Sulfur dioxide (SO₂) combines with water vapor to form sulfuric acid, which falls as acid rain, causing environmental damage.
The Western Ghats are designated as a hotspot due to exceptional plant and animal endemism, with thousands of species found nowhere else on Earth.
Nutrient overloading from agricultural runoff causes algal blooms and oxygen depletion, directly causing eutrophication.
Predator populations increase after prey abundance increases, creating characteristic cyclic patterns with a temporal delay between the two population peaks.
Both the fungus and plant benefit: fungi gain carbohydrates while helping the plant absorb water and minerals, making it a mutualistic relationship.
The Thar Desert and other Indian desert regions exhibit high temperatures, minimal rainfall, and adapted vegetation like acacia and desert grasses.
Secondary succession occurs on previously colonized areas where soil remains intact, such as after a fire. Primary succession occurs on bare rock or new land.
Disease spread increases with population density, making it a density-dependent factor. Natural disasters are density-independent factors.
The 10% law indicates that only about 10% of energy available at one trophic level is transferred to the next level, with the rest lost as heat and through metabolic processes.
Phytoplankton are autotrophic organisms that produce their own food through photosynthesis, making them primary producers in aquatic ecosystems.
