Explanations: answer key for all 10 questions
- Q1: What is symbiosis?
Answer: A close long-term relationship between species
It can help, harm or have no effect.
- Q2: In mutualism, how do both partners fare?
Answer: Both benefit
Bees and flowers are an example.
- Q3: In commensalism, what happens?
Answer: One benefits and the other is unaffected
Barnacles on whales are an example.
- Q4: Which is an example of parasitism?
Answer: Tick on a dog
The tick benefits, the dog is harmed.
- Q5: How do clownfish and sea anemones help each other?
Answer: Clownfish get shelter; anemones get food and cleaning
Clownfish mucus protects them from stings.
- Q6: A lichen is a partnership between a fungus and what?
Answer: An alga or cyanobacterium
The fungus provides shelter; the partner makes food.
- Q7: What do mycorrhizal fungi do for plant roots?
Answer: Help absorb water and nutrients
Most land plants have them.
- Q8: What do cleaner wrasse fish do?
Answer: Eat parasites off larger fish
Big fish line up at cleaning stations.
- Q9: How do gut bacteria help humans?
Answer: They aid digestion and make vitamins
We host trillions of them.
- Q10: Cuckoos laying eggs in other birds' nests is called what?
Answer: Brood parasitism
Hosts raise the cuckoo chicks.
The Symbiosis Quiz – Living Together
Symbiosis describes close relationships between different species. In mutualism, both benefit, as when bees pollinate flowers while collecting nectar. In commensalism, one benefits without affecting the other, and in parasitism, one benefits at the other's expense.
Examples are everywhere. Clownfish shelter in sea anemones, lichens combine fungi and algae, oxpeckers eat ticks off large mammals and cleaner fish remove parasites from bigger fish. Most land plants rely on fungi in their roots.
Humans are part of symbiosis too. Trillions of gut bacteria help us digest food and train our immune systems. Understanding symbiosis helps scientists protect ecosystems and improve health and farming.
