Numa cadeia trófico, a energia química armazenada nos compostos orgânicos de seus produtores é transferida para as demais componentes da cadeia. essa energia ao passar de um nível trofico para outro aumenta, diminui ou permanece?

Decreased

Ten percent energy rule

Food chain refers to a process cycle from producer to consumer to decomposer.
Plants – herbivores – omnivores – carnivores Start -> Plants -> herbivore insect -> spiders -> small bird -> Snake -> hawk -> fox -> lion -> when died the body will be eaten by hyena-> when hyena died -> body get decompose and be eaten  by worms and the rest will be plant’s fertilizer.

The process of the food chain will then again takes place over and over again.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
