Why are producers so important
to ecosystems?
A. Producers are used to put water into the air of
dry places.
B. Producers help transfer energy from
secondary to tertiary consumers.
C. Producers capture energy and convert it for all
organisms to use.
Answer:
C
Explanation:
Producers are also known as autotrophs, which they make their own food. Producers capture sunlight energy and use it to convert CO2 (carbon dioxide) and H2O (water) into O2 (oxygen) and C6H12O6 (glucose) for other organisms to use. This process is called photosynthesis.
Why is DNA important?
It produces the energy a cell needs to survive.
lt is responsible for creating the food for photosynthesis.
It coordinates with the cell wall to determine what enters and leaves a cell.
It is what makes each type of living creature different.
Answer:
It is what makes each type of living creature different
Explanation:
DNA is basically our blueprint, how we were designed. It's almost impossible for someone's DNA to be exactly the same. Given the exclusion of twins, there is always going to be something different about creatures, even when it comes to doppelgangers!
Hope this helps!
DNA is important as it is what makes each type of living creature different. The correct option is D.
What is DNA?Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
Nucleotides are chemical building units that make up DNA. A phosphate group, a sugar group, and one of four different nitrogen bases make up these building components.
Nucleotides are joined together into chains, with the phosphate and sugar groups switching places, to create strands of DNA.
DNA is crucial for inheritance, protein coding, and supplying guidelines for life and its processes in all living organisms.
DNA controls a person's or an animal's growth, reproduction, and final demise. There are 46 chromosomes in total in each of a human cell's 23 pairs of chromosomes.
Thus, the correct option is D.

The pea aphid, a type of insect, contains light-capturing pigments in its exoskeleton. Scientists hypothesize the pea aphids gained the ability to synthesize these pigments from genes transferred from fungi during evolution. While pea phones do not have chloroplasts or fix carbon, researchers have found that pea aphids with more pigments have higher levels of ATP than those fewer pigments. Pea aphids also have been shown to increase production of ATP when exposed to sunlight.
Based on this information, is the pea aphid a true autotroph?
The pea aphid isn't a true autotroph because it is unable to use the energy from sunlight.
What is a true autotroph?A true autotroph is an organism that produces biomass by a chemical process called photosynthesis.
This type of autotroph generates biomass by means of photosynthetic cycles of production.
In conclusion, the pea aphid isn't a true autotroph because it is unable to use the energy from sunlight.
