Answer:
The first trophic level
Explanation:
The most important trophic level in the ecosystem is the the first trophic level. This trophic level is dominated by the plants the furnishes the ecosystem with food.
- The ecosystem is made up of living and non - living components.
- To being with, the trophic levels are the feeding levels which corresponds with the energy levels.
- Now, the most important of all is the first trophic level
- It is made up of plants which are called producers.
- They use inorganic matter to produce food for the whole ecosystem.
- This food is the source of energy for all living activities in the system.

Answer:
Natural Selection
Explanation:
In natural selection process of evolution, traits that are essential for an individual to be fit enough to survive under environmental stress become dominant.
Since the flowers are of blue or yellow color, it is essential for a bee to be able enough to perceive the blue and yellow color. Hence, the eyes of bee with time have evolved to perceive these two color so that they can pollinate flower.
Answer:
a sense organ
Explanation:
this is because sense organs are part of nervous system
Answer: No, mRNA ( messenger RNA) model does not closely resemble the DNA strand from which it is transcribed.
This is because mRNA strand is complementary to the strand of DNA template that is used in its synthesis during the process called transcription. The polarity of DNA template is 3' to 5' whereas that of mRNA transcribed is 5' to 3' that is both the strands have antiparallel polarity.
This is the reason template DNA is referred antisense. mRNA strand more closely resembles the sense strand ( which is complementary strand of DNA template in a double helix).
