This document discusses the biosphere and includes information about producers, consumers, food chains, food webs, and protecting biodiversity. It explains that plants and algae are producers that make their own food through photosynthesis. It also outlines the different types of consumers - primary, secondary, and tertiary - and their roles in food chains. Additionally, it notes that most living things are part of multiple interconnected food chains that make up a food web. The document closes by mentioning that extinction is a natural process but some species are endangered, so protected areas like national parks and biosphere reserves are created to protect wildlife.

3. Food chain
 Producers: Plants and algae are producers.The
made their own food through photosynthesis.
 Consumers: Primary: such as rabbits and
grasshoppers, eat producers.
 Secundary: such as foxes and toads, are pedators
which eat primary consumers. Carnibores and
omnivores.
 Tertiary: such as snades and hawds, eat
secondary consumers.
 Descomposers: live on the remains of other
living thing.Most decomposers are fungi and
barteria.

4. Food web
 Most living things are part of more than one
food chain.There can be many different food
chains in an ecosystem.The connected food
chains make up a food web.

5. Extinction and Protecting
biodiversity
 Is often a natural process and has ocurred for
millions of years.
 Endangered species are those which are in
danger of extinction.
 National parks and biosphere reserces are
created to protect wildlife and its enviroment.
