What 3 factors affect 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.

What are the 3 most productive types of ecosystems?

The world’s ecosystems vary tremendously in productivity, as illustrated in the following figures. In terms of NPP per unit area, the most productive systems are estuaries, swamps and marshes, tropical rain forests, and temperate rain forests (see Figure 4).

What are 3 factors that might affect the primary productivity of a body of water?

On land, it is driven by temperature and availability of water and nutrients modified by land use. In aquatic ecosystems, primary productivity is driven by the availability of nutrients and light and, to a lesser extent, by temperature and other factors.

What 3 ecosystems 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.

What factors affect ecosystems?

They include factors such as light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components.

What makes an ecosystem highly productive?

A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable. … Trunks and roots trap large amounts of food particles and, once their vital cycle is over, they decompose, thus supplying the ecosystem with more organic matter.

Which ecosystems have the highest productivity?

Tropical rainforests show the highest productivity in terrestrial ecosystems.

What are the four major factors that affect lake productivity?

The relative importance of the phytoplankton, periphyton, and macrophyte contributions to the total primary pro- duction depends on basin morphology, water clarity, substrate suitability, and the extent of water level fluc- tuations.

What factors affect productivity in the ocean?

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.

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.

What affects net primary productivity?

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 3 basic steps for all other matter cycles?

The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle.

What factors are most critical in affecting the net primary productivity of a terrestrial ecosystem?

Four principal abiotic factors usually limit the amount of NPP on land – light, water, temperature, and mineral nutrients – and all these abiotic factors are changing rapidly as a result of human activity, with highly uncertain impli- cations for global and local NPP.

What are the three factors that control the balance of an ecosystem?

There are four factors that control the balance of an ecosystem: the water cycle, the mineral cycle, energy flow and community dynamics.

What are the 5 factors of an ecosystem?

What are 5 abiotic factors that can impact our ecosystems? Five common abiotic factors are atmosphere, chemical elements, sunlight/temperature, wind and water.

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.
