Think of a change that can occur to an ecosystem and the populations that live in that area. In what ways can the different popu
Alex73 [517]

Answer:

There are several environmental factors that causes changes in the ecosystem and the population of that area such as invasive species, extreme weather, land use change, pollution and disease.

Lets take invasive species as environmental factor. Introduction of invasive species can cause a huge change in the ecosystem and affects the native population in that area. it increases the competition for food resources and decreases the survival rate of their preys.

For example: Water hyacinth (Eichhornia crassipes). It is an invasive plant species that has very bad impact of native population as well as other population, like it reduces biological diversity, oxygen loss, decreased phytoplankton productivity,  eliminate plants that animals use for nesting, and alter animal communities by blocking access to the water.

Thus invasive population can affect population by reducing biodiversity, water shortages, decreasing availability and quality of key natural resources, disturb the food chain and can cause natural calamities.

Invasive species affect the resources that native species are using and that decreases the carrying capacity of the native population as it disturbs the whole food chain.

1) Adenosine triphosphate (ATP) is thought of as the "molecular currency" for energy transfer within the cell. Function: ATPs are used as the main energy source for metabolic functions. They are consumed by energy-requiring (endothermic) processes and produced by energy-releasing (exothermic) processes in the cell and Cells store energy in the form of ATP; cells make 36 ATP through cellular respiration.

2) Energy is normally stored long term as carbohydrate, in plants the storage polymer is starch whereas in animals the storage polymer is glycogen. Both of these are formed from the monomer alpha-glucose (C6H12O6). When energy is required by the cell, storage polymers are hydrolysed to yield glucose molecules, which are the starting point of respiration, a series of chemical regions yielding ATP, the universal cellular energy release molecule.
