Answer:
1)Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
2)Speciation is the process by which new species form.
3) It occurs when groups in a species become reproductively isolated and diverge.
Explanation:
<span>Sea breezes and land breezes are similar in that they are both created by changes in temperature near the ground. With a sea breeze, the air over land warms (during daytime), pressure drops, and air accelerates from sea to land in response. With a land breeze, the air over land cools (during nighttime), pressure rises, and air accelerates from land to sea in response.</span>
Definitely #2 is the answer
Answer:
Mutualism
Explanation:
Organisms in an ecosystem interact with one another from time to time. The close interaction between two organisms is referred to as SYMBIOSIS. Symbiosis is of different types depending on the how it affects the involved organisms. The example in this question depicts MUTUALISM.
Mutualism is the type of symbiotic relationship between two organisms in which both organisms benefit from the relationship. This is the case of the LICHEN, which involves the Algae and Fungi. The algae benefits by making use of the water and minerals supplied by the fungi while the fungi benefits by using the food the algae produces via photosynthesis.
