Describe a meal in which a person would be feeding at two or more trophic levels and identify the levels?
If a person were eating meat and vegetables, he/she would be feeding as a first order consumer (vegetables) and a second order consumer (meat).
What is trophic mass?
I would assume it to be the amount of mass in a specific trophic level. Thus, the trophic mass pyramid.
Is a spider a the third trophic level?
Yes. Plants would be the first trophic level, insects that eat the plants would be the second, and the spiders that eat the insects would be the third.
What trophic level is the bat in?
A vampire bat would most likely be on the top trophic level. This level would be tertiary consumers and is because vampire bats don't have any predators.
What would happen biologically if humans changed their trophic level position?
At the moment humans can be at different trophic levels depending on what they eat. A vegetarian is at the second trophic level as s/he eats only plants. Someone who ate only grazing animals would be at the third level. If you eat a carnivore such as a tuna fish you are at the fourth level. Most of us eat both plants and animals so we don't really have a level. That said, if we all moved to a specific diet there would probably be gradual genetic changes to favour our coping with that. We see some evidence of this in isolated groups with restricted diets today.
What trophic levels would cars be in?
The One We are in right now.
How would an ecosystem with a greater number of individual herbivores than individual producers affect the shape of the ecosystem's pyramid of numbers?
It expresses biomass at different trophic levels in an ecosystem.
What are the levels of trophic level?
i think it would be producer, then primary consumer, then secondary consumer, then tertiary consumer.
Does a cheetah belong in a trophic level?
i hope you mean trophic levels because then my answer will be correct. and yes it would be in the top level because producers go at the bottom and since a cheetah is a top consumer (nothing else eats it) it would go at the top.

What do you think would happen to consumers if they a re less plant growth?
A decrease in consumers, naturally, all the way up the trophic levels.
Why is the number of trophic level that can exist limited?
All sources of energy come from the sun. Autotrophs make their own energy through photosynthesis by collecting energy from the sun. When an organism (herbivore) at the next trophic level eats them they only get approximately 10% of the energy that the first organism had. When another organism eats the animal that ate the plate they only get approximately 10% of the energy of what that animal got from the previous animal. So this animal only got 1% of the energy from the sun. If more trophic levels existed they would only get 10% of this 1% so would not get enough energy (approximately 0.1%) so is why trophic levels are limited.
Why are there always fewer tertiary consumers than producers in an ecosystem?
Only 10% of energy is moved from one trophic level to another in the biomass consumed. So, at the tertiary level there is only enough food energy to support a limited number of consumers. As the number of trophic levels increases, you also have to be more adapted so you can become a predator of the trophic levels below you. If for example there was a species that were above humans, they would have to be smarter, quicker and more adapted - which gets progressively harder.
Why do biologists measure the number of trophies levels in an ecosystem measure the number of trophic levels in an ecosystem?
To check its stability and health
If decomposers were added to an energy pyramid that contains producers primary consumers and secondary consumers which trophic level or levels would be affected?
all consumers
What is trophic mass?
I would assume it to be the amount of mass in a specific trophic level. Thus, the trophic mass pyramid.
Does the population size increase or decrease at higher trophic levels in the pyramid of numbers of an ecosystem consisting of a tree insects (that are herbivores) and birds feeding on the insects?
Population sizes decrease at higher trophic levels. If they increased the insects population would decrease meaning there would be less food available for the birds so their population size would then decrease. Look at the relationships between predator and prey species for more information
