Is sea weed a primary consumer in the food chain?

Answer 1

Birds attack smaller crabs, sometimes carrying them high into the air and then dropping them on boulders to crack their shells. Fish with powerful, shell-crunching jaws also eat crabs. Many kinds of mammals, from seals to raccoons, also look forward to a crab dinner. What does a crab eat? Crabs eat small bits of plant and animal material that they find in the water and along the shoreline. This makes them primary consumers or herbivores and decomposers.

Answer 2

No a seal is not a primary consumer

Answer 3

No they are not because they are not herbivores. They typically eat fish, shrimp, isopods, amphipods and plankton.

Answer 4

They are both primary consumers (they have symbiotic plants in themselves) and secondary consumers because they also feed on plankton which may be plant or animal.

Answer 5

Yes it is.
