Question

A mycologist working with public health officials investigates fungal diseases in immunocompromised patients while also studying how fungi help forest ecosystems recycle nutrients. Which four statements reveal fungal ecological and health roles?
Question 8 options:

Fungi serve essential decomposer roles in ecosystems

Some fungi can cause infections in vulnerable individuals

The same organism group can have both beneficial and harmful effects

Immune system status affects fungal infection risk

All fungi are equally dangerous to human health

Fungal ecosystem functions are separate from health effects

Answer 1

- Fungi serve essential decomposer roles in ecosystems — they break down dead organic matter and recycle nutrients.
- Some fungi can cause infections in vulnerable individuals — certain species are opportunistic pathogens.
- The same organism group can have both beneficial and harmful effects — fungi can be mutualists (e.g., mycorrhizae) and pathogens.
- Immune system status affects fungal infection risk — immunocompromised people are more susceptible to fungal disease.
