Concept:
Every organism requires a suitable place for:
• Shelter
• Food
• Reproduction
• Protection
The natural place where an organism lives is called its:
\[
\boxed{\text{Habitat}}
\]
Examples:
• Forest \( \rightarrow \) Tiger habitat
• Pond \( \rightarrow \) Frog habitat
• Desert \( \rightarrow \) Camel habitat
Step 1: Understand habitat.
Habitat provides:
• Suitable climate
• Water
• Food availability
Without proper habitat, organisms cannot survive properly.
Step 2: Differentiate related terms.
Environment:
• Overall surroundings
Niche:
• Functional role of organism
Trophic level:
• Feeding level in food chain
Habitat:
• Actual living place
Step 3: Analyze options carefully.
Option (A): Environment
General surroundings.
Incorrect.
Option (B): Niche
Role of organism.
Incorrect.
Option (C): Habitat
Place where animal lives.
Correct.
Option (D): Trophic level
Position in food chain.
Incorrect.
Step 4: Select the correct answer.
Therefore, the place where an animal lives is called:
\[
\boxed{\text{Habitat}}
\]
Hence,
\[
\boxed{(3)\ \text{Habitat}}
\]
