An ecosystem is a community of living organisms and the nonliving components of the environment. Energy flows in an ecosystem in

one direction through food chains, and a food web is made up of all the food chains within a community of organisms. Biodiversity refers to the variation in species found within an ecosystem, and it is measured in two ways: (1) species richness, which is the total number of different species in an ecosystem; and (2) relative abundance, which is a measure of how common each species is within the ecosystem. The alewife, found in the blue banded row of fish in this food web, is an invasive species found in the Great Lakes. In fact, there have been about 25 invasive species of fish found in the Great Lakes over the last century. Yet the ecosystem of the Great Lakes has remained relatively stable. According to the passage and the model, what factor(s) contribute to the lake ecosystem's long term sustainability?
A biodiversity and complex feeding relationships
B effective methods to eradicate invasive species
C low number of invasive species; high native species number
D high number of organisms in the producer and primary consumer levels

Please help me i don’t understand

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.

I tried my best hope this helps :)
