Healthy ecosystems have an energy source, usually the sun . ... Decomposers break down dead plants and animals, returning vital nutrients to the soil.
What does every ecosystem need?
An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems require energy from an external source – this is usually the sun. An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter.
Which is the smallest ecosystem?
Microbiomes are communities of bacteria, fungi, protozoa, algae, other one-celled microbes, and viruses that interact with one another in complex ways. These ecosystems are enormously complex. A few grams of soil or marine sediment might contain as many as several hundred thousand different species of microbes.

What is the structure of an ecosystem?
Ecosystem structure is a network of interactions between abiotic and biotic components of the system . The biotic structure of the ecosystem is characterized by the composition of the biological community including species numbers, biomass, life-form, life-history and spatial distribution of species.
What is the difference between biotic and abiotic?
Description. Biotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components ; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem.
