Then, we have started a new one: Ecosystems. We have learnt some new words and concepts such as ecosystems, habitad, food chain ... Here I have some of them because I took notes:
- Habitat: where an organism lives. Characterized by climate and weather, availability of food, water, other resources. It can be a small area or a large one.
- Species: single type of organisms that can be interbreed and produce fertile offspring.
- Population: individuals of a single species that occur together at a given place and time.
- Community: all the populations living together in the same area.
- Ecosystem: all the living things in a community and the physical and chemical factors that they interact with. Ecosystems are made up of the living creatures and the non-living thing that those creatures need within an area.
- Biotic factors: light, oxygen, water, carbon, dioxide, soil, nitrogen, nutrients, living space, temperature range...
- Energy moves through an ecosystem in one direction.
- Nutrients cycle through different parts of the ecosystem and can enter or leave it.
And also, we focus on Photosynthesis and respiration.
