Metamorphosis
|
The process of an animal changing form during its life cycle.
|
|
|

|
A hard skeleton on the outside of the body of some animals.
|
|
|

|
A characteristic that increases an organism's ability to survive and reproduce in its environment.
|
|
|
Extinct species
|
A species that has no more of its kind alive.

|
Compare the way frogs breathe when they are tadpoles and the way frogs breathe when they are adults. Be sure to explain metamorphosis!
|
Tadpoles breathe through gills since they live underwater after hatching from its egg. An adult breathes through lungs since they live on land. Frogs go through metamorphosis. They go through three stages in their life cycle, egg, tadpole, and adult. When they’re tadpoles, they breathe through gills since they live underwater. When they're adults, they breathe through lungs since they live on land.

|
What are some structural adaptations of adult frogs that help them survive in their environment? Explain how each adaptation helps the frog.
|
Some structural adaptations that help adult frogs are long tongues that help them catch prey such as insects. They are able to grow lungs to help them adapt life on land.Small size and green color help them to blend into their environment. They are fast jumpers and have long legs to escape from predators. They also have webbed feet to help them swim. Frogs have many structural adaptations to help them survive.

|
What are the differences between complete and incomplete metamorphosis?
|
Complete metamorphosis has four stages of the animals life cycle, egg, larva, pupa, and adult. Incomplete metamorphosis is when animal goes through three stages in its life cycle, egg, nymph, and adult. In incomplete metamorphosis there are also less drastic structural changes.

|
|
Describe three adaptations that might help a plant survive in a very windy environment.
|
Three adaptations could be a strong stem and strong roots because that way the plant won't blow away. Thin needles so they won't blow away in effort to perform photosynthesis. And a flexible stem so the plant won't blow over.
|
|
|
What is the succession? How does succession occur over time?
|
Succession is a whole environment of plants adapting to change. It is a predictable order an environment goes through to adapt to a change over a long period of time. The change occurs because of the impact that established plants have on their own environment.
