Karforsyning

Karforsyning refers to the supply of carbon to an organism or ecosystem. In the context of plants, it relates to the availability of carbon dioxide, a key ingredient for photosynthesis. Plants take in carbon dioxide from the atmosphere through their stomata. The rate of photosynthesis, and therefore plant growth, can be influenced by the concentration of carbon dioxide available. In aquatic environments, dissolved carbon dioxide is the primary carbon source for photosynthetic organisms like algae and phytoplankton.

Beyond photosynthesis, karforsyning is also relevant in the context of cellular respiration, where organic carbon compounds are broken down to release energy. This process is fundamental to life for most organisms. In ecosystems, the cycling of carbon, including its supply to various trophic levels, is a crucial aspect of biogeochemical processes. Detritivores and decomposers play a vital role in breaking down organic matter, releasing carbon compounds that can then be utilized by other organisms. The availability of carbon, therefore, underpins the productivity and functioning of entire ecosystems. Fluctuations in carbon availability can have significant ecological consequences.
