Heterotrophs are those organisms that cannot prepare their food from nature 

Hence depend on other organisms that produce food (autotrophs).

Non-green plants cannot make their food due to the absence of chlorophyll in their leaves

Explanation

The spleen is often referred to as the "graveyard of RBCs"

Because it is responsible for filtering and breaking down old, damaged, and worn-out red blood cells (RBCs).

Explanation

• Carbon monoxide (CO) binds strongly with hemoglobin in the blood.
• It forms carboxyhemoglobin (COHb), reducing the blood's oxygen-carrying capacity.
• CO binds to hemoglobin about 200–250 times more strongly than oxygen.
• This can lead to oxygen deficiency (hypoxia) in body tissues.
• Carbon monoxide is a colorless, odorless, and poisonous gas.
