Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water, "light", and sunthesis, "putting together". In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP).
You subtract the number of protons and the mass to get the number of neutrons.

Answer:
the correct answer is option ( B )
Answer:
See the answer below
Explanation:
<em>The carrying capacity of the ecosystem for the white-footed mouse reduced in response to the changes in the amount of worm infected mice in the population.</em>
The carrying capacity of an ecosystem for a particular population of organisms is the maximum number of organisms the ecosystem can support based on the resources it has.
<u>The ideal carrying capacity of the ecosystem for the white-footed mouse oscillates between 36 to 40 in graph 1. The carrying capacity range reduced in graph 2 from 36 - 40 to 30 - 36 as a result of changes made to the number of mice infected with parasitic worms in the population of the animal. </u>
Thus, the introduction of more worm-infected mice into the population probably put more pressure on the ecosystem resources thereby reducing the carrying capacity.
