Question: What factors determine the productivity of an ecosystem?

Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.

Which of the factors affect productivity?

What are the factors affecting ecosystem?

Biotic factors include plants, animals, and their interaction such as grazing, predation, invasive species, etc. Abiotic factors include light, temperature, pressure, humidity, earthquake, volcanic eruptions, etc. Pollution and destruction of natural habitat is the major influence due to human activities.

What two main factors determine ocean productivity?

Abiotic factors like solar radiation and nutrients, and biotic factors like zooplankton predation may affect ocean primary productivity. Productivity varies with the season, and also locally and globally.

What factors affect the productivity of an aquatic ecosystem?

In aquatic ecosystems, primary productivity is driven by the availability of nutrients and light and, to a lesser extent, by temperature and other factors. Primary productivity is important because it is the process that forms the foundation of food webs in most ecosystems.

How do you determine productivity?

Overall employee labor productivity is calculated by dividing the goods and services produced by the total hours a company’s employees during a certain period of time. For example, suppose a manager wants to calculate the productivity of all the employees at their company.

What are the most important three factors in ecosystem?

Are the most important three factors in ecosystem? Biotic components include plants, animals, decomposers. Nonliving components include air, water, land.

What are the 2 factors of ecosystem?

The environment includes two types of factors: abiotic and biotic. Abiotic factors are the nonliving aspects of the environment. They include factors such as sunlight, soil, temperature, and water. Biotic factors are the living aspects of the environment.

What are the most critical factors responsible for the ecosystem changes?

The most important direct drivers of change in ecosystems are habitat change (land use change and physical modification of rivers or water withdrawal from rivers), overexploitation, invasive alien species, pollution, and climate change.

What factors increase primary productivity?

A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable. The presence of some forms of secondary energy can also help to increase the primary productivity rate.

What factors determine the productivity of a lake?

Levels of temperature and dissolved oxygen are among the factors affecting the productivity. In general, the dominance of Bacillariophyceae in the lake plays an important role in productivity, where it represented more than 65 % to the total count of phytoplankton during the period of study.

Why does light affects the productivity in an ecosystem?

Light. Energy from the sun is essential to the process of photosynthesis, by which most primary production gets done. This has a large effect in the oceans, where, because of the limits of light penetration, it is necessary for most production to take place near the surface.
