A translocation in which part of one chromosome is exchanged with a part of a separate non-homologous chromosome. ~ s are the result of moving a section of the genetic material (chromosome) of the cell and attaching it to another chromosome.
Plants actually create these compounds to ensure a healthy, diverse population of bacteria lives near their roots to protect the plants. Decomposers are especially important in retaining nutrients in their cells thus preventing loss of those nutrients from the root zone. This is very important in the nitrogen cycle.
A limiting nutrient is a nutrient necessary for plant growth, but available in a concentration insufficient to support continued growth. Once supply of this nutrient is exhausted, plant growth ceases regardless of other remaining nutrient quantities. Any nutrient can become a limiting nutrient in an ecosystem. For algae, the most obvious limiting nutrients are nitrogen, certain metals and phosphorus. Nitrogen removal is an expensive process, involving high energy and chemical costs and specialised equipment.
