a member of halogen group. It is heavy, mobile and dangerous reddish brown liquid. It is corrosive in nature, when comes in contact with human tissue and causes irritation in eye when comes in contact with its vapor.
Chlorine: In room temperature it is gas, as it has weak intermolecular interaction which fails to keep the molecules closely attached.
Answer: The correct terms for completing the concept of energy and trophic levels are as follows-
a) Solar energy
b) Trophic levels
c) Heat
d) Tertiary consumers
e) Secondary consumers
f) Primary consumers
g) Primary producers
h) Decomposers.
Energy flow in an ecosystem is driven by solar energy that is captured and converted into chemical energy by primary producers ( like green plants and algae). The energy moves through different trophic levels according to the 10% law of energy transfer and the rest energy is released as heat.
Primary producers are eaten by primary consumers, which are eaten by secondary consumers that are eaten by tertiary consumers. The organic matter that becomes dead is ultimately decomposed with the help of decomposers.
