You asked: Which best determines 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 determines the productivity of an ecosystem quizlet?

What determines the productivity of an ecosystem? Via photosynthesis, producers are able to capture solar energy. Gross primary productivity (GPP) measures this over a given amount of time. How efficiently is energy transferred between trophic levels in an ecosystem?

Why are ecosystem boundaries hard to define?

While some are very defined, others are difficult to calculate. You would have to look at the abiotic and biotic components to know if you left one ecosystem to another. … Ecosystem boundaries imposed by humans are often incorrect as most of them are placed by administrative rather than scientific criteria.

What is an ecosystem and what are its components?

An ecosystem is a group or community composed of living and non-living things and their interactions with each other. … Every ecosystem has two components, namely, biotic components and abiotic components. Biotic components refer to all living organisms in an ecology while abiotically refers to the non-living things.

Which unit is the most appropriate to express the gross primary productivity of an ecosystem?

As such it is available for consumption by herbivores. Both gross and net primary production are typically expressed in units of mass per unit area per unit time interval. In terrestrial ecosystems, mass of carbon per unit area per year (g C m2 yr1) is most often used as the unit of measurement.

What factors determine 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 determines the productivity of an ecosystem apes?

What determines the productivity of an ecosystem? The amount of energy in an ecosystem, determines how much life it can support. … They are fairly low as if there is the total biomass available at a given trophic level, only about 10% is only converted to the next trophic level as energy.

What determines the boundaries of an ecosystem?

Many real ecological boundaries are defined by a change in several more or less congruent ecological properties: A forest–field edge, for example, could be defined by vegetation height, vegetation species, animal species, wind resistance, or light penetration.

Do ecosystems always have well defined boundaries?

Not all ecosystems have well defined boundaries. Caves, fore example, have really well defined boundaries, since they have distinctive biotic and abiotic components. Aquatic ecosystems tend to have well defined boundaries as well. Terrestrial ecosystems have more subjective boundaries.

How might we determine where one ecosystem ends and another begins?

it is hard to determine where one ecosystem ends and another begins – but not impossible – look for a change in abiotic & biotic components and topographic features. … They are boundaries placed by humans to separate ecosystems while natural boundaries are boundaries put in place naturally by nature.

What makes up an ecosystem?

An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. … Abiotic factors include rocks, temperature, and humidity.

What are the two factors of an ecosystem?

The environment includes two types of factors: abiotic and biotic.

  • Abiotic factors are the nonliving aspects of the environment. They include factors such as sunlight, soil, temperature, and water.
  • Biotic factors are the living aspects of the environment.

What are the main components of ecosystem?

Q.3 The major components of an ecosystem are

It consists of two major components, biotic or living components and nonbiotic or nonliving components. Biotic components include plants, animals, decomposers. Nonliving components include air, water, land.
