Solution
The correct answer is a. producers and decomposers.
Here's why:
In an ecosystem, producers (like plants) create their own food through photosynthesis. They take in carbon dioxide from the air, water from the ground, and energy from the sun to create glucose, a type of sugar that they use for energy. In this process, they also release oxygen into the air.
Decomposers (like bacteria and fungi) play a crucial role in recycling nutrients in an ecosystem. When a plant or animal dies, decomposers break down the dead organisms and return the nutrients to the soil. This allows the nutrients to be reused by producers in the process of photosynthesis.
So, at a minimum, an ecosystem must have producers and decomposers to recycle nutrients. While primary and secondary consumers (herbivores and carnivores) are important for other reasons in an ecosystem, they are not necessary for
