Multiple Choice

In the context of organic chemistry, how does nutrient availability affect primary productivity in ecosystems?

Nutrient availability has no effect on primary productivity.

Nutrient availability increases the rate of photosynthesis, leading to higher primary productivity.

Nutrient availability only affects secondary productivity, not primary productivity.

Nutrient availability decreases the rate of photosynthesis, leading to lower primary productivity.

Verified step by step guidance

Understand the concept of primary productivity: Primary productivity refers to the rate at which energy is converted by photosynthetic and chemosynthetic autotrophs to organic substances. It is a measure of the energy input into an ecosystem.

Recognize the role of photosynthesis in primary productivity: Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. This process is fundamental to primary productivity.

Identify the importance of nutrient availability: Nutrients such as nitrogen, phosphorus, and potassium are essential for plant growth and photosynthesis. They act as building blocks for vital molecules like chlorophyll, which is crucial for capturing light energy.

Analyze the effect of nutrient availability on photosynthesis: When nutrients are abundant, plants can produce more chlorophyll and other necessary compounds, enhancing their ability to perform photosynthesis efficiently, thus increasing primary productivity.

Conclude the relationship between nutrient availability and primary productivity: Increased nutrient availability generally leads to higher rates of photosynthesis, resulting in greater primary productivity in ecosystems. This is because plants can grow more vigorously and capture more energy from sunlight.
