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.
Part 1: Proper, improper and mixed fractions
Part 2: Examples of proper, improper and mixed fractions
Part 3: Common mistakes and misconceptions
This online activity is a math game on rounding numbers.
This is an online activity that provides you with various exercises on rounding whole numbers.
Use two methods to find the sum of mixed numbers: improper fractions and mixed numbers
We can analyse the arrows in a food web to identify producers, primary consumers, secondary consumers, and decomposers.
