The Sun (an abiotic factor) provides energy for producers ( a biotic factor) which use light energy to undergo the process of photosynthesis. When other consumers eat the producers they are receiving energy as well.
A sharp, stinging odor would most likely be a defense mechanism for a plant.
A Punnett square would help here.
Let's say (R) is dominant red and (r) is recessive red, aka yellow.
You start with F1 hybrid flowers that are all (Rr) - these are all <em>orange</em>. So when they reproduce, both parents are (Rr). When you create a Punnett square, you'll see that the results for the F2 generation are (RR), (rr), and (Rr) twice.
(RR) is red, (rr) is yellow, and (Rr) is orange, just like the F1 generation.
The correct answer to the question that is being presented above would be letter d. Both select for favorable traits in a species. The human's development of different dog breeds using the process of selective breeding is similar to evolution by natural selection through selecting for favorable traits in a species.<span>
