Thus, green plants (producers) occupy the first trophic level, herbivores, the second level (primary consumers), primary carnivores, the third level, and secondary carnivores, the fourth level (tertiary consumers). This trophic classification is of function and not of species as such. A given population of a species can occupy more than one trophic level, according to the source of assimilated energy. (Adapted from ODUM, E.P. Ecology, Rio de Janeiro: Guanabara Koogan, 2012, p. 85). As part of the environment, humans, when feeding, can occupy from the primary consumer level to the last consumer level. Based on the food web represented below, select the alternative that presents the trophic levels occupied by humans:
a.
primary consumer, secondary consumer, tertiary consumer.
b.
producer, primary consumer, tertiary consumer, decomposer.
c.
primary consumer, secondary consumer, tertiary consumer, decomposer.
d.
producer, primary consumer, secondary consumer, tertiary consumer.
e.
primary consumer, secondary consumer, tertiary consumer, quaternary consumer.

The excreta produced by animals also help maintain environmental health as they serve as a source of nutrients for other living beings present in the animal's environment, thus contributing to the naturally established food chain in that ecosystem. What is the main function of these excreta in this context?

The tissues of the human body perform specific functions and are organized into systems that ensure the organism's homeostasis. Imagine that a scientist, while studying the effects of a disease that affects skeletal muscle tissue, observed that, as a result of the disease, the contraction capacity of the muscle fibers was compromised. Based on this situation, describe: 1) The relationship between the structure of muscle fibers and their contractile function, including the main cellular components involved in this process. 2) Explain how a change in a tissue such as skeletal muscle can affect the functioning of other systems in the human body, considering the interdependence between tissues and systems for the maintenance of health.
