The reason tropical deforestatio is worse than temperate deforestation is because there is
a. there is more carbon in the ground in temparate forests
b. more carbon in tress in temperate forests
c. rates of photosysnthesis are higher in temperate forests

Option A, there is more carbon in the ground in temparate forests

Explanation:

In temperate forests the nutrients are mostly found in the soil including the carbon, while in case of tropical forests these nutrients (including carbon) are up taken by the trees and stored there itself. Now when the tropical forest trees are cut down the carbon reserves with in the trees is  destroyed and released in the atmosphere. As per estimate the amount of carbon released by deforestation of tropical forest is much more disastrous than the gas emission of automobiles and industries in the current time.

Hence, option A is the correct choice of answer

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
