Question

List four processes associated with Carbon cycle. State one effect of deforestation and one of afforestation on Carbon cycle.

Answer 1

Answer:

Increasing atmospheric CO2 is having detrimental effects on the Earth system. Societies have recognized that anthropogenic CO2 release must be rapidly reduced to avoid potentially catastrophic impacts. Achieving this via emissions reductions alone will be very difficult. Carbon dioxide removal (CDR) has been suggested to complement and compensate for insufficient emissions reductions, through increasing natural carbon sinks, engineering new carbon sinks, or combining natural uptake with engineered storage. Here, we review the carbon cycle responses to different CDR approaches and highlight the often-overlooked interaction and feedbacks between carbon reservoirs that ultimately determines CDR efficacy

Answer 2

Answer:

Processes in the carbon cycle :

1.___Carbon enters the atmosphere as carbon dioxide from respiration and combustion.

2.___Carbon dioxide is absorbed by producers to make glucose in photosynthesis.

3.___Animals feed on the plant passing the

carbon compounds along the food chain.

# Effect one of deforestation & afforestation on carbon cycle :--

* Deforestation :- Trees and forest balance the amount of Carbon in the atmosphere through the process of photosynthesis in which plants make their own food with carbon dioxide.

* Afforestation :- The rate of carbon storage in forest biomass depends on tree growth rate: the more biomass is added through photosynthesis the more carbon is stored.
