Producer — Science definition
Defined in 2 courses:
- An organism that builds organic matter using an energy source rather than feeding on organic food. (Science 6: Matter, Energy & Earth Systems)
- An organism building its own food from simple materials using an outside energy source, almost always light. (Life Science & Scientific Inquiry)
Where it is taught
- Food Chains, Food Webs & Energy Flow — Ecosystems, Watersheds & Conservation, Science 6: Matter, Energy & Earth Systems, Grade 6
- Energy Flow, Food Chains & Food Webs — Ecosystems, Matter & Energy, Life Science & Scientific Inquiry, Grade 7
In use
They are the only entrance: every other organism in an ecosystem is living on energy a producer captured, whether it eats plants directly or eats something that did.
Food Chains, Food Webs & Energy Flow
A producer builds its own food from simple materials using an outside energy source — almost always a plant or alga using light.

Questions using producer
Problem 1
- One illustrative result establishes every real condition and needs no further evidence.
- Food-web arrows always point from predator toward prey.
- Every feeding transfer has exactly the same universal percentage.
- producer: An organism that builds organic matter using an energy source rather than feeding on organic food.
Answer and explanation
producer: An organism that builds organic matter using an energy source rather than feeding on organic food.
An organism that builds organic matter using an energy source rather than feeding on organic food. The arrows show receiving organisms obtaining matter and energy from resources. 80 ÷ 800 = 10% in the stated biomass-transfer model, not a universal percentage. The second fish provides another feeding route, and the web lacks population sizes and rates; it cannot specify an exact future bird count.
