The first stage of a frog's life cycle and a butterfly's life cycle is the egg. Both frogs and butterflies start their life cycle as eggs, which hatch into larvae or caterpillars respectively. This stage is crucial for their development and growth before they undergo metamorphosis into their adult forms.

This picture is an example of a life cycle because it depicts the different stages of a living organism's development and growth. A life cycle typically includes birth or hatching, growth, reproduction, and eventually death. The picture may show the various stages of an animal or plant's life, highlighting the changes and transformations that occur throughout its lifespan.

Animals who are extinct no longer exist. Dinosaurs are extinct because they no longer are alive.

A vertebrate is any animal with a backbone.

A fossil is a hardened mineral, bone, or material left from the past.

Fossils of ancient plants and animals show changes over time. Animals existing today were not here in the past.

Animals all have different life cycles, some may be similar, but they are all different.

When birds fly south for the winter, this is called migration.

When an animal hibernates they sleep for long periods of time and their heart rate and other body systems slow down to save energy.

When some animals are born they already know how to find food, other need to be taught. The ones who are born knowing what to do are born with instincts.

When tree sap hardens we call this amber. Some amber has been maintained for hundreds of years preserving the fossils of ancient bugs and small animals.

The hard covering is called a chrysalis. We sometimes refer to this as the cocoon.

The life cycle of a frog begins with an egg, which then hatches into a tadpole. The tadpole goes through metamorphosis and develops legs, becoming a tadpole with legs. After further development, it transforms into a froglet. Finally, the froglet matures into an adult frog.

We inherit traits from our parents, such as eye color, hair color and other things.

Animals adapt to their environment in order to survive. They may need to adapt because of changes in food, weather, or other things.

Traits can be any characteristic such as height, eye color, hair color, and more.

The stages of a butterfly's life cycle are: egg, larva, pupa, adult

When a harmless animal looks like a poisonous one it is called mimicry.

Animals migrate for various reasons. Some migrate to move to warmer climates during winter seasons, as they are unable to survive in cold temperatures. Others migrate in search of more available food, as certain areas may become scarce in resources. Lastly, migration is often driven by instinct, as animals have an innate behavior to move from one place to another in order to survive and reproduce. Therefore, all of the given options are valid reasons for animal migration.
