▶️ Answer/Explanation
By observing the flow of the diagram, we can identify the specific biological functions occurring at each label:
1. Identification of Arrow $P$ (Nutrition):
This arrow represents the intake of energy and materials. We see $P$ moving from the atmosphere into the plant (photosynthesis) and from the plant into the chicken (feeding). Both are forms of nutrition.
2. Identification of Arrow $Q$ (Excretion):
This arrow tracks the removal of substances from the organisms. It leads directly to “waste products” and shows the release of $CO_2$ from the chicken. The removal of metabolic waste is the definition of excretion.
Summary:
Since $P$ involves taking in nutrients and $Q$ involves getting rid of waste, option B is the only logical choice.
▶️ Answer/Explanation
The correct answer is C.
The organism shown is an ant ($\textit{Formica fusca}$), which belongs to the class Insecta. The defining characteristic that distinguishes insects from other arthropod groups is the presence of three pairs of legs (a total of $6$ legs).
▶️ Answer/Explanation
Correct Answer: B
Carbohydrates (such as glucose and starch) are produced during the process of photosynthesis. This process takes place within specialized organelles called chloroplasts found in the cells of green leaves.
