How do the benefits of natural change to ecosystems compare to the disadvantages?

antiseptic1488 [7]

The correct answer is:

b.The benefits outweigh the disadvantages.

Explanation:

Natural changes to the ecosystem transfer to the environmental phenomenon that occurs naturally. Natural changes hold floods, volcanic activity, hurricanes, dehydration, and earthquakes. They can be deadly, but they also have benefits.The benefit of the flood is, for example, contributing nutrients to the soil that were wanting. Also, there may be the relocation of fishes and organisms existing in water bodies, which develops the ecosystem.

leonid [27]

Answer:

(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.

Explanation:

(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.

(b) X: Decomposers return carbon to the soil and release waste. Y: Producers undergo photosynthesis.

(c) X: Decomposers take in carbon dioxide. Y: Producers absorb carbon through their roots.

(d)X: Producers absorb carbon through their roots. Y: Decomposers take in carbon dioxide.

Box 2 (X) would be the process through which producers fix carbon dioxide to produce their own food, the carbohydrate. The process is otherwise known as photosynthesis and can be represented by the following equation:

$6CO_2 + 6H_20 --> C_6H_1_2O_6 + 6O_2$

Box 4 (Y) would be the process of decomposition. Both producers and consumers eventually die and decompose in the soil. During this process, some of the carbon returns to the soil as organic matters while the process of microbial decomposition releases carbon dioxide into the atmosphere.

The correct option would be (a).
