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.
Why do different ecosystems have different productivity?
The largeness of primary productivity depends on the photosynthetic capacity of producers and the existing environmental conditions, such as solar radiation, temperature and soil moisture.
What are the different types of productivity in an ecosystem?
According to Odum there are three types of productivities – primary productivity, secondary productivity and community productivity.
Why Some ecosystems are more productive than others?
Why are some ecosystems or biomes more productive than others? Tropical rainforest: High productive rate because warm temp is ideal for photosynthesis, and high global productivity. Open oceans: Low rates of production, but ALOT of global productivity. … We depend on ecosystems for goods and services.
What do you mean by productivity of an ecosystem What are the types of productivity also mention the factors on which productivity of an ecosystem depends?
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.
Why does the primary productivity vary from ecosystem to ecosystem?
Primary productivity varies from ecosystem to ecosystem because it depends on the plant species inhabiting the area and their photosynthetic activity. It also depend on various environmental factors.
Why do different ecosystems vary?
It depends upon the type of plant species associated with an ecosystem, photosynthetic capacity of these plants and nutrient availability. This is the reason why it varies in different types of ecosystems.
Why is productivity important to an ecosystem?
Ecosystems have characteristic amounts of biomass at each trophic level. … The productivity of the primary producers is especially important in any ecosystem because these organisms bring energy to other living organisms by photoautotrophy or chemoautotrophy.
How does species diversity affect ecosystem productivity?
Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
What are the environmental factors affecting the production process in an ecosystem?
Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition. It is important to understand how these factors affect plant growth and development.
What factors improve productivity?
A brief analysis of five major factors as a perspective to enhance productivity is discussed in the following sub-sections.
- Positive attitude and involvement of management. …
- Proactive employee. …
- Good working condition. …
- Tool and equipment to raise productivity. …
- Availability of input supplies.
Are some ecosystems more productive than others?
Summary: Ecosystems containing several species are more productive than individual species on their own.
Which 3 ecosystems have the highest productivity and which 3 have the lowest productivity?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
