GCU BIO-220: Environmental Science
BIO-220 examines human impact on natural resources — ecosystems, water, energy, populations, and pollution — as a popular lab-free science option for non-science majors at GCU. The course leans on applied exercises like ecological-footprint assessments and environmental surveys alongside the standard discussion-and-assignment rhythm.

Build my BIO-220 study planWhat makes it hard
It's friendlier than the anatomy sequence, but the science vocabulary is real — biomes, nutrient cycles, energy systems — and the assignments expect scientific reasoning, not opinion essays about the environment. Students who treat it as a current-events course get caught when questions hinge on the underlying processes.
What you'll cover
- • Ecosystems and biomes
- • The scientific method in environmental science
- • Water resources and pollution
- • Energy: fossil fuels and renewables
- • Human population dynamics
- • Conservation and resource management
The BIO-220 study guide
How to study for GCU BIO-220, step by step.
- 1
Learn the processes under the headlines
BIO-220 questions hinge on mechanisms — nutrient cycles, energy flows, population curves — not environmental opinions. For each topic, make sure you can explain the underlying process, not just the issue.
- 2
Do the applied exercises thoughtfully
The footprint assessments and surveys generate the data your written assignments analyze. Treating them as quick clicks starves the analysis; honest detail makes the write-ups easy.
- 3
Flashcard the ecology vocabulary
Biomes, trophic levels, cycles — the terminology is the course's main memorization load. A small daily deck keeps the science vocabulary from piling up across topics.
- 4
Reason scientifically in discussions
The DQs reward claims tied to course concepts and evidence over environmental sentiment. Cite the process or data behind your position and the rubric points follow.
- 5

FAQ
Is BIO-220 hard?
It's one of GCU's more approachable science options — no lab-practical memorization load. The vocabulary and process questions are the substance; treat it as a science course rather than a current-events course and it's very manageable.
Does BIO-220 satisfy the science requirement?
It commonly fills a general-education science slot for non-science majors at GCU. Confirm against your degree plan, especially if your program specifies a lab science.
What assignments are in BIO-220?
Weekly discussions, written assignments, and applied exercises like ecological-footprint assessments and environmental surveys that feed into the write-ups. The rubrics reward scientific reasoning tied to course concepts.

BIO-201 — Anatomy and Physiology I
BIO-201 is the first half of GCU's anatomy and physiology sequence — cells and tissues, the integumentary, skeletal, muscular, and nervous systems — with a lab component. It's a cornerstone prerequisite for GCU's nursing and health-science pathways, and the grade matters for competitive program admission.
BIO-202 — Anatomy and Physiology II
BIO-202 completes the A&P sequence: endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems, with lab work continuing throughout. Like BIO-201, it's a heavily weighted prerequisite for GCU's nursing and health-science programs.
