Between which two components of ecosystems do materials cycle?
Between biotic (living) and abiotic (non-living) components.
Why is the recycling of materials important for future organisms?
It makes materials available as resources and building blocks.
Which microorganisms decompose dead organisms and waste?
Microorganisms such as bacteria and fungi.
What do microorganisms release into the soil as they decompose dead organisms and waste?
Mineral ions.
How do decomposing microorganisms return carbon to the atmosphere?
They release carbon dioxide through respiration.
How do plants use mineral ions from the soil?
They absorb them and use them for growth.
How can materials in plants pass to other organisms?
Through feeding.
What does the carbon cycle transfer, and between what?
It transfers carbon between organisms and the non-living environment.
What happens to atmospheric carbon dioxide during photosynthesis in plants?
Plants take it in and use its carbon to make organic substances.
How does carbon pass from plants to other organisms, and what does it provide?
It passes through feeding, providing material for growth.
How does respiration return carbon to the atmosphere?
Organisms release carbon as carbon dioxide during respiration.
What role do decomposer microorganisms play in the carbon cycle?
They break down dead organisms and waste, releasing carbon dioxide through respiration.
