Both of those two independent methods of investigation resulted in the same pattern which means it is significant.
Fossil records explain the history and evolution of life based on fossils. Fossils are remains of organisms preserved in sedimentary rock. In fossil records they are analyzed and arranged chronologically and in taxonomic order, so that can represent the evolution.
Phylogenies describes the relationships between organisms (species): from which organisms it is evolved, to which species it is most closely related etc.
It is used to organize living organisms into specific categories.
Answer:
An oceanographer study the ocean.
Explanation:
Answer:
(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
Explanation:
<em>(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
</em>
<em>(b) X: Decomposers return carbon to the soil and release waste. Y: Producers undergo photosynthesis.
</em>
<em>(c) X: Decomposers take in carbon dioxide. Y: Producers absorb carbon through their roots.
</em>
<em>(d)X: Producers absorb carbon through their roots. Y: Decomposers take in carbon dioxide.
</em>
<u>Box 2 (X) would be the process through which producers fix carbon dioxide to produce their own food, the carbohydrate. T</u>he process is otherwise known as photosynthesis and can be represented by the following equation:

<u>Box 4 (Y) would be the process of decomposition.</u> 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).
