There are four trophic levels in an ecological pyramid. They are primary producers, primary consumers, secondary consumers, and tertiary consumers.
The first trophic level, which are the producers
Primary producers are the bottom most trophic level.
Decomposers are last in food chains, so they can be 4th or 5th trophic level depending upon the food chain or food web:-producers-primary consumers-secondary consumers-ter. or quatr. and so on consumers-decomposers
Producers :-)
decomposers and producers.
Decomposers will break down dead animals and plants leaving free the nutrients or minerals necessary for plants to grow.

No, the tiger is a consumer, a secondary consumer in the food chain. Composer is not a trophic position on a food chain. Organisms are either producers, consumers or decomposers.
Producers aren't really a trophic level because they are producers. A trophic pyramid consists of consumers and the levels of energy between them. Since producers don't actually eat anything they are on the bottom.
Food webs are made from many food chains. A trophic level in every food chain is a stage where energy is transferred from a lower level to the next higher level. Trophic levels include producers, consumers (primary and secondary), decomposers.

Primary producers are the bottom most trophic level.
Energy that is lost at each trophic level of an ecosystem is replenished by the producers. The producers get it from the sun.
primary biomass is lost the higher you ger in the trophic levels
