Generate scientifically accurate food web diagrams for ocean, forest, grassland, arctic, freshwater, and desert ecosystems. Describe what you need and download a labeled, classroom-ready diagram in seconds.
Your first diagram is free — no sign-up needed (2K with watermark)
Describe your ecosystem on the left to generate your own food web
Stop dragging icons around a canvas or searching textbook scans. Describe the ecosystem you need — producers, consumers, decomposers, and trophic levels — and the food web maker generates a labeled diagram in seconds.
Pick an ecosystem (ocean, forest, grassland, freshwater, desert, arctic) and list the organisms you want shown. Specify whether you need a labeled food web, a blank labeling worksheet, or a color-coded trophic level diagram.
The food web maker maps producers at the base, herbivores and carnivores at higher trophic levels, and draws energy flow arrows from prey to predator. Decomposers are added when requested. Ready in under 60 seconds.
Export as 2K or 4K PNG with a clean white background — ready for worksheets, lecture slides, or lab reports. 300 DPI keeps labels sharp on classroom printouts and projectors.
Students · Biology Teachers · Homeschool Parents
Whether you need a labeled ocean food web for a 5th grade project or a complex temperate forest food web for AP Environmental Science, this generator handles the diagram so you can focus on the ecology.
Middle school through college
You know which organisms belong in your ecosystem — you just need a clean diagram for the assignment. Generate a food web with the right producers, consumers, and trophic levels in under a minute.
K-12 and university ecology instructors
Create labeled food webs for lectures, blank versions for student labeling activities, and ecosystem-specific diagrams for unit tests. Each food web matches your lesson plan instead of a textbook figure you cannot edit.
Teaching ecology at home
Generate age-appropriate food web diagrams without searching dozens of websites for the right ecosystem. Describe the complexity level you want — a 5-organism pond food web for younger kids or a full forest food web for high schoolers.
Six ecosystems, ready to remix
Every diagram below was generated from a plain-text description. Click any example to load the prompt and try it for your own ecosystem.
Phytoplankton through sharks with energy flow arrows
Oak trees, deer, mice, foxes, hawks and decomposers
Algae, water fleas, frogs, herons and bacteria
Lichens through polar bears in a cold biome
Cacti, kangaroo rats, snakes, hawks and coyotes
Arrows drawn, organism boxes left empty for labeling
Most diagram tools give you a blank canvas and clipart. This food web generator understands trophic levels, energy flow, and ecosystem-specific species — and draws them in the conventions used in biology textbooks.
Producers, Consumers, Apex Predators
Producers sit at the base, primary consumers above them, secondary and tertiary consumers higher up, and apex predators at the top. Decomposers attach to the side. The food web maker follows the same hierarchy used in AP Biology and ecology textbooks.
Six Built-In Ecosystem Types
Generate ecosystem-specific food webs for ocean, freshwater, temperate forest, grassland, arctic tundra, and desert biomes. The food web generator picks the right producers and consumers for each environment instead of mixing unrelated species.
Standard Ecology Convention
Every feeding arrow goes from the organism being eaten to the organism doing the eating — the convention used in textbook food webs. No reversed arrows, no missing connections, no ambiguous lines.
One Tool, Multiple Worksheet Types
Generate a fully labeled food web for a study guide, a blank version with empty boxes for labeling practice, or a partially labeled diagram with only producers shown. Just describe what you need in plain English.
Faster Than Searching Google Images
Type the ecosystem and species you want, click generate, and download a print-ready food web. No more scrolling past low-resolution stock images, watermarked diagrams, or unlicensed textbook scans.
300 DPI, Clean White Background
Every food web exports at 300 DPI with a white background — ready to paste into a worksheet, quiz, or lab report. High contrast keeps labels readable even on black-and-white printers and overhead projectors.
Every account gets free credits on sign-up. Need more food web diagrams for an ecology unit or a full semester of biology lessons? Pick a plan that fits your workload.

Feedback from biology teachers, ecology students, and homeschool parents who stopped redrawing food webs by hand and stopped scrolling through low-quality search results.
Megan Carter
AP Environmental Science Teacher, Lakeside High SchoolI needed an ocean food web for our unit on marine ecosystems and a separate one for tundra. Generated both in under three minutes — full trophic levels, decomposers, the works. My students could actually read the labels.
Diego Ramirez
8th Grade Science Student, Greenwood MiddleFor my freshwater pond project I described which fish, frogs, and birds I wanted. The food web came out clean enough to staple straight into my report — way better than my hand-drawn arrows.
Dr. Amara Okafor
Ecology Lecturer, University of Cape TownI generate fresh food web diagrams for each lecture instead of recycling the same textbook figure. The trophic levels are accurate and the arrows go the right direction — which is more than I can say for half the food webs on Google.
