Algae and green plants are first in what food chain?

Algae and green plants are primary producers in the food chain, forming the base of many aquatic and terrestrial ecosystems. They convert sunlight into energy through photosynthesis, serving as a crucial energy source for consumers higher up in the food chain.


What is the difference between terrestrial biome and aquatic biome?

Differences between Terrestrial and Aquatic systemsbecause aquatic environments are so rich in nutrients they support more live than equivalent terrestrial ecosystems. The small drifting photosynthetic organisms of the oceans, referred to collectively as phytoplankton are regarded as the major photosynthesizers, or primary producers, of the earth,aquatic environments are much more stable than terrestrial environments, with smaller fluctuations in temperature and other variables,aquatic organisms are seldom exposed to desiccationwhile terrestrial organisms are often exposed to desiccation and are usually relatively resistant to drying out,oxygen (because there is very much less present) is sometimes a limiting factor an aquatic habitats but this is seldom the case in terrestrial habitats,light can be a limiting factor in some aquatic habitats, but in most terrestrial environments there is hardly ever a a shortage of light,terrestrial animals are influenced far more by gravity, while water supports aquatic organisms.


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.


What is the primary objection to agricultural biotechnology?

One primary objection to agricultural biotechnology is concerns over the potential health and environmental risks associated with genetically modified organisms (GMOs). Critics argue that GMOs may have unintended consequences on ecosystems and human health, and there are also worries about corporate control over seed production and the impact on small farmers.


How are food webs on land and in the water different?

Food webs on land typically have a more complex structure with more levels of consumers compared to those in water. On land, primary producers are mostly plants, while in water, phytoplankton are a major source of primary production. Additionally, terrestrial food webs have more diverse animal species due to the higher availability of resources on land.

How is primary productivity limited by water?

Primary productivity can be limited by water availability in terrestrial ecosystems, as water is needed for photosynthesis to occur. In aquatic ecosystems, primary productivity can also be limited by water availability, as light penetration can be reduced in murky waters, limiting the amount of photosynthesis that can take place. Additionally, drought conditions can directly reduce primary productivity in both terrestrial and aquatic ecosystems.


What are the similarities and differences between the aquatic trophic pyramid and the terrestrial trophic pyramid?

Similarities: Both aquatic and terrestrial trophic pyramids show the flow of energy through different trophic levels, with primary producers at the base and top predators at the apex. Differences: Aquatic trophic pyramids tend to have more biomass at lower trophic levels due to the higher productivity of aquatic ecosystems, while terrestrial trophic pyramids typically have a larger biomass at higher trophic levels. Additionally, primary producers in aquatic ecosystems are often phytoplankton, while in terrestrial ecosystems they are mostly plants.


The organisms that are classified as primary consumers are the?

organisms that feed on producers and are typically herbivores, consuming plants or algae as their main food source. Examples include rabbits, deer, and grasshoppers in terrestrial ecosystems, and zooplankton in aquatic ecosystems.


Rank these ecosystems from lowest to highest primary productivity open ocean tropical rainforest desert lake?

Desert < Open ocean < Lake < Tropical rainforest. Desert ecosystems have the lowest primary productivity due to low water availability and extreme conditions. Open ocean ecosystems are next due to limited nutrients. Lake ecosystems have higher productivity as they are more nutrient-rich. Tropical rainforests have the highest productivity due to the abundance of sunlight, water, and nutrients.


How does the amount of light affect primary production?

The amount of light affects primary production by influencing the rate at which photosynthesis occurs in plants and algae. More light typically leads to higher rates of photosynthesis and therefore increased primary production in ecosystems. However, excessive light can also be detrimental by causing damage to photosynthetic machinery.


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)


The rate at which new organic material is made available to consumers equals the what primary production?

It is the gross primary production - net primary production


What was the Production Budget for Primary Colors?

The Production Budget for Primary Colors was $65,000,000.


What is the primary product in primary production?

it refers to raw meterials we used in production process


What is the difference between GPP and NPP?

Gross primary production (GPP) is the rate at which an ecosystem's producers capture and store a given amount of chemical energy as biomass in a given length of time. Some fraction of this fixed energy is used by primary producers for cellular respiration and maintenance of existing tissues (i.e., "growth respiration" and "maintenance respiration").[1] The remaining fixed energy (i.e., mass of photosynthate) is referred to as net primary production (NPP).NPP = GPP - respiration [by plants]Net primary production is the rate at which all the plants in an ecosystem produce net useful chemical energy; it is equal to the difference between the rate at which the plants in an ecosystem produce useful chemical energy (GPP) and the rate at which they use some of that energy during respiration. Some net primary production goes toward growth and reproduction of primary producers, while some is consumed by herbivores.Both gross and net primary production are in units of mass / area / time. In terrestrial ecosystems, mass of carbon per unit area per year (g C/m2/yr) is most often used as the unit of measurement.

What trophic level contains the greatest biomass in most ecosystems?

The trophic level that typically contains the greatest biomass in most ecosystems is the primary producers, also known as autotrophs. These organisms, such as plants and algae, convert sunlight into energy through photosynthesis, forming the base of the food chain. As energy is transferred up the trophic levels, biomass decreases due to energy loss through respiration and heat production. Therefore, primary producers have the highest biomass as they support the entire ecosystem's energy flow.
