Life Science: Producers, consumers and decomposers
Written by Adi Ackerman, Head Teacher
"Life Science: Producers, consumers and decomposers" is written for 4th Grade (Ages 9-10), and it covers NGSS 4-LS1-1. If your little one is a year younger but already steady on ecosystems, the page still works. You may just need to read the instructions out loud. And if they are older and producers, consumers and decomposers never quite stuck, this is a short review rather than busywork.
4th grade science worksheet: Producers, consumers and decomposers. Sort each living thing into the correct group. Part of our producers, consumers and decomposers ecosystems collection. Aligned to NGSS standards.
How do I use this worksheet?
Start with something students can look at or think about: a photo, a short video, a jar on the windowsill, or a question like "what do you already know about producers, consumers and decomposers?" Then let them work through it independently, since students at this age benefit more from productive struggle than from being walked through each step, keeping a word bank or anchor chart in view so the vocabulary stays available. When you review, ask students how they knew, and let them point to the part of the diagram or reading that told them. These producers, consumers and decomposers worksheets work well as a lead in before an investigation, as a way to capture what students noticed afterward, or as review before an assessment.
What students will practice
- Students will observe and describe producers, consumers and decomposers using accurate science vocabulary.
- Students will gather evidence about producers, consumers and decomposers from diagrams, readings, data, and their own investigations.
- Students will use what they learn about producers, consumers and decomposers to explain what they see and answer questions about the world around them.

What does this worksheet teach?
⌄
These producers, consumers and decomposers worksheets for 4th grade give students a clear, visual way to work through one of the big ideas in ecosystems. Students label diagrams, sort and classify examples, read short explanations, and answer questions that ask them to say why, not just what. Each page keeps the science vocabulary front and center so students leave with the words they need to talk about producers, consumers and decomposers accurately. Working through producers, consumers and decomposers on paper gives 4th grade students something concrete to hold onto before, during, or after the hands on part of a lesson.
Can I use this producers, consumers and decomposers worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 4th Grade ecosystems, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with producers, consumers and decomposers. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
How many 4th Grade producers, consumers and decomposers worksheets are there?
⌄
1 printable worksheet, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.
What age are producers, consumers and decomposers worksheets for?
⌄
These are written for 4th Grade students, roughly ages 9-10. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.
Are these producers, consumers and decomposers worksheets aligned to NGSS?
⌄
Yes. Each one shows the NGSS code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.
