Which statement describes one way plants depend on nonliving parts of their environment?
A. Insects pollinate flowering plants.
B. Plants use sunlight to make their own food.
C. Animals eat plants for energy.
D. Vines grow around tree trunks for support.
✅ Correct Answer: B
Plants need sunlight, which is a nonliving part of the environment, to make their own food through photosynthesis. This shows that plants depend on a nonliving factor to survive.
Why the other answers are incorrect:
A. Insects are living things, so this describes a relationship between living organisms.
C. Animals are living things, so this also describes a relationship between living organisms.
D. Tree trunks are part of living trees, so this is a relationship between living things.

A. The bottle cap is more dense than syrup and less dense than oil.
B. The bottle cap is less dense than water and syrup and more dense than oil.
C. The key is less dense than syrup and more dense than water.
D. The key is more dense than syrup, water, and oil.

Cactus plants and desert foxes both live in the desert. The cactus stores water in its thick stem to survive in the hot, dry climate.
Which statement describes a relationship between a living and a nonliving component in this scenario?
A. The desert fox hunts small animals for food.
B. The cactus stores water from the desert environment.
C. The desert fox competes with other foxes for territory.
D. The cactus provides shelter for insects.
✅ Correct Answer: B
The cactus is a living thing, and water is a nonliving part of the desert environment.
When the cactus stores water, it is interacting with a nonliving component. This shows a relationship between living and nonliving things.
Why the other answers are incorrect:
A. This describes a relationship between two living things (a fox and its prey).
C. This describes competition between two living animals.
D. This describes a relationship between two living things (a cactus and insects).

The mistletoe plant is found growing on trees in many regions.
The roots of this plant grow into tree branches and absorb water and nutrients from the tree.
Which statement describes another way that this interaction between the mistletoe and the tree helps the mistletoe survive in its environment?
A. The mistletoe is protected from animals that eat plants.
B. The mistletoe reduces the tree’s growth so it has more access to sunlight.
C. The mistletoe grows at a different time of year than the tree.
D. The mistletoe grows high on tree branches, where it can receive more sunlight.
✅ Correct Answer: D
Mistletoe grows high in tree branches, where it gets more sunlight. Sunlight helps the plant make its own food, so this helps it survive.
Why the other answers are wrong:
A. Being higher up might help a little, but protection from animals is not the main reason it survives.
B. The mistletoe does not survive by slowing the tree’s growth.
C. Growing at a different time of year does not explain how this interaction helps it survive.
