Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.
This YouTube video investigates the structure and composition of the sun.
This online resource investigates the internal structure, outer layers and surface features of the sun.
These four short online lessons cover the following:
We can analyse the arrows in a food web to identify producers, primary consumers, secondary consumers, and decomposers.
