Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.</span>
For the availability of land
Answer:
The correct answer is A. A disadvantage of shade-grown coffee beans is that shade-grown coffee trees produce fewer coffee beans per plant.
Explanation:
The expression “shade coffee” designates coffee produced on trees cultivated under a canopy rather than in vast fields exposed to the sun, which in turn is a very productive technique but requires, for the maintenance of a high yield, the irrigation and spreading of large quantities of polluting pesticides and fertilizers. Rather, shade trees protect coffee trees from rain and sunlight, help preserve soil quality, reduce the amount of weed control needed, and provide habitat for a diverse range of wildlife. The organic matter produced by these trees also provides natural mulch which reduces the need for chemical fertilizers, prevents erosion and provides important nutrients to the soil. But the negative part of this type of coffee growing is that it produces a lesser amout of coffe beans.
They provide evidence that movements of the crust are a result of slow moving currents in the mantle. Since earthquakes and volcanic eruptions are usually a result of stick-slip movements between 2 more plates and it is tension changes that are responsible for this sudden movement, the plates must be moving overtime or this tension would remain fairly constant.
