tertiary
Third trophic level. It eats insects.
Well, I am guesing either the secondary of third trophic level. If you know the trophic level of clams and shellfish, the walrus is right above that.
Yes, a spider is typically considered to be a secondary consumer and therefore would be at the third trophic level in a food chain. Spiders feed on primary consumers such as insects, which are at the second trophic level.
the third level.
The trophic level is the level in the food chain that an animal occupies. The armadillo belongs to both the second and third trophic levels.
A snake is an organism that is a third-order heterotroph. Snakes belong to the third trophic level. There are approximately 3,000 species of snakes.
Secondary consumers belong on the 2nd level trophic level yah!
The third trophic level is called Tertiary.

If the first trophic level has 300,000 kilocalories and there is a 90 percent loss of energy between trophic levels, then only 10 percent of the energy is passed on to the next level. Therefore, the second trophic level would have 30,000 kilocalories (10% of 300,000). Applying the same loss rate, the third trophic level would have 3,000 kilocalories (10% of 30,000).
The lowest level of the energy pyramid that contains carnivores is the third trophic level. These carnivores consume herbivores from the second trophic level that feed on producers at the first trophic level.
