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.

Plants, algae, and bacteria occupy the first trophic level of an organism.
Plants, algae, and bacteria occupy the first trophic level of an organism.
Producers, such as plants and algae, are able to convert solar energy into chemical energy through photosynthesis. They occupy the first trophic level in a food chain or food web.
In science it is explaned as a group of organisms that occupy the same position in a food chain. Each organism could be called a trophy of that level.
Humans occupy the highest trophic level in an ecological pyramid, known as the tertiary consumers. This means they are at the top of the food chain and primarily feed on organisms from lower trophic levels.
Mammals are a very broad group. Different mammals occupy different levels in the food chain including primary, secondary, and tertiary consumers as well as scavengers.
In an ecosystem energy passes from one feeding level to another. Producers are plants that occupy the first level in the ecosystem. They are the only organisms that can convert the sun's energy into chemical energy through photosynthesis. When plants are consumed, energy is passed on the herbivores and then carnivores. Without producers in the food chain there would be no energy produced for other consumers of the food chain, which is vital to daily life.
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.
An organism's position in the sequence of energy transfer in a food chain is determined by its trophic level. Producers, like plants, occupy the first trophic level, followed by primary consumers (herbivores), secondary consumers (carnivores), and so on. The flow of energy usually moves from lower to higher trophic levels.
