Desert organisms show adaptations like nocturnal behavior to avoid heat, and physiological mechanisms to conserve water.
Intrinsic rate of increase (biotic potential) is expressed as λ and represents maximum reproductive capacity under ideal conditions.
Primary succession occurs on bare, lifeless substrates where no soil exists, such as newly formed volcanic islands.
Decomposer bacteria have generation times measured in hours to days, making them have the shortest lifespan compared to other organisms in the ecosystem.
Western Ghats and Northeast India are recognized global biodiversity hotspots with high endemism and species richness.
Desert animals like jerboas exhibit nocturnal behavior and have efficient kidneys to conserve water, reducing evaporative loss.
CFCs (chlorofluorocarbons) release chlorine atoms that catalytically destroy ozone molecules in the stratosphere.
Tapeworm derives nutrition from host while causing harm, exemplifying parasitism.
Increased herbivore population leads to higher consumption of plant material, resulting in decreased plant biomass.
Nitrogen fixation is the process where atmospheric N₂ is converted to ammonia by nitrogen-fixing bacteria, making it available to organisms.
