Many plants that grow in tropical rain forests have specialized roots that anchor them to the branches and trunks of trees. They do not harm the trees. These plants get food and water from various sources, including the air and dead organic matter found on the trees.One example of these plants found in tropical rain forests is the bromeliad. Its leaves form a cup-like structure that is able to hold water. This water provides a feeding and breeding area for many insects and frogs. Snakes and lizards also come to these plants in search of food and water. A cross-section showing the inside of a bromeliad is shown below.

For the question, "In which set is a biotic factor paired with an abiotic factor?" the correct answer is A) producers and sunlight. To determine this, you need to understand the terms "biotic" and "abiotic." Biotic factors refer to living or once-living components of an ecosystem, such as plants or animals, while abiotic factors refer to non-living components, such as sunlight, temperature, or humidity. In option A, producers (which are biotic factors) are paired with sunlight (which is an abiotic factor), making it the correct answer.
For the question, "Which list contains only abiotic factors?" the correct answer is A) water temperature, amount of sunlight, and soil type. Again, you need to understand the difference between biotic and abiotic factors. Biotic factors are living or once-living components, while abiotic factors are non-living components. In option A, water temperature, amount of sunlight, and soil type are all abiotic factors, so it is the correct answer.
For the question, "Trout are found in rapidly flowing streams that have high levels of oxygen, stony bottoms, and an abundance of aquatic insects. These streams represent a trout’s ______________." the correct answer is C) habitat. The habitat is the specific environment in which an organism lives, including its physical surroundings and the other organisms present. In this case, the rapidly flowing streams with high levels of oxygen, stony bottoms, and abundant aquatic insects provide the specific habitat for trout.
For the question, "Predators often feed on weak or sick animals in an ecosystem. The role of the predator is described as its ___________." the correct answer is C) niche. A niche refers to the specific role or position an organism has within an ecosystem, including its interactions with other organisms and its use of resources. Predators play a specific role in feeding on weak or sick animals, which is their niche.
For the question, "Many plants that grow in tropical rainforests have specialized roots that anchor them to the branches and trunks of trees. They do not harm the trees. These plants get food and water from various sources, including the air and dead organic matter found on the trees. One example of these plants found in tropical rainforests is the bromeliad. Its leaves form a cup-like structure that is able to hold water. This water provides a feeding and breeding area for many insects and frogs. Snakes and lizards also come to these plants in search of food and water. A cross-section showing the inside of a bromeliad is shown below. Which of these types of organisms break down dead organic matter in the rainforest?" the correct answer is D) decomposers. Decomposers are organisms that break down dead organic matter and recycle nutrients back into the ecosystem. They play an essential role in nutrient cycling and decomposition.

Snakes and lizards also come to these plants in search of food and water. A cross-section showing the inside of a bromeliad is shown below. Which of these terms best describes the wide variety of plant and animal species in the rainforest?" the correct answer is B) biodiversity. Biodiversity refers to the variety of plant and animal species present in an ecosystem. Tropical rainforests are known for their high levels of biodiversity.
