Which statement is not correct?a)Water available for use is very limit...
The correct answer is D. "Animals living in the water are not harmed during floods" is not a correct statement. Here is a detailed explanation:
Water availability:
- A: "Water available for use is very limited" is a correct statement. Water scarcity is a global issue, and the availability of freshwater for use is indeed limited.
Water evaporation:
- B: "Water evaporates from plants, animals, and oceans" is a correct statement. Water evaporates from various sources like plants, animals, and the vast expanse of oceans. This evaporation is an essential part of the water cycle.
Vegetation during droughts:
- C: "There is no vegetation during droughts" is a correct statement. Droughts, characterized by prolonged periods of little to no rainfall, can lead to the drying up of water sources and adversely affect vegetation. Lack of water during droughts can cause plants to wither and die.
Effects of floods on aquatic animals:
- D: "Animals living in the water are not harmed during floods" is not a correct statement. Floods can have significant impacts on aquatic ecosystems and the animals living in them. The sudden increase in water levels, strong currents, and sedimentation can disrupt habitats, displace animals, and even lead to the loss of life.
In conclusion, statement D is the incorrect one as animals living in the water can be harmed during floods.

Understanding the Statements
The question presents four statements regarding water and its effects on the environment. Among these, option 'D' is deemed incorrect, and here's why.
Analysis of Option D
- Animals in Water During Floods
- Flooding can significantly disrupt aquatic ecosystems.
- Increased water levels can lead to habitat destruction, altering the environment where aquatic animals live.
- Rapid water flow can displace fish and other aquatic creatures, making it difficult for them to find shelter and food.
- Additionally, floods can introduce pollutants and debris into water bodies, which can harm aquatic life.
Why Other Statements Are Correct
- Statement A: Water Availability
- Water resources are limited, with only a small percentage of the Earth's water being fresh and accessible for human and ecological use.
- Statement B: Evaporation Process
- Water evaporates from various sources, including plants (transpiration), animals (respiration), and oceans, contributing to the water cycle.
- Statement C: Vegetation During Droughts
- Vegetation typically suffers or may die during droughts due to lack of water, leading to a stark landscape with minimal plant life.
Conclusion
In conclusion, while flooding is often perceived as a water abundance issue, it can have detrimental effects on aquatic animals and their habitats, making option 'D' the incorrect statement. Understanding these impacts is crucial for appreciating the delicate balance of ecosystems and the importance of water management.
