The specific portion of a habitat which is occupied by a particular species is referred to as

Step 1: Analyze the question The question asks for the term describing the specific portion of a habitat occupied by a particular species. The key ideas are "specific portion" and "particular species."

Step 2: Explain the concepts

• Habitat: The place where an organism lives (e.g., a pond, a forest).
• Ecological niche: The specific role and position a species has within its habitat. This covers where it lives, what it eats, and how it interacts with other organisms. It is the species' "address and occupation" combined.
• Population: A group of individuals of the same species living in the same area.
• Biotic community: All the living organisms (plants, animals, microbes) living together in a habitat.
• Ecosystem: The community of living things together with their non-living environment, interacting as a unit.

Step 3: Work through the options

• A. Ecological population: This refers to the number of individuals of one species in an area, not the portion of habitat they occupy. ❌
• B. Ecological niche: This is the specific part of a habitat occupied by a particular species, along with its role there. ✅
• C. Biotic community: This covers all the living species together, not one particular species. ❌
• D. Ecosystem: This is the whole interacting system of living and non-living things, which is far too broad. ❌

Step 4: Answer The correct option is B. Ecological niche.

Exam tip 💡 Remember: Habitat = address, Niche = job (and exact spot). For example, in a pond (habitat), a tadpole's niche is the shallow water where it feeds on algae. If a question mentions a "particular species" and its specific position or role, think niche.
