Answer:
When light energy is absorbed by a chlorophyll molecule its electrons gain energy and move to higher energy levels in the molecule
<span>It is process through which plants and other photoautotrophs generate carbohydrate and oxygen from carbon dioxide, water and light energy in chloroplast. It is two stage reaction-
1.Light dependent reaction- in this sunlight is absorbed by chlorophyll and converted into chemical energy and stored in the form of NADPH and ATP. It takes place in thylakoid membrane in chloroplast.
2.Light Independent Reaction- in this energized electrons from the light dependent reaction provides the energy to form carbohydrate from carbon dioxide molecules. It is known as Calvin cycle.</span>
Answer:
This question lacks options, however, primary succession will be explained for detailed comprehension.
Explanation:
Ecological succession is the gradual series of changes that occurs in an ecosystem, charging it's structure and composition over time. It is of two types namely; primary and secondary successions.
Primary succession is characterized by the "LACK OF NO SOIL". It begins on a barren piece of land e.g rocks, with no form of life previously known to colonize the area. In primary succession, the barren land is first colonized by organisms such as lichens etc., which are collectively regarded to as PIONEER SPECIES.
