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.

Scientists observe that the deer population is growing and worry there will not be enough plants for the deer during the winter. Which best describes the relationship between the deer population and the plants?
The deer need water stored in plants to survive in winter, but plants do not.
Deer receive energy from eating plants.
The plants are nonliving components.
The plants use oxygen which deer need in order to survive.
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.
Deer grazing in a meadow
Fish using gills to breath
Ants building a mound of soil
Bobcat scratching its claws on a tree
Moose drinking water from a pond
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
Ecologists study the soil particles from a desert biome to learn how the nutrients in the soil sustain plant survival. Which of the following tools is the most beneficial for observing the particles of soil?
Collecting net
Magnet
Microscope
Telescope
After observing an ecosystem, a student writes the following conclusion in a notebook.
Is the student's conclusion logical?
Yes, because ecosystems are made of living things that interact.
No, because ecosystems are made of living and nonliving components.
Yes, because ecosystem is another name for habitat.
No, because an ecosystem has nothing to do with living things.
A pistol shrimp is a burrowing shrimp with poor eyesight. The shrimp digs a hole for both it and the goby fish to live. The shrimp uses it antennae to stay in contact with the tail of the goby fish. When danger approaches, the goby fish swishes its tail and the shrimp quickly hides in the burrow.
Based on the data shown above, what will most likely happen to the shrimp population in 2017?
The population of the pistol shrimp will increase.
The population of the pistol shrimp will decrease.
The population of the pistol shrimp will stay the same.
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.
