Enunciat
The function of nutrition comprises all the processes involved in obtaining substances from the environment and transforming them into substances of our own or decomposing them to obtain energy.
In 1962, the writer and marine biologist Rachel Carson published The Silent Spring, an investigation into the widespread use of pesticides, in which she denounced that the poisons used were accumulating in the food chain, with enormous risks to human health and terrible effects on flora and fauna.
QUESTIONS:
In the following activity we will work on the function of nutrition.
a) Explain what the two types of nutrition consist of and indicate the groups of living beings that present each one of them.
b) Indicate if the following living beings are autotrophic or heterotrophic: snail, oak, robin, seaweed, gecko, magnolia, mushroom and oleander.
c) Why is it said that autotrophic and heterotrophic organisms depend on each other?
d) The image shows us how some living beings feed from others, a food chain, for example, in a cultivated field. As Rachel Carson says in her book, the pesticides we use accumulate along this chain. Why do you think she titled it "Silent Spring"?
Observacions i context
Precursors of Rachel Carson were the conservationist Beatrix Potter and the nature photographer, writer and ecologist Jane Stratton-Porter. Shirley Briggs, in addition to being an ornithologist and naturalist, collaborated in her work as a photographer.
Scientist Theo Colborn continued to research and publish on toxic chemicals extending Rachel Carson's legacy. Frances Oldham Kelsey, a contemporary and connoisseur of the author's work, devoted herself to pharmacological medicine and prevented the use of thalidomide in the USA, which prevented the tragedy that occurred in other countries.
In 1974, Françoise d'Eaubonne coined the term "ecofeminism" in her work Feminism or Death, where she affirmed the need to rethink the relationship with nature from new parameters.
The ecological movements that emerged after the author's death are a continuation of her legacy of environmental awareness. We can also relate her to environmental activists such as Yayo Herrero, Vandana Shiva, Berta Cáceres, Sunita Narain or Greta Thunberg.
Descripció
In this activity we work on nutrition as one of the three vital functions. It consists of three questions: first, the two types of nutrition must be defined; then, we must say what type of nutrition different organisms have and, finally, we must see the trophic relationship between all living beings.
These questions are framed within the biodiversity of the planet and the different relationships that are established between living beings.
