Stells [14]
The correct option is B.
The area described in the question given above is desert. Most plants in the desert either have small leaves or no leave at all, in order to regulate the amount of water that is lost to the atmosphere via evaporation of water from the leaves. Most deserts are found within the latitude 30 degree north and latitude  30 degree south. Some deserts can also be found around mountain. The temperate range in desert is quite wide. During the day, the temperature may be as high as 50 degree Celsius and the temperature may drop below zero degree Celsius in the night. Thus, it is always very cold at night compares to during the day.

nikdorinn [45]

The idea was that fertilizing the ocean and seas would lead to the in increase growth of phytoplankton population.


The oceanic plants do not release carbon dioxide into the air when they die because the sinks into the sea carrying with them the carbon dioxide for several centuries. This would then decrease the levels of carbon dioxide from the air as plants absorb carbon dioxide from the air during the process of photosynthesis.

Which of the following is an example of an adaptation that allows similar species to live in the same environment?
Andrei [34K]

Answer:

B. Both mussels and barnacles live in the tidal ecosystems.

Explanation:

Mussels are <u>small bivalve molluscs that are adapted to both marine and freshwater ecosystems</u>. Barnacles, on the other hand, <u>are arthropods that are adapted to marine ecosystems. However, both are adapted to shallow and </u><u>tidal</u><u> zones</u>.

Both organisms are small and have the capacity to live in tidal ecosystems where they thrive and play important ecological roles. For instance, barnacles are filtering organisms, which is extremely important for the food chain, and mussels filter out significant amounts of excess nutrients and metals, that is, they make the water more suitable and clean for organisms to live.

As they are both adapted to tidal ecosystems, this would be an example of an adaptation that allows similar species, in this case mussels and barnacles, to live in the same environment.

Which of the following would be a good adaptation for an organism that lives in the intertidal zone?
barxatty [35]

The right answer is A.

The foreshore, also called intertidal zone, is the tidal zone of the tides on the coast. The alternation of the tides which discover more or less the substrate according to the phases of the Moon determines the conditions of humidity, salinity and temperature of the foreshore.

These variations lead to a vertical ecological structuring of the foreshore in so-called supralittoral, mediolittoral and infralittoral stages. The floristic and faunistic stands of these stages are distinct, according to the requirements of organisms in water, salinity and temperature. Therefore it would be beneficial for organisms living in this period that it can live without depending on the water present in their environment since the presence of the latter is inconstant.

The foreshore is divided into several floors that correspond to different ecological conditions. These coastal stages are defined by the duration of their emergence and therefore by the level of the different tides.
