Question

Human activities that interfere with nutrient recycling and energy flow in terrestrial ecosystem

Answer 1

Answer:

HUMAN ACTIVITIES AND THEIR INFLUENCE ON NUTRIENT CYCLES

The earth’s sustainability is very much dependent on the maintaining of its state of equilibrium. This state of equilibrium also determines the functioning of the ecosystem, which is restored through nutrient cycles. In recent years, there has been an increasing awareness that human activities have affected the earth sustainability in one way or another. So how exactly do we affect this sustainability, and to what extent?

Human activities that are known to be environmentally unfriendly, such as deforestation and fossil fuel burning, have directly and indirectly changed the biogeochemical and physical processes which affects the earth’s climate. These modifications to the processes in the atmosphere affects and disturbs a variety of beneficial effects of the ecosystem. The beneficial effects of the ecosystem include helping to maintain relative climate stability, protecting the earth’s living organisms from the sun’s harmful ultraviolet radiation, mediating runoff and evapotranspiration, and regulating nutrient cycling.

Nutrient cycles always involve the achievement of equilibrium states, a balance in the cycling of the element between spheres. However, achieving these equilibrium states requires overall balance which usually involves elements being distributed on a global scale. Hence, a disruption in one cycle would result in the disruption in all other cycles. Below are some ways how human activities have contributed to the disruption of nutrient cycles.
