Understanding Ecosystems
An ecosystem is a complex network of living organisms and their physical environment. To determine which statements are correct, let’s analyze them one by one.
Statement 1: It comprises of biome only
- This statement is incorrect.
- A biome is a large ecological area on Earth’s surface, but an ecosystem includes various components beyond just biomes.
Statement 2: It comprises of biome and habitat
- This statement is correct.
- An ecosystem encompasses both biomes (large-scale ecological areas) and habitats (specific environments where organisms live).
Statement 3: It is an open system
- This statement is correct.
- Ecosystems are typically open systems as they exchange matter and energy with their surroundings. For instance, they receive sunlight, nutrients, and gases from the environment.
Statement 4: It is a closed system
- This statement is incorrect.
- Ecosystems are generally not closed systems because they interact with external factors, such as climate and human influence.
Correct Answer Explanation
Given the analysis:
- The correct statements are 2 and 3.
- Therefore, the correct answer is option B (2, 3).
In summary, ecosystems include both biomes and habitats, and they operate as open systems due to their interactions with surrounding environments. Understanding these concepts is crucial for studying ecology and environmental science, especially in the context of UPSC examinations.
