Answer:

Photosynthesis.

Explanation:

Photosynthesis may be defined as the process by which the plants prepare their own food by the use of sunlight and chlorophyll. The light energy is converted into chemical energy for food storage.

The early environment of the Earth's atmosphere is highly reducing. The photosynthesis at an early environment causes the formation of the traces of oxygen. The water molecule will breakdown into the hydrogen and oxygen by the use of the ultraviolet light.

Thus, the answer is photosynthesis.

Description of a blue shark
Westkost [7]

The aerodynamic shape and lightness of the blue shark body allow it to move “elegantly” across the oceans. It exhibits countershading like many other sharks. The upper part is an indigo blue tone while the ventral and the sides are white.

It has a long caudal heterocercal fin. The second dorsal fin measures almost half the size of the first and its pectoral fins are unusually long compared to other sharks. Its eyes are large, its teeth are triangular, and it has a conical snout.

It reaches a length ranging from 3.8 to 4 meters and weighs about 240 kilograms. This species presents slight sexual dimorphism since the female tends to measure little more than 1 meter in comparison with the male.

would you expect plants that normally live in the dessert to exhibit more pronounced phototropism than forest dwelling plants?
dsp73

No because they need water which comes from rain. Phototropism is the growth of an organism which responds to a light stimulus.
