Which of the following best describes the role of decomposers in an ecosystem?
They produce energy from sunlight.
They consume primary consumers.
They break down dead organisms and recycle nutrients.
They compete with producers for sunlight.
How does energy flow in a food web?
From top predators to producers
From producers to top predators
In a circular motion
Randomly between organisms
Which of the following statements best explains why energy decreases at each trophic level in a food chain?
Energy is destroyed as it moves up the food chain.
Energy is converted into matter at each level.
Energy is lost as heat at each level.
Energy is stored indefinitely at each level.
What is the role of a model in understanding the cycling of matter in an ecosystem?
It provides a detailed list of all species in the ecosystem.
It visually represents the flow of energy and matter.
It predicts the weather patterns in the ecosystem.
It shows the exact number of organisms in each trophic level.
Which of the following is an example of a nonliving component that plays a role in the cycling of matter in an ecosystem?
Plants
Animals
Water
Decomposers
How does the removal of a top predator affect the flow of energy in an ecosystem?
It increases the energy available to producers.
It decreases the energy available to primary consumers.
It disrupts the balance and can lead to overpopulation of certain species.
It has no effect on the ecosystem.
Which of the following best describes the cycling of matter in an ecosystem?
Matter is created and destroyed as it moves through the ecosystem.
Matter is recycled and reused by different organisms.
Matter flows in one direction and is not reused.
Matter is only used by producers and decomposers.
