2. Which factor has the greatest influence on the

variety of species that survive in different regions

of a marine habitat?

A.

depth of light penetration

B.

daily fluctuations in temperature

C. size of predators

D. average annual rainfall

Marine habitat refers to the distribution of organisms, plants, and aquatic animals in the oceans, seas, lakes, and ponds.

The factors such as oxygen demand and light penetration play a crucial role in determining the type and distribution of organisms in the different regions of the habitat.

Light penetration affect the marine ecosystem as:

Thus, light penetration plays a crucial role in determining the variety and distribution of organisms at different depths.

The correct answer is Option A.

depth of light penetration

Explanation:

light is important in marine habitat, the distribution of organism, density and the type of organism is determined by the depth of light, the energy and how well the light can travel because most of the organism depends on light.

Green Plants, some algae and cyanobacteria survive through the production of their own food via photosynthesis. Photosynthate produced through photosynthesis is what is transported from area of production to other plant part where it is needed.

Photosynthesis can not be achieved without light penetration because light is what supplies the energy needed for the reaction.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
