Answer:
There are two types of ecological succession:
Primary succession:
Primary succession occurs in areas which were previously devoid of life. There were no organisms living in this area before. For example, lands after new glaciers or volcano eruptions. Firstly, microorganisms begin to habitat this land, followed by plants like lichens, shrubs etc. Finally, complex life evolved from these.
Secondary succession:
Secondary succession arises in areas where life existed before but was destroyed due to natural circumstances like flood, fire etc. Small grasses inhabit this land first which are taken over by trees over period of time.
<span>Answer: There would be more cellular damage
from harmful products of the light reactions of photosynthesis.</span>
<span>Photorespiration
is a light dependent reaction that uptake molecular oxygen and release of
carbon dioxide from organic compund. Photorespiration is linked to
photosynthesis by ribulose-1,5-bisphosphate carboxylase. However, consequence of mutation in plant due to
photorespiration deficiency will result into </span>more cellular damage from harmful products of the light
reactions of photosynthesis.
This dandelion siphonophore is the first we observed on this expedition. Found at approximately 2,530 meters (8,300 feet) depth, we were able to see the feeding tentacles extended around the animal like a spider web as well as the pulsating nectophores, found just below and around the “float,” which helped to keep the central body suspended.
On the rare occasions we encounter these invertebrates, they appear from a distance as a pulsating, faintly glowing, orange-yellow ball that seems to hover just above the bottom

Explanation:
Foxes dig out dens to provide a safe underground space that is mostly used for raising fox cubs, also called kits. In urban areas, the dens - known as earths - are commonly located under sheds, but they can also be among tree roots, in bushes or on railway embankments.
