Primary producers-- these are the plants and other producers that create their own energy via sunlight or other means. Consumers ingest these plants, placing them at the second level of a trophic pyramid.

Which type of organisms are in the first trophic level?
Plants, algae, and bacteria occupy the first trophic level of an organism.
What animal would be at the 2nd trophic level?
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 :)
In the photosynthesis process what trophic level occur?
Photosynthetic organisms make up the producer trophic level.
What does a number pyramid tell you about an ecosystem?
Shows the relative number of individual organisms at each trophic level.
Approximately what percentage of organic energy gets transferred from organisms on one trophic level to the next trophic level?
ten percent
What is the lowest trophic level?
The first trophic level is a primary producer. The main purpose of these organisms is to produce things for other organisms to use.
Organisms at the first trophic level are called?
Producers make up the first trophic level. A trophic level is each step in a food chain or food web is called 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 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 is the crickets trophic level?
Crickets are a first order consumer. This means that they consume the organisms at the lowest trophic level which is the producers.
In a food web what organism make up the first trophic level?
The first trophic level ofof a food web is almost always made of autotrophic organisms.
What animal would be at the 2nd trophic level?
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 is a trophic level and what determines an organism's trophic level?
A trophic level is the position an organism occupies in a food chain. It is determined by the organism's source of energy and nutrients. Primary producers occupy the first trophic level, herbivores occupy the second trophic level, and so on up the food chain.
What group of organisms occupies the first tropic level of ecosystem?
Plants, algae, and bacteria occupy the first trophic level of an organism.
In the photosynthesis process what trophic level occur?
Photosynthetic organisms make up the producer trophic level.
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.
