Which best explains how insects help flowering plants in reproduction?
Question 9 options:
Insects help keep predators, like birds, away from flowers' seeds
Insects store food in flowers, providing nutrients flowers need to make seeds.
Crawling insects cause pollen to fall on the ground beneath flowering plants.
As they fly, insects spread pollen that sticks to their bodies from the flowers.

Question 11 options:
The roots of the fungus can absorb nutrients from the soil.
The hyphae, or feeding structures, reach deep into the wood to obtain nutrients.
The white cap of the fungus traps small insects and other organisms as they pass by.
The cap of the fungus can absorb chemicals from the air, like carbon and oxygen, and use the gases to make food.
