Match each organism with its characteristic anatomical structure or cellular mechanism used in nutrition and digestion.
- AmoebaPseudopodia used for phagocytosis to form intracellular food vacuoles
- CockroachChitinous teeth inside the proventriculus/gizzard used to churn solid food
- Domestic Fowl (Bird)Muscular gizzard containing swallowed stones/grit for mechanical grinding of seeds
- RabbitEnlarged caecum hosting symbiotic microorganisms for hindgut cellulose fermentation
Answer
Amoeba matches with pseudopodia for intracellular ingestion; Cockroach matches with chitinous teeth in the proventriculus for crushing food; Domestic Fowl matches with a muscular gizzard containing grit for grinding seeds; Rabbit matches with an enlarged caecum for microbial cellulose fermentation.
Each animal demonstrates structural adaptations tailored to its mode of feeding: Amoeba utilizes pseudopodia for phagocytosis; insects like cockroaches use chitinous teeth in the proventriculus to crush solid particles; birds utilize a muscular gizzard with ingested grit to grind grains; and non-ruminant herbivores like rabbits depend on an enlarged caecum containing symbiotic microbes to break down plant cellulose.
