Symbiosis
共生关系
Description
Understand symbiosis — close relationships between different species — including mutualism (both benefit, like clownfish and anemones), commensalism (one benefits without harming the other, like remora fish riding sharks), and parasitism (one benefits at the other's expense, like ticks on deer) — and recognise these relationships in nature
Mastery Evidence
- Defines symbiosis as a close relationship between different species
- Distinguishes mutualism, commensalism, and parasitism with an example of each
- Identifies symbiotic relationships when presented with new scenarios
Assessment Prompt
If your child sees a nature programme showing a small bird picking insects off a buffalo's back, can they explain that both animals benefit from this relationship and name the type of symbiosis?
