Correct answer: A). Sunlight and nutrient availability

Sunlight and nutrients are the two important ingredients that are required by the plants in order to carry out the process of photosynthesis.

Green plants also called producers and they are known to fix solar energy and convert it into organic form as chemical energy. It is the green plant that is responsible for the primary productivity of the ecosystem.

Hence, sunlight and nutrients are the correct answer.

Disruptive selection events select for _______.
Natalija [7]

The right option is; extreme traits

Disruptive selection events select for extreme traits.

Disruptive selection is a type of natural selection in which organisms with extreme traits are favored (such as in reproduction) over organisms with intermediate traits. This type of selection results in increased traits differences with increase in frequency of the alleles for the extreme traits. Disruptive selection can lead to the digression in a species line.
