What model shows the number of organisms at each tropic level in an ecosystem?

The major types of ecological pyramids are a pyramid of numbers or biomass or energy.
The pyramid of numbers depicts the number of individual organisms at different trophic levels of food chain. Successive links of trophic structure decrease rapidly in number until there are very few carnivores at the top.
In many ecological pyramids, the producers form the base and the successive trophic levels make up the apex. The apex is a term meaning pointed top.
Energy pyramids are always slopping because less energy is transferred from each level than was paid into it.

What tropic level provides nourishment for the most organisms in the ecosystem?
a. primary consumersb. secondary consumersc. producersd. decomposers
What are organisms in the lowest trophic level of an ecosystem?
Plants are in the lowest trophic level of an ecosystem. Their level is the lowest because the needs of plants are the least complex compared to the other organisms present in an ecosystem.
What is the primary source of energy for all the organisms in the ecosystem represented below?
The trophic level that contains the organisms that are the source of all chemical energy used in an ecosystem is called the producer level. This level contains the organisms that can make their own food.
What trophic level would an autotrophic organisms occupied?
primary producer
Which group of organisms has the least biomass?
A tropic level is the position that an organism occupies in the food chain. The trophic level that has the least biomass is trophic level 5, which is composed of apex predators.
What group of organisms occupies the first tropic level of ecosystem?
Plants, algae, and bacteria occupy the first trophic level of an organism.
What tropic level provides nourishment for the most organisms in the ecosystem?
a. primary consumersb. secondary consumersc. producersd. decomposers
What does a number pyramid tell you about an ecosystem?
Shows the relative number of individual organisms at each trophic level.
What are organisms in the lowest trophic level of an ecosystem?
Plants are in the lowest trophic level of an ecosystem. Their level is the lowest because the needs of plants are the least complex compared to the other organisms present in an ecosystem.
What does it mean if an ecosystem is balanced?
- The organisms have to fit into the energy pyramid- The largest number of organism in any ecosystem needs to be the producers- The smallest number of organism need to be the highest level of consumers in that ecosystem
Why is there a decreasing number of organisms in each feeding level of the ecosystem?
Because there is less energy available at each feeding level, there is a limit to how many organisms can be a part of each progressive level.
An organism positioned in the sequence of energy transfered in an ecosystem is known as its?
tropic level
What organisms belongs to more than one tropic level?
Humans
What tropic level would an autotrophic organisms occupy?
Primary producer
Which level of organisms includes living and nonliving things?
Ecosystem
What group of organisms the second trophic level of an ecosystem?
The group of organisms that occupy the second trophic level of an ecosystem is the herbivores. The herbivores eat the plants in the first trophic level and are then called primary consumers. -Gallo :)
What group of organisms occupies the first trophies level of an ecosystem?
The secondary consumers (herbivores) occupie s the first trophies level of an ecosystem
