Answer:
We can predict the ways organisms will interact in different ecosystems by comparing the NICHE they fill.
Answer:
B. the appearance of lichens and mosses in an area where a glacier has recently melted away
Explanation:
Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.
Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.
According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.
Snow falling on glacier would be an example of atmosphere-cryosphere interaction.
B and E are likely not to be found in butter (fat).
Carbon, Hydrogen, and Oxygen are the usual elements of fat. I have added a photo below that shows the elements in some various fats, take a look.
