What is primary production and how is it measured?
Primary production is the synthesis of organic compounds by autotrophic organisms using light or chemical energy. It can be measured using techniques like oxygen production, carbon assimilation, or biomass accumulation over time. These methods help quantify the rate at which energy is converted into organic matter by plants and other photosynthetic organisms.
What does net primary productivity result in?
is the production of organic compounds from atmospheric or aquatic carbon dioxide, principally through the process of photosynthesis, with chemosynthesis being much less important. All life on earth is directly or indirectly reliant on primary production. The organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these are mainly plants, while in aquatic ecoregions algae are primarily responsible. Primary production is distinguished as either net or gross, the former accounting for losses to processes such as cellular respiration, the latter not.
How does a biomass pyramid differ by showing each tropical level?
A biomass pyramid displays the total biomass at each trophic level in an ecosystem. In a typical pyramid, the biomass decreases as you move up the trophic levels, with primary producers at the base having the most biomass. In a tropical ecosystem, the biomass pyramid may be inverted due to high turnover rates and rapid growth and reproduction of organisms, leading to a larger biomass of consumers compared to producers.
What is the biomass of a first order heterotroph?
The biomass of a first-order heterotroph, typically represented by primary consumers like herbivores, refers to the total mass of living organisms that consume primary producers (plants or phytoplankton) for energy. This biomass can vary significantly based on the ecosystem, availability of food sources, and environmental conditions. In ecological studies, it is often measured to understand energy transfer through trophic levels and the overall health of an ecosystem.
How do you transformation oxidized carbon?
primary production with photosynthesis.
How does the US use biomass?
In the U.S., biomass today provides about 3-4% of primary energy. Biomass is used for heating wood stoves, cooking, transportation, and for electris power production.
How are biomass and alcohol production related to energy from the Sun?
Biomass production involves plants using photosynthesis to convert sunlight into energy stored in plant matter. This biomass can then be used as a feedstock for alcohol production, where microorganisms ferment the sugars in the biomass to produce ethanol. So, both biomass and alcohol production ultimately rely on sunlight as their primary energy source.
How much biomass does the world use?
In the U.S., biomass today provides about 3-4% of primary energy. Biomass is used for heating wood stoves, cooking, transportation, and for electris power production.
How do you calculate the percentage biomass passed on from 1 from producers to primary consumers 2 from primary to secondary consumers 3 from secondary consumers to carnivores?
e.g. ORGANISM BIOMASS Grass 1000 Herbivores 300 Small Carnivores 28 Large Carnivores 6 1) from producer to primary = (300/1000)x100 2) from primary to secondary = (28/300)x100 3) from secondary to carnivores = (6/28)x100 Hope this helps :)

How is primary production measured and what methods are commonly used to quantify it?
Primary production is measured by quantifying the amount of organic matter produced by photosynthetic organisms in an ecosystem. Common methods used to quantify primary production include measuring oxygen production, carbon dioxide uptake, and biomass accumulation. These measurements help scientists understand the productivity and energy flow within an ecosystem.
How is primary productivity measured in an ecosystem?
Primary productivity in an ecosystem is typically measured by calculating the amount of energy or biomass produced by plants through photosynthesis. This can be done by measuring the rate of oxygen production, tracking the growth of plant biomass, or using remote sensing techniques to estimate plant productivity.
Would the biomass of a tertiary consumer be larger or smaller than the biomass of a primary consumer?
The biomass of a tertiary consumer would be smaller than the biomass of a primary consumer. This is because energy is lost as it moves up the food chain through each trophic level. Tertiary consumers have less available energy and biomass compared to primary consumers.
How is primary productively related to biomass?
Producers store chemical energy in the biomass, also known as organic material, and the rate by which producers in an ecosystem build biomass is primary productivity. Both dealing with building biomass by the action caused by producers. Hope this helps (:
What is Gross primary production?
The rate at which an ecosystems producers covert solar energy into chemical energy (in the form of biomass). To Solve : GPP = NPP + R (R - Respiration)
What are the broad categories of aquatic biomass?
The broad categories of aquatic biomass are primary producers and secondary producers.
