In a food chain, energy does not flow directly from –

• consumer to producer

• consumer to decomposer

• producer to decomposer

In a desert food chain, wild pigs eat cacti. Then, coyotes eat wild pigs. When the coyote dies, its body begins to decay and the nutrients are returned to the soil. How does energy move in this food chain?

• from producers to consumers to decomposers

• from consumers to producers to decomposers

• from decomposers to consumers to producers

• from decomposers to producers to carnivores

Plants grow from seeds. Sometimes the seeds are carried far away from the parent plant. Both of these seeds have structures that –

• allow them to be dispersed by sunlight

• allow them to be dispersed by wind

• allow them to be dispersed by water

• allow them to be dispersed by animals

The owl butterfly and swallowtail caterpillar have patterns on their body that look like large eyes. How does this adaptation help them survive?

• the color of a plant’s flower

• the number of insects that pollinate it

• the type of root structure

• the shape of a plant’s leaves

• The toads were destroyed by the construction equipment.

• The toads got their food from the wetland ecosystem.

Which two changes to Earth helped form this sea arch?

• earthquakes and volcanoes
