Which of the following accurately describes nutrient limitation?a. Nitrogen is typically the limiting nutrient in freshwater environments.
b. Soil environments aren't affected by nutrient limitation.
c. If one essential nutrient within an ecosystem runs out, primary productivity will be limited.
d. Limiting nutrients are the nutrients whose supply is in excess.

Answers

Answer 1
Answer:

Answer is c. If one essential nutrient within an ecosystem runs out, primary productivity will be limited

According to Vitousek et al., 2010, nutrient limitation defined as meaningful additions of an essential element in biologically available forms which increases the rate of primary productivity or increase in the biomass in an ecosystem. Alternately, nutrient limitation may also explained as when the supply of one essential nutrient of the ecosystem runs out the primary productivity of the plants will be limited.
Answer 2
Answer:

Final answer:

Nutrient limitation refers to a situation where an ecosystem or organism's growth is hampered due to lack of a certain essential nutrient. When such a nutrient runs out in an ecosystem, primary productivity is affected as this nutrient is vital for the growth of primary producers.

Explanation:

Nutrient limitation describes a situation in which the lack of a particular essential nutrient prevents an organism or ecosystem from reaching its full growth potential. This concept is very essential in the area of ecology. The correct answer to your question is (c.) 'If one essential nutrient within an ecosystem runs out, primary productivity will be limited.' Let's consider primary productivity in a freshwater ecosystem for example. It is often limited by the availability of nutrients like nitrogen or phosphorous. When these nutrients run out, primary productivity is affected because these nutrients are essential for the growth and development of primary producers (like plants), which set the foundation for energy flow in an ecosystem.
