Question

Imagine a very simple ecosystem with one plant species, one species of bacteria, and one species of soil invertebrate that is a shredder. These are the only organisms in this ecosystem. Describe the nutrient cycle of this ecosystem. Include the roles of each of the three species in nutrient cycling- how does nutrient uptake occur for each species, and how does each species return nutrients to the ecosystem for other organisms to potentially use?

Answer 1

◆ NUTRIENT CYCLE :-.

◆ It includes :-

• producers :-
  • plants are producers.
  • Plants require sunlight, water and carbondioxide to produce the food that is required to live or grow.
