Warm water acts as a barrier disrupting fish migration patterns and it is also harmful to fish because of lower oxygen concentration of water.
<u>Explanation</u>:
- Releasing warm water into lakes or rivers is equivalent to thermal pollution. It is very harmful for not only fish, but all living organisms that make use of water.
- When water becomes more and more warm, it disrupts the migration patterns of fish. They will be forced to move to different places which have cooler water.
- The most harmful thing about warm water for fish is that it lowers the oxygen concentration in water. When water becomes warm, fish get more active and this requires them to get more energy and more oxygen. But the major problem with warm water is that it carries less dissolved oxygen than cool water. This is malevolent to fish.
The following are the expected ranks of biomes based on increased oxygen for plant growth and they are
1. Desert,
2. Grassland
3. Temperate Forest
4. Tropical Rain Forest
The desert biome is formed owing to very limited annual rainfall and it covers approximately 20% of the Earth. The Grassland is predominantly dominated by grasses while the temperature in the temperate forest is around 10 degree celcius. The plants and trees in this biomes develop special adaptations for their survival. However, the rain forest is characterized with all year round rain hence the biome is moist. The biome is known for vegetations with dense canopies.

Answer:
The differences in characteristics between individuals of the same species is called variation . Some variation is passed on from parents to offspring, via genes during reproduction. ... Some variation is the result of differences in the surroundings, or what an individual does. This is called environmental variation.
