What is a trophic level and what determines an organism's trophic level?
Trophic level is a group of organisms that occupy the same position in a food chain. An organisms trophic level is determined by its position in a food chain against all levels Producers(Level 1), Herbivores(Level 2), Predators(Level 3), and Carnivores as Level 4 or 5.
The percentage of energy in one trophic level that transfers to the next level in the average ecosystem is?
Studies of a variety of communities indicate that the net transfer of energy between tropic levels is roughly 10% efficient, although transfer among levels within different communities varies significantly.
What is the average level for a key stage 3 sats paper?
If you get a level 3-4 then you are under- achievingIf you get a level 5 (ideally a high one) then you are average and on track for a C at GCSE.If you get a level 6 then you are a bit higher than average and on track for a C or B at GCSE.If you get a level 7 then you are a lot higher than average and on track for an A or B (even perhaps an A* if you work hard).If you get a level 8 then you are doing exceptionally well and you would be on track for an A* at GCSE level.Hope this helped :)
What is an indicator of one's social position?
One indicator of social position is one's occupation or job title, as it often reflects one's level of education, income, and societal status. Another indicator is one's level of education, as higher levels of education are often associated with higher social positions. Additionally, one's network of relationships and social connections can also be indicative of their social position.
What percentage of Americans make over 170K?
Approximately 10% of Americans make over $170,000 annually. This income level represents a smaller portion of the population, indicating higher earning potential.
At what trophic level does the organism in question reside?
The organism resides at the primary consumer trophic level.
What happens as you move down a trophic level?
As you move down a trophic level in a food chain or food web, energy is transferred from one organism to another. With each step down, energy is lost through metabolism and heat production, resulting in less energy being available for the next trophic level. This is why organisms at higher trophic levels typically have fewer individuals compared to lower trophic levels.
What is an organism's relative position in a sequence of energy transfers in a food chain or food pyramid?
An organism's relative position in a sequence of energy transfers in a food chain or food pyramid is determined by its trophic level. Producers occupy the first trophic level, followed by primary consumers, secondary consumers, and so on, with decomposers at the end. Energy is transferred from one trophic level to the next as organisms are consumed by those at higher trophic levels.
What indicates the organism's position in the sequence of energy transfers?
An organism's trophic level in an ecosystem indicates its position in the sequence of energy transfers. Producers are at the bottom, followed by primary consumers, secondary consumers, and so on. The higher the trophic level, the further the organism is from the original energy source.
What is the trophic level of the bird?
The trophic level is where an organism falls on the food chain. Most birds fall on the highest level, trophic level 4.
What is a trophic level and what determines an organism's trophic level?
Trophic level is a group of organisms that occupy the same position in a food chain. An organisms trophic level is determined by its position in a food chain against all levels Producers(Level 1), Herbivores(Level 2), Predators(Level 3), and Carnivores as Level 4 or 5.
Which organism is at the higher trophic level - dolphins or plankton?
Dolphins are at a higher trophic level than plankton. Dolphins are consumers that feed on other organisms, while plankton are primary producers that form the base of the marine food chain.
Which organism is a third-order heterotroph to what trophic level does that organism belong?
A snake is an organism that is a third-order heterotroph. Snakes belong to the third trophic level. There are approximately 3,000 species of snakes.
What is the relationship between the trophic level of an organism and the concentration of DDT in its body?
If an animal on a high trophic level eats other organisms on a lower trophic level effected by DDT, the animals level will be affected.
Do the biomass of organisms in a typical ecological pyramid increases at each level?
The biomass of each organism decreases with each level. With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level.
Which type of organisms are in the first trophic level?
Plants, algae, and bacteria occupy the first trophic level of an organism.
What do the organism in each tropic level eat?
1st trophic level=flowers,trees,grass & algae. 2nd trophic level=caterpillars,cow,grasshoppers & bettes. 3rd trophic level=humans,birds & frogs 4th trophic level=lions,dogs and snakes
