Gross primary productivity is the amount of carbon fixed during photosynthesis by all producers in the ecosystem. However, a large part of the harnessed energy is used up by the metabolic processes of the producers (respiration). Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance. In other words, it's the rate at which energy is stored as biomass by plants or other primary producers and made available to the consumers in the ecosystem.

Understanding Ecosystem Productivity
Ecosystem productivity refers to the rate at which energy and organic matter are produced in an ecosystem. The statements in question highlight key aspects of primary productivity.
1. Gross Primary Productivity (GPP)
- GPP is defined as the total amount of organic matter produced by photosynthesis in a given area over a specific time period.
- This statement is **correct** as it accurately describes GPP.
2. Net Primary Productivity (NPP)
- NPP is the rate of organic matter that remains after accounting for the energy used by plants for respiration.
- Therefore, NPP is always less than GPP, as some energy is always lost through metabolic processes.
- This statement is **correct** as well.
3. Influence of Plant Species
- Primary productivity indeed varies depending on the types of plant species present in an ecosystem. Different species have varying rates of photosynthesis and growth.
- Thus, the productivity can be significantly influenced by species composition. This statement is also **correct**.
Conclusion
Since all three statements are accurate, the correct answer is option **C: 1, 2, and 3**. Understanding these concepts is crucial for ecological studies and conservation efforts as they provide insights into energy flow and ecosystem health.
