1. Biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.
2. weathering and other natural forces break down the substrate, rock, enough for the establishment of certain hearty plants and lichens with few soil requirements, known as pioneer species. These species help to further break down the mineral-rich lava into soil where other, less hardy species can grow and eventually replace the pioneer species. In addition, as these early species grow and die, they add to an ever-growing layer of decomposing organic material and contribute to soil formation. This process repeats multiple times during succession. At each stage, new species move into an area, often due to changes to the environment made by the preceding species, and may replace their predecessors. At some point, the community may reach a relatively stable state and stop changing in composition. However, it's unclear if there is always—or even usually—a stable endpoint to succession.
3. I don’t have the video so I’m going to take. Wild guess. Just look up types of finches 
4. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation.
These barriers can be split into two categories based on when they act: prezygotic and postzygotic.

Answer:
b. the laboratory setting may not be a good representation of the real-world setting
Explanation:
The laboratory setting is different from the real world settings due to the real world settings having uncontrolled variables and conditions. Whereas the laboratory setting have controlled variables and conditions in which experiments could be performed under. The controlled or uncontrolled conditions could either influence the experiments positively or negatively.
 
        
             
        
        
        
Answer:
A plant gets energy from the sun (sunlight)
Explanation:
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
 
        
             
        
        
        
Answer: it releases it 
Cellular respiration is done by decomposers to provide energy for themselves, and the molecules of the object the decomposers eat goes through cellular respiration. Eventually, the molecules from the object are released as CO2 and H2O because of cellular respiration, and CO2 and H2O are used in photosynthesis. 
Hope this helps you:)
