Animal Practice
Part I: Read the following paragraph about amphibians. Then answer the questions that follow.
Amphibians are vertebrates that include frogs, toads, newts and salamanders.
Amphibians have what is called a biophysical life cycle. The biophysical life cycle
means that amphibian larvae (eggs and tadpoles) live in water, but gradually
change (metamorphosis) to become better suited for the land. For instance, as
eggs and tadpoles they have gills and as an adult frog they have lungs.
The female amphibian can lay as many as 4,000 eggs. When the eggs
hatch, the tadpoles consume the soft egg jelly, called the egg sac.
After their egg sac is fully eaten, the developing tadpoles begin to eat drifting plant
matter and breathe through their gills at this stage. As they grow, their lungs develop, and they begin
making trips to the surface in order to breathe. Soon, they start to eat small invertebrates. From then on,
their diet becomes increasingly carnivorous, or meat-eating. As they continue to grow, they begin to
develop legs and their tails shrink.
Amphibians have smooth, moist, thin skin which is covered in mucus to retain water. Amphibians
are sometimes studied to determine the environmental health of an area. When pollutants are present,
amphibians are the first to be affected since their skin provides little protection. The widespread death of
amphibians in an area can indicate a high level of pollutants.
1. Would you classify amphibians as autotrophic or heterotrophic? Why?
2. What are the two structures that will help amphibians complete “Respiration” throughout their lifetime?
3. Amphibians perform external fertilization. Why do females need to lay so many eggs that undergo
external fertilization?
