    Tropical level in an ecosystem:<b style=”background-color: var(–bb-content-background-color); font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>

    Trophic level is a step in a nutritive series, or food chain, of a an ecosystem. The organisms in the food chain are classified into these levels based on their feeding behavior.

    producers include plants:

    The first trophic level includes herbivores like a cow, goat, etc.

    The second trophic level includes carnivores like a tiger, lion ,etc.

    The tertiary trophic level includes omnivores like humans, bears, etc.,.

    The trophic level of an organism is the position that it occupies in a food web.

    A food chain is a succession or organisms or a stepwise process where organisms eat others and can, in turn , be eaten.

    The trophic level of an organism is the number of steps it is from the start of the chain.

    A food web starts at trophic level 1 with primary producers such as plant, then to herbivores at level 2 carnivores at level 3, and higher, and apex predator’s at leverl 4 or 5.

    Producers are autotrophs which includes plants or algae

    Plants and algae do not usually eat other organisms, but pull nutrients and manufacture their food using photosynthesis.

    They are called primary producers . The energy from the sun powers the base of the food chain.

    Consumer are species that cannot manufacture their food and need to consume other organisms. Animals that consume primary producers like plants are called herbivores.

    EXAMPLE

    Gross grasshopper frog snake eagle

    The grass is the producer in the trophic level. Grasshopper is the consumer or also called herbivores. The frog is the 1st level carnivore Snake is the 2nd level carnivore. Eagle is the 3rd level carnivores.
