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).

Answer:(2010) analysed how individual components of the atmosphere contribute to the total greenhouse effect. They estimated that water vapor accounts for about 50% of Earth's greenhouse effect, with clouds contributing 25%, carbon dioxide 20%, and the minor greenhouse gases and aerosols accounting for the remaining 5%.

It is speeding up because more distance is covered every second.
Explanation:
The car can be described to be speeding up because more distance is covered every second. 
From what we understand about velocity and acceleration, the car is accelerating through the ramp. 
It's velocity is increasing with every second it covers. 
This will invariable reduce the time between each distance covered. 
Originally, the toy car starts with a low initial velocity or speed. As it gains acceleration, the speed will increase and more distance covered per seconds. 
This is why the dots clustered towards the end of the diagram. The positions are getting closer and distance reducing per seconds.

Answer:
a. True
Explanation:
Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).
