Answer: 3. gravitropism
The movement of plants in response to stimuli is called as tropism. Plants respond to different stimuli like light (phototropism), water present in the soil (hydrotropism), gravity (gravitropism) and touch (thigmotropism).
Gravitropism refers the growth and movement of plant parts with respect to the force of gravity exerted by earth. The roots shows positive gravitational tropism because they are growing towards earth gravity. The shoots or stems shows negative gravitational tropism because they are moving or growing against the gravity.

Solar eclipses occur more often than lunar eclipses because in a lunar eclipse, the moon has to be perfectly aligned with both the earth and the sun.
Solar eclipses occur about 2 to 4 times per year, but the area
on the ground covered by totality is only about 50 miles wide. In any
given location on Earth, a total eclipse happens only once every hundred
years or so, though for selected locations they can occur as little as a
few years apart.
Eclipses of the Moon by the Earth's shadow occur less often than solar eclipses, however, each lunar eclipse is visible
from over half the Earth. At any given location, you can have up to
three lunar eclipses per year, but some years there may be none.
In any
one calendar year, the maximum number of eclipses is four solar and
three lunar.
<span>The correct answer is D: All of the above. Any small individual changes in the eco-system can cause larger scale changes throughout the eco system due to the interconnectivity of species within the larger system.</span>
