Answer:

The correct answer is option "population".

Explanation:

In ecology, a population is defined as a group of organisms living in a particular area or region. An observation of a herd of elephants will be a study at the population level, since it is comprised of a limited number of individuals all belonging to the same species. A study of a community would involve observing different species and their interactions, while a study of an ecosystem would involve studying living and non living components over an extensive geographical region.

Oxygen gas is one of the products of photosynthesis.

Which reactant is the source for oxygen gas and how is it released?

A .

Water, released when sunlight splits it into oxygen and hydrogen ions

B .

Glucose, released when glucose is broken down into carbon dioxide gas, oxygen gas and water

C .

Carbon dioxide, released when sunlight splits it into carbon and oxygen gas

D .

Electrons, released when they strike the chloroplasts

Green plants capture energy and convert it into chemical energy by the process known as photosynthesis. During photosynthesis, carbon dioxide and water are transformed into simple carbohydrates and oxygen is liberated into the atmosphere.

light

6CO2 + 12H2O ----------------> C6H12O6 + 6O2

chlorophyll

Water is also used as a source of hydrogen required for reduction of carbon dioxide to form carbohydrate.

Water is oxidised in presence of light and chlorophyll. Hydrogen is removed from water and oxygen is released as follows:

light

4‎H20 ---------------> 2‎H20 + 4H+ + 4e− + O2

chlorophyll

or,

2‎H2O ----------------> 4H+ + 4e− + O2

Hence the source for oxygen gas is water and it is released when water splits in the presence of sunlight into oxygen and hydrogen ions.

So, the correct answer is 'Water, released when sunlight splits it into oxygen and hydrogen ions'.

Answer:

the penguins have a special care process since the hatching of the egg, the newborns receive care from their parents and have warmth from them placing themselves between their paws, the parents take turns caring for them and when the father is not with the chick, he goes in search of food, which he gives regurgitated, then the cris can go to a kindergarten where others of the same age are cared for by a herd of penguins, however his parents go to the sea and feed and continue to bring food to their son, this process it is kept until they change plumage and are ready to get their food on their own.
