This Florida Biology 1 EOC Practice Test page provides five short practice sets with 10 original multiple-choice questions each. The sets support Biology 1 EOC readiness with cells, homeostasis, energy flow, genetics, DNA, evolution, ecology, populations, scientific investigation, and biological evidence.

Biology 1 skills covered

  • Cell structures, membranes, transport, organelles, enzymes, ATP, cell division, and homeostasis
  • Photosynthesis, cellular respiration, food webs, trophic levels, energy transfer, decomposers, and nutrient cycling
  • DNA, RNA, protein synthesis, heredity, Punnett squares, mutations, meiosis, natural selection, and common ancestry
  • Population growth, carrying capacity, symbiosis, habitat fragmentation, carbon cycling, biodiversity, and conservation
  • Integrated biology reasoning with experimental variables, ecosystem services, evidence, models, and claim-evidence-reasoning explanations

How to use this page

Complete one 10-question set at a time. Use the model, data, or biological process in each question as evidence. Review the explanation after each response and note whether the missed skill involves structure, energy, inheritance, ecology, or investigation.

This is supplemental State Test Practice, State Assessment Practice, and Standardized Test Practice for Florida Biology 1 EOC preparation. It does not replace current Florida Department of Education guidance, official assessment materials, accommodations, or testing policies.

Cells use glucose and oxygen to produce carbon dioxide, water, and usable ATP.

3. QuestionMultiple choice

In a food chain, grass is eaten by grasshoppers, which are eaten by frogs. Which organism is the producer?

Please select an answer first.

Correct answer: C

The correct answer is Grass.

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: Grass makes its own food through photosynthesis, so it is the producer.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

Grass makes its own food through photosynthesis, so it is the producer.

4. QuestionMultiple choice

Why is less energy available at each higher trophic level?

Please select an answer first.

Correct answer: D

The correct answer is Organisms use much of the energy they obtain for life processes and release some as heat..

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: Energy is transferred inefficiently, and organisms use much of it for metabolism.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

Energy is transferred inefficiently, and organisms use much of it for metabolism.

5. QuestionMultiple choice

Which process breaks down glucose to release energy for cell activities?

Please select an answer first.

Correct answer: A

The correct answer is Cellular respiration.

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: Cellular respiration breaks down glucose and transfers energy to ATP.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

Cellular respiration breaks down glucose and transfers energy to ATP.

6. QuestionMultiple choice

A plant is kept in darkness for several days. Which process is directly limited?

Please select an answer first.

Correct answer: B

The correct answer is Photosynthesis.

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: Photosynthesis requires light energy, so it is directly limited in darkness.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

Photosynthesis requires light energy, so it is directly limited in darkness.

7. QuestionMultiple choice
