Which animal has a body structure that will BEST protect it from an attack by a predator?

• deer

• worm

• turtle

• flamingo

What function do all these bird beaks have in common that help these birds survive in a lake environment?

• capturing prey from water

• defending breeding territroy

• fighting predators in the lake

• attracting mates from a distance

Observe the behavior shown.

This behavior has an important similarity to a spider spinning
a web. Both come naturally when born. What are behaviors like
these called?

• physical traits

• social behavior

• learned behavior

• instinctual behavior

Animals have instincts and learned behaviors that help maintain a stable population in an ecosystem. Which statements describe behaviors that are MOST LIKELY to increase the chance for the animal to survive in its environment? Circle the letters of TWO correct answers.

• Ostriches lay large eggs.

• Tree frogs have loud chirps

• Coral snakes have bright colors

• Sandhill cranes live in groups of four or more

• Sea turtles move to the ocean as soon as they are hatched

Paula, a field scientist, uses binoculars to study a herd of wildebeests from a safe distance. They are all eating short, thick grass. She observes one young wildebeest walk far away from the other animals.

Learned behaviors can increase an animal’s chance of survival. The young wildebeest must learn how to survive in the African plains. Which behavior functions to help the young wildebeest survive the BEST in its environment?

• fighting with other wildebeests

• being able to eat grass alone

• staying near other wildebeests

• getting chased by predators

Part A. Learned behaviors can increase an animal’s chance of survival. The young wildebeest must learn how to survive in the African plains. Which behavior functions to help the young wildebeest survive the BEST in its environment? (staying near other wildebeests)

Which statement BEST supports the answer to Part A?

• The young wildebeest can run extremely fast

• Fighting with other wildebeests helps them to get more grass to eat.

• The young wildebeest is more likely to be caught by predators when it is separate from the herd

• There will be less grass to eat when the young wildebeest is with the rest of the herd.

Butterflies have very long, tubelike tongues. Hummingbirds have very long tongues.

Which statement best describes why butterflies and hummingbirds both have long tongues?

• Butterflies and hummingbirds both migrate

• Butterflies and hummingbirds are both attracted to brightly colored flowers.

• Butterflies and hummingbirds eat the same food.

• Butterflies and hummingbirds have the same predators

The tallest trees in a rainforest are removed for lumber.  This increases the amount of light on the forest floor.  The table shows information about fungi and ferns that grow on the forest floor.

Which statement explains why one organism is better adapted to the removal of the tall trees?

• The fungi are better adapted because they have spores that grow better in the dark.

• The ferns are better adapted because they have strong root systems.

• The fungi are better adapted because they can get energy from decaying trees.

• The ferns are better adapted because they get energy from the sun.

The raccoon can be found in most areas of Texas.  The coati has a smaller territory and is found from Big Ben to Brownsville.  These two species are related.  The chart shows the characteristics of these two species.

Which statement does NOT describe how the body structures of these animals help them escape predators?

• Paws with long claws on flexible toes to help them climb trees.

• Sharp teeth allow them to catch prey on land or in water.

• Long tails allow them to balance on branches in trees.

• Good eyesight helps them to see at night.
