Bees fly from flower to flower and pollen sticks to their bodies. The image below shows this interaction.

How does this interaction most benefit flowers?

• Bees are provided with nectar for food.

• Flowers get pollen from other flowers which

  is needed to produce seeds.

• The bees provide oxygen for the flowers

  which is needed to produce more flowers.

• The pollen kills off the bees for its own

  protection

The chart below shows how organisms interact within an ecosystem.

How does the Cecropia tree depend on aztec ants to survive?

• The ants produce a sugary solution for food.

• The ants provide oxygen for the tree.

• The ants keep away other invading organisms.

Trout fish are often found in flowing streams. The picture below shows how beavers build a dam to turn a flowing stream into a still water pond.

What will most likely happen to the trout population in this particular area of the ecosystemWhat will most likely happen to the trout population in this particular area of the ecosystem

What will most likely happen to the trout population in this particular area of the ecosystem?

• The trout population will decrease because its

  natural habitat has been changed.

• The trout population will increase because

  deeper water has been created.

• The trout population will not change.

• The trout population will increase because

  the dam helps protect them.

A liana is a long-stemmed, woody vine that has roots in the soil and climbs up to the canopy of other trees.

How does the action of climbing to the canopy of other trees benefit a liana?

• by absorbing water and providing nutrients

• by exchanging oxygen with the tree

• by reaching sunlight

Kelp forests are large brown algae found in cool shallow waters close to shore and grow in large groups like the image below.

How do kelp forests most likely support populations and communities within an ecosystem?
