Frog Biology and Ecology Quiz

General Characteristics

• Frogs are amphibians, meaning they live part of their lives in water and part on land.
• They are ectothermic, meaning their body temperature depends on the environment.
• Frogs have smooth, moist skin, typically a variety of colours for camouflage.
• They have strong, webbed feet ideal for swimming.
• Most have long, sticky tongues for catching prey.
• Frogs exhibit remarkable diversity in size, shape and colour, with thousands of species worldwide.

Reproduction

• Frogs typically breed in water.
• Many species exhibit external fertilization, where eggs and sperm are released into the water.
• Tadpoles hatch from eggs and undergo metamorphosis, transforming from aquatic larvae to land-dwelling adults.
• Some frog species show parental care, protecting their eggs and developing offspring.

Diet

• Adult frogs are carnivorous, feeding mainly on insects, worms, and other small invertebrates.
• Their long, sticky tongues are crucial for capturing prey.
• Some species also consume small fish, crustaceans, and spiders.
• Tadpoles are herbivores, feeding on algae and other aquatic plants.

Life Cycle

• Eggs are laid in water, often in ponds, lakes, or streams.
• The eggs hatch into tadpoles, which are aquatic larvae.
• Tadpoles grow and develop into froglets, with legs and lungs emerging.
• Froglets eventually transform into fully formed adult frogs.

Metamorphosis

• Metamorphosis is a fundamental part of a frog's life cycle.
• This change is complete when the larva (tadpole) morphs into an adult frog.
• Tadpoles are initially filter-feeding herbivores but gradually develop jaws and teeth adapted for consuming various prey items.
• The characteristic development of lungs occurs during metamorphosis.
• The dramatic change in appearance and diet is due to hormonal and physiological changes.

Habitat

• Frogs inhabit diverse habitats across the globe, from tropical rainforests to deserts.
• They are often found near water sources, but some species can survive in drier environments.
• The type of habitat plays a considerable role in frog species selection and distribution.

Threats to Frogs

• Habitat loss and fragmentation due to human activities.
• Pollution in water sources, directly affecting frog populations.
• Climate change is creating unpredictable and stressful conditions.
• Impacts from increased UV radiation, leading to adverse effects.
• Introduction of invasive species, competing for resources and causing disease.
• Diseases, both fungal and viral, which might wipe out entire populations.
• Overexploitation, for human consumption and other purposes.

Conservation Efforts

• Protect and restore wetlands and other aquatic habitats.
• Reduce pesticide use in agricultural areas and other land.
• Control the spread of invasive species.
• Monitoring populations and studying the causes of decline.
• Researching disease outbreaks and implementing preventative measures.
• Raising awareness about frog conservation and the importance of amphibians.

Importance of Frogs

• Frogs play a crucial role in maintaining ecosystem health.
• They contribute to biological control of insect populations, controlling pest numbers naturally.
• Serve as an important source of food for other species, maintaining a balanced food chain.
• Their presence signifies healthy ecosystems around the world.

Classification

• Frogs belong to the order Anura within the class Amphibia.
