5.9.A

This question has two parts.  First answer Part A, then answer Part B.

Students learn the following information about a strangler fig.

In the rainforest, strangler fig seedings begin growing on other trees, wrapping roots around the host tree.  When the roots reach the ground, the strangler fig takes root and grows larger than the host tree, taking nutrients from the host tree and growing to the height of the rainforest canopy.

Colorado elk need food, water, and air to sustain their population. Based on this information, what statement is true regarding the elk's ecosystem?

Elk lack dependence on living and nonliving components in their environment.

Too many factors limit the elk's survival within their ecosystem.

Living organisms are independent of nonliving components within an ecosystem.

Living and nonliving components work together to keep the elk's ecosystem functioning.

Which of these are examples of relationships between living organisms and another living organism in an ecosystem?

Select TWO correct answers.

A group of students uses their outdoor classroom to investigate the way organisms live and survive in their ecosystem. They notice a trail of ants carrying bits of food into a mound of dirt. The students are making –

a hypothesis

an observation

a conclusion

a graph

Part A
How does the strangler fig interact with other living components in its ecosystem in order to survive?

The fig produces its own food through the process of photosynthesis.

The fig competes with other trees for sunlight.

The fig roots rot in the wet rainforest soil.

Part B
What evidence supports your answer to Part A?

It rains every day in the rainforest ecosystem, which provides the fig with enough water to survive.

The rainforest floor does not receive much sunlight, so the fig must grow taller than other trees.

Producers, like the fig, make their own food, while consumers obtain food from other organisms.

Plants convert carbon dioxide, water, and sunlight into glucose, which are living components in the rainforest ecosystem.
