What affects productivity in an ecosystem?

What is ecosystem productivity based on?

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 m2 d1). The unit of mass can relate to dry matter or to the mass of generated carbon.

What makes an ecosystem more productive?

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 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 is primary productivity give brief description of factors that affect primary productivity?

Primary productivity refers to the total organic matter produced by primary producers per unit area per unit time. It is affected by nutrient availability, types and number of primary producers present in an ecosystem, temperature, sunlight, water, precipitation etc.

What is primary productivity in ecology?

primary productivity, in ecology, the rate at which energy is converted to organic substances by photosynthetic producers (photoautotrophs), which obtain energy and nutrients by harnessing sunlight, and chemosynthetic producers (chemoautotrophs), which obtain chemical energy through oxidation.

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 are the 5 environmental factors?

Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites.

What are the two main factors affecting primary production?

We focus on two major variables—light and nutrients—and their role in determining primary production.
