Answer:

The scientific study of life, called Biology, can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has  emergent properties that result from interactions among component parts. Life's basic unit of structure and function is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, nutrients and chemicals cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of evolution all of life is related by common descent. Life was diversified as natural selection had led to the gradual accumulation of adaptations that fit populations to the environment.

Explanation:

Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.

Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.

Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.

Answer:

Rabbit's population will reduce drastically

Explanation:

As it is clear from the given description, that drought adversely affects the production of flower and berries and hence the population of rabbits depending on berries and flowers will be adversely affected. Therefore, there are high chances of rabbits dying because of insufficient food during drought

Also, the foxes and hawks feed on the babies of rabbit. This further reduces the population of rabbits as the new ones are killed before attaining fertility.

Overall due to both predation (by foxes and hawks) and the drought the population will reduce drastically.
