What makes an ecosystem have high productivity?
What makes an ecosystem have high 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 are 2 main factors that influence the productivity of an ecosystem?
Two Factors That Influence Photosynthesis and Photosynthetic Productivity. Looking at these requirements for photosynthesis, it makes sense that sunlight and nutrient availability are the factors influencing primary productivity in ecosystems since those are the factors required for photosynthesis to occur.
Which has high productivity in ecosystem?
Tropical rainforests show the highest productivity in terrestrial ecosystems.
What causes high productivity in the ocean?
The proximity to land and its nutrient sources, the interception of sinking organic matter by the shallow seafloor, and the propensity for coastal upwelling all result in highly productive ecosystems.
Why do tropical rainforest have high productivity?
In Tropical Rainforests, water, sunlight, and high temperatures are consistent and a dense concentration of plants is present, causing both the GPP and NPP to be very high. So, high levels of productivity increase biomass.
Which has highest productivity?
Coral reef ecosystem has highest gross primary productivity due to availability of large number of autotrophs per unit area.
What world ecosystem have high and low net productivity Why?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.
What are the major factors that affect the primary productivity in aquatic ecosystem?
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 do tropical rainforests have high productivity?
What is productivity in an ecosystem?
In ecology, productivity refers to the rate of formation of biomass in the ecosystem. It can also be referred to as the energy accumulated in the plants by photosynthesis.
What type of currents cause high primary productivity?
Two types of current motion, upwelling and downwelling, strongly influence the distribution and abundance of marine life. Currents play a huge role in marine productivity, through a process called upwelling.
Why is there high productivity at the equator?
To replace it, nutrient-rich water is drawn up from the ocean depths, bringing a steady supply of nutrients to the sunlit surface and producing a band of consistently high primary productivity at the equator.
