Answer:
A source from which organisms generally take elements is called exchange pool (option B).
Explanation:
Options for this question are:
- <em>Food web.</em>
- <em>Exchange pool.</em>
- <em>Reservoir.</em>
- <em>Biotic community.</em>
The term exchange pool is related to the biogeochemical cycles that exist in nature, referring to the source from which elements present in the environment become part of living organisms.
<u>Exchange pools are the biotic components</u> -like animals and plants- of an ecosystem, which determine the passage of elements between living beings. An element can remain as a reservoir (abiotic) in the soil, and then be incorporated into the exchange pool.

Answer:
Q1) True
Q2) Metabolism
Q3) Physiological response
Explanation:
Q1) Energy cannot be created (first law of thermodynamics). Life needs an energy source to transform. Without the energy from the sun or any other sources, life would cease to exist. (True)
Q2) An organism chemical reactions consist, in general, breaking down complex molecules (catabolism) releasing energy or to form complex structures from simpler molecules (anabolism) which require energy . The total of this reactions is called metabolism.
Q3) Hibernation is physiological state of inactivity and metabolic depression in some organisms, which result as a response to low temperatures and unavailability of food.

2. Deceleration of impulse
