what are the biotic and abiotic factors affecting the freshwater crocodile?

The Correct Answer and Explanation is :

Biotic and Abiotic Factors Affecting the Freshwater Crocodile

Biotic Factors (Living Components)

1. Prey Availability – Freshwater crocodiles feed on fish, amphibians, crustaceans, and small mammals. The abundance of prey directly affects their survival and population density.
2. Predators & Competitors – While adult freshwater crocodiles have few natural predators, juveniles are vulnerable to birds of prey, larger crocodiles, and mammals such as wild boars. They also compete with saltwater crocodiles in overlapping habitats.
3. Human Interaction – Hunting, habitat destruction, and pollution caused by human activities impact their survival. In some regions, they are hunted for their skin and meat.
4. Parasites & Diseases – Bacteria, fungi, and parasitic worms can weaken crocodiles, reducing their lifespan and reproductive success.
5. Vegetation & Nesting Sites – Plants along riverbanks provide essential nesting sites and shelter. Loss of vegetation due to deforestation or erosion can disrupt breeding.

Abiotic Factors (Non-Living Components)

1. Water Quality – Clean, oxygen-rich water is essential for freshwater crocodiles. Pollution from agricultural runoff and industrial waste can harm them.
2. Temperature – Being ectothermic (cold-blooded), freshwater crocodiles rely on external temperatures to regulate their body heat. Climate change and temperature fluctuations affect their metabolism and reproductive cycles.
3. Salinity Levels – Unlike saltwater crocodiles, freshwater crocodiles prefer low-salinity environments. Changes in water salinity due to droughts or human activity can force them to migrate.
4. Rainfall & Seasonal Changes – Water levels in rivers and lakes fluctuate with seasonal rainfall. Droughts or flooding can impact their habitat, availability of prey, and nesting success.
5. Substrate & Riverbank Stability – The composition of riverbanks affects nesting success. Erosion or land degradation can lead to a loss of nesting areas, reducing reproductive success.

These biotic and abiotic factors collectively shape the survival, distribution, and behavior of freshwater crocodiles in their natural habitats.
