Which is an example of circadian rhythm in plants? a. the flowering of the four o’clock plant at the same time every day b. germination of a pea seed once favorable conditions are met c. the tendency of carrot roots to grow toward the soil

A. the flowering of the four o’clock plant at the same time every day

Explanation:

Circadian rhythm can be defined as a rhythm or pattern that occurs in biological processes as well as in living organisms such as plants and animals.

The Circadian rhythm is a pattern or rhythm that occurs for the period of 24 hours.

The Circadian rhythm can be affected and regulated by the presence of external stimuli such as sunlight . It can also be affected by temperature and this is because biological organisms can thrive at different and very broad ranges of temperature.

The functions of the circadian rhythm in living organisms include:

a. It is involved in the sleeping and eating pattern found in human beings

b. It is involved in the flowering pattern that is observed in plants.

c. It is also involved in the movement of plant leaves as well as photosynthesis.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

carbon atoms, hydrogen, oxygen, and nitrogen.
