Chapter 38, Problem 2PIT
Summary Introduction
To add:
Another concept map that show nutrient cycle on land include producer, consumer, carbon, nitrogen, phosphorus atmosphere and soil
Concept introduction:
The producers are basically the plants which prepare their own food and other organism depends on them for their survival. Consumers are those organisms who depend upon plants for their food. Decomposers help in the breakdown of complex molecule to simpler ones. Nutrient cycle include carbon, nitrogen, phosphorus cycle due to which energy flow takes place.

Students have asked these similar questions
21. Decomposers are critical in the nitrogen and phosphorus cycles because they:
are responsible for the fixation of the nutrients into a bioavailable form
allow for the cycling of the nutrients within the biosphere
are involved in processes that return the nutrients to their major reservoirs
More than one of these choices is correct.
10. Describe the process and importance of nutrient cycling in ecosystems.
1. Using the figure below, generate a food chain with four trophic
levels, and identify each level
