Answer: The night
Explanation: 
Remember that a plant does two things, it either produces energy by photosynthesis, in which case it takes up the carbon dioxide and releases oxygen, or consumes energy to grow/carry out the functions of life.
In the second case, the plant takes the glucose, or sugar, that it made during photosynthesis and breaks it into pieces, releasing energy. This step is accompanied by the release of carbon dioxide into the atmosphere. This happens all the time, but since the plant does not produce sugar and release oxygen during the night, the night is when it produces more CO2 than O2.

When new habitat is made available, organisms can diversify rapidly. this can be gradual or punctuated this process called as adaptive radiation.
<h3>What is Habitat?</h3>
The term "habitat" in ecology refers to the variety of resources, physical characteristics, and biotic elements that exist in a region and are necessary for a specific species to survive and reproduce. An animal's habitat can be thought of as the outward representation of its biological niche.
 Thus, the term "habitat" refers to a specific species and is fundamentally distinct from ideas like the environment or vegetation assemblages, which are better described by the term "habitat-type." 
The physical elements could consist of things like soil, moisture, temperature range, and light intensity, for instance. The availability of food and the existence or absence of predators are examples of biotic variables. Every species has certain habitat needs; habitat generalist species can survive in a variety of environmental circumstances, whereas habitat specialist species need a specific habitat.

ANSWER: 
Radioactive element life years = 1000/2 = 500yrs. 
So, Rock years
- 6.25/100 × 500
- 31.25years.
 
        
             
        
        
        
Explanation:
When the high energy electrons move from the reactive center, they are conveyed from one chain protein to another as the energy in the electrons is harnessed to pump H+ ions from the stroma into the lamellae. The electron will ultimately reduce NADP+ to NADPH and the electrons in the reactive center will be replaced by high energy electrons from the splitting of a water molecule in photolysis. The energy of the sun is used to split the water molecule. The high energy electrons then undergo the same cycle as the previous electrons and the cycle continues. 
Eventually a proton-motive force is created across the lamellae membrane. This potential energy of the high H+ ion gradient is used by ATP synthase enzyme to phosphorylate ADPs to ATPs.
