There are five animals $P$, $Q$, $R$, $S$ and $T$. The animal $P$ always lives in water and has gills for breathing. The animal $Q$ can stay in water as well as on land and can breathe through both, moist skin and lungs. The animal $R$ lives in soil and breathes only through its skin. The animal $S$ lives on land and breathes through spiracles and tracheae. The animal $T$ lives in water and breathes through its cell membrane. Identify the animals:
$(a)$ Which of the animals could be $Amoeba$?
$(b)$ Which of the animals could be frog?
$(c)$ Which animal could be fish?
$(d)$ Which animal could be grasshopper?
$(e)$ Which animal could be earthworm?
$(a)$ Which of the animals could be $Amoeba$?
$(b)$ Which of the animals could be frog?
$(c)$ Which animal could be fish?
$(d)$ Which animal could be grasshopper?
$(e)$ Which animal could be earthworm?
(N/A) Step $1$: Analyze the respiratory characteristics of each animal.
Step $2$: $P$ lives in water and uses gills, which is characteristic of fish.
Step $3$: $Q$ lives in water and on land, using moist skin and lungs, which is characteristic of a frog.
Step $4$: $R$ lives in soil and breathes through its skin, which is characteristic of an earthworm.
Step $5$: $S$ lives on land and uses spiracles and tracheae, which is characteristic of a grasshopper.
Step $6$: $T$ lives in water and breathes through its cell membrane, which is characteristic of $Amoeba$.
Conclusion: $(a)$ $T$, $(b)$ $Q$, $(c)$ $P$, $(d)$ $S$, $(e)$ $R$.
Step $2$: $P$ lives in water and uses gills, which is characteristic of fish.
Step $3$: $Q$ lives in water and on land, using moist skin and lungs, which is characteristic of a frog.
Step $4$: $R$ lives in soil and breathes through its skin, which is characteristic of an earthworm.
Step $5$: $S$ lives on land and uses spiracles and tracheae, which is characteristic of a grasshopper.
Step $6$: $T$ lives in water and breathes through its cell membrane, which is characteristic of $Amoeba$.
Conclusion: $(a)$ $T$, $(b)$ $Q$, $(c)$ $P$, $(d)$ $S$, $(e)$ $R$.
