2nd level cosumers are carnivres or omnivores that eat 1st level consumers.
A 2nd level consumer is an organism that primarily feeds on 1st level consumers (herbivores) in an ecological food chain. These organisms are also known as primary carnivores and play an important role in controlling the population of herbivores in an ecosystem.
An animal that eats 2nd level consumers. the 3rd level consumers are animals that mostly eat 2nd level consumers.
A 4th order cosumer is the consumer that feeds of third level consumers (kindof a no-brainer answer). 3rd order consumers feed of 2nd order cosumers and 2nd order consumers feed off 1st order consumers and 1st order consumers feed off producers like grass or bushes; plants that make their own energy from the sun... hope this answer is good enough.
there are multiple selections (over 10 combinations)
1st level consumers are any heterotrophs (animals that do not harvest food through photosynthesis or chemosynthesis) that eat producers (plants, bacteria, things that make their own food). 2nd level consumers are carnivores or omnivores that eat 1st level consumers, and the 3rd eats 2nd, and so on and so forth. Well a 3rd level consumer is a decomposer second is a carnivore first is a herbivore
Consumers can be classified into four levels: basic consumers who purchase goods and services for personal use, selective consumers who compare products and value quality, habitual consumers who have brand loyalty, and complex consumers who evaluate multiple factors before making a purchase decision.
Secondary consumers belong on the 2nd level trophic level yah!
Stonefly nymphs are generally carnivorous. They are typically 2nd or 3rd level consumers as they enjoy eating other animals like caddis flies, mayflies, and true flies. Stonefly nymphs may eat detritus or plants when they are particularly hungry at which point they would be 1st level consumers.
BIOACCUMULATION
No, 2nd consumers are carnivores
It is the 2nd consumer on the trophic level! :)
