Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic material, returning nutrients to the soil and helping to recycle matter in the ecosystem.

Front

What is gravitropism?

Back

Gravitropism is a plant's growth response to gravity, where roots grow downward and stems grow upward.

Front

What is phototropism?

Back

Phototropism is a plant's growth response to light, where plants grow towards the light source.

Front

What is the difference between a herbivore and an omnivore?

Back

A herbivore only eats plants, while an omnivore eats both plants and animals.

Front

What is the significance of a volcanic eruption in ecological terms?

Back

A volcanic eruption can lead to primary succession by creating new land, but it can also cause secondary succession if it disturbs an existing community without removing the soil.
