  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Fossils provide evidence about organisms that lived in the past and changes across geologic time.

5. QuestionMultiple choice

In a food web, what is likely to happen if a top predator is removed?

Please select an answer first.

Correct answer: A

The correct answer is Some prey populations may increase..

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Removing a predator can reduce predation on its prey, causing prey numbers to rise.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Removing a predator can reduce predation on its prey, causing prey numbers to rise.

6. QuestionMultiple choice

Why does an energy pyramid usually have less available energy at higher levels?

Please select an answer first.

Correct answer: B

The correct answer is Energy is transferred and some is released as heat at each level..
