The maximum size of a population that a given area can support is known as

Step 1: Analyze the question The question asks for the term describing the maximum population size that an environment can sustain (support) over time.

Step 2: Explain the concept Every habitat has limited resources such as food, water, shelter, and space. Because of this, a population cannot keep growing forever. The largest number of individuals of a species that the environment can support indefinitely, without being degraded, is called its carrying capacity.

Step 3: Check each option

• A. Population density: This is the number of individuals per unit area (for example, 50 goats per km²). It describes how crowded a place is, not the maximum the area can support. ❌
• B. Carrying capacity: This is the maximum population size that an environment can support given its available resources. ✅
• C. Population growth: This is the change in the number of individuals over time (increase or decrease). It is not a maximum limit. ❌
• D. Maximum population: This is not a standard ecological term. It sounds like the definition but is not the correct scientific name. ❌

Step 4: Answer The correct answer is **B.

Tip: Think of a bus. Its carrying capacity is the number of passengers it can carry safely. In the same way, an environment has a limit to the number of organisms it can support. In a population growth graph (S-shaped curve), carrying capacity is the level at which the curve flattens out.
