Bees fly to flower to flower gathering nectar, which they make into food benefiting the bees.
The niche of grasshopper would include the plant species it eats.
Explanation:
The niche of an organism is different to that of a habitat. A niche includes the interaction between organisms and the food that they eat, whereas, a habitat is a place where organisms are provided with food, protection and shelter.
Habitat is a place of ecosystem that involves other environmental factors like- rain, sunlight, humidity etc. So, food type eaten by grasshopper would be the description of a niche and not a habitat.
Answer:
Because natural selection selects for it. Thus it persists.
Explanation:
You have to understand heterozygote advantage. Basically, it's where heterozygotes have an advantage over homozygotes. In the case of sickle cell disease, heterozygotes have an advantage, and natural selection favors whatever is advantageous. Thus, because heterozygotes each have one recessive sickle-cell allele, as natural selection favors the heterozygotes, the recessive sickle-cell allele persists and remains in the gene pool.
