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.
<span>The Growth of the spore-producing organism takes place by mitosis. Moisture helps the cells divide.
However, the spores must also be attached to something that will provide food for them.
These organisms cannot make their own food. When the spore has enough moisture and food provided for it, mitosis continues and the spore grows into an adult organism.</span>
B. Golgi Apparatus.
All eukaryotes have a Golgi apparatus though not all have the other organelles named above. They all have it because of it's indispensable function, transportation of lipids and the preparation for secretion an secretion of proteins.
The other part mentioned have important functions but that varies from cell to cell according to their functions.
