What describes a possible cause of a negative carbon flux 1 point
in the atmosphere due to processes occurring in a forest
ecosystem? *

Deforestation

Explanation:

Deforestation is the indiscriminate or unplanned cutting down of trees. Due to deforestation, carbon dioxide increases in the atmosphere. This is due to release of carbon present in plants as CO2 through the action of saprophytes or combustion. An increase in atmospheric CO2 may lead to global warming because of the so-called greenhouse effect.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
