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.
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 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.
What are the major factors affecting primary productivity?
The factors affecting primary productivity are as complex as natural ecosystems are.
- Vascular Plants. Vascular plants are overwhelmingly responsible for most of the primary production on land. …
- Algae. …
- Light. …
What is meant by the productivity of ecosystem?
In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume (unit surface) per unit of time, such as grams per square metre per day (g m−2 d−1). The unit of mass can relate to dry matter or to the mass of generated carbon.
What are 5 biotic factors in an ecosystem?
5 Answers. Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
Are there other factors that influence or affect productivity in some of these regions besides sunlight?
Nutrient levels are influenced by a number of other factors, including:
- Soil type.
- Organisms in an ecosystem.
- Nitrogen-fixing bacteria.
- Natural events (volcanic eruption, fires, natural disasters, etc)
- Ocean and/or wind currents.
How does light affect productivity?
Dim lighting tends to cause unnecessary strain on the eyes, which can lead to eye issues or headaches. Employees may experience drowsiness or lose their sense of motivation, which can result in an overall reduction of work productivity. Bright lighting or high-intensity lighting can also affect productivity.
What is the physical factor that affect the primary productivity in a lagoon?
It is evident that changes in environmental conditions (temperature and light) will influence the primary producers, as well as the chemical agents (nutrients) that essentially limit photosynthesis.
