The apple is ripening from the inside. Ripening occurs due to injury or infection by fungi (the signal causes ripening chemicals to be released in the fruit). The fruit becomes soft as it ripens, which accounts for the dents.

At this point, microbes have attacked the fruit and will eventually digest the fruit into its smallest parts.

Inside the skin, microbes are breaking down the flesh into nutrients and water. If you were to poke a hole in the skin, the inside would likely consist of brown and sticky liquid.

Microbes will continue to break down the fruit skin and flesh until all the water and nutrients are absorbed into the soil below. These nutrients then nourish growing plants.

Forest food web Illustration

The lowest level of a food web includes producers, which are plants that make their own energy from the sun. Animals that eat these producers are called primary consumers, and consumers that eat other consumers are called secondary consumers. Decomposers break down dead plants and animals to release nutrients into the soil.

Worm Experiment Week 12

This image is a good example of conservation of matter. Although the piles have shrunk, matter has changed from leaves to water and nutrients (such as nitrogen and phosphorous), but no matter was lost.

At week 4, evidence of earthworm decomposition is beginning to show. The earthworm is eating the dead material and releasing smaller forms of matter into the container.

Worm Experiment Week 8
Conditions of Use:
No Strings Attached
Rating

At week 8, the impact of an earthworm on decomposition is obvious and the material in the worm container is beginning to appear as compost. Keep in mind that the material within the worm-free container will decompose due to oxygen and bacteria, but at a much slower rate than the container with earthworms.
