STAAR Biology Review TEKS 12.B-E

The Indian Leaf butterfly has traits that allows it to resemble a leaf. The bright colors of the monarch butterfly indicate that the butterfly tastes bad or could be poisonous.

How does the appearance of these butterflies help them survive?

• The Indian Leaf butterfly is able to avoid predators while the monarch butterfly warns predators away.

• The Indian Leaf butterfly frightens predators away while the monarch butterfly poisons predators before they can eat it.

• Both butterflies rely on camouflage to avoid predation.

• Both butterflies cooperate with one another to avoid predation.

• Organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels

• Organisms at higher trophic levels require smaller habitats than organisms at lower trophic levels

• Organisms at lower trophic levels provide less energy than organisms at higher trophic levels

• Organisms at lower trophic levels outcompete organisms at higher trophic levels

A student is asked to draw a food web in which the same organism is a primary consumer as well as a secondary consumer. How should the organism be represented in the food web?

• The organism must have an arrow pointing form it to a tertiary consumer and another arrow pointing from it to a decomposer.

• The organism must have an arrow pointing from it to a secondary consumer and another arrow pointing to it from the top predator.

• The organism must have a n arrow pointing to it from a producer and another arrow pointing to it from a primary consumer.

• The organism must have an arrow pointing from it to a primary consumer and another arrow pointing away from it to a decomposer.

• Less atmospheric carbon dioxide would be available to phytoplankton.

• Dissolved carbon dioxide gas in the ocean would increase because surface winds would cause a deeper circulation pattern, making more room for the gas

• Less carbon dioxide gas would be contained in the ocean because increasing precipitation would dilute the carbon entering the ocean

• Less carbon dioxide would be dissolved in the ocean because increasing atmospheric temperature would cause ocean temperatures to increase.
